Short answer: yes Long answer: why the hell not

You know as I read through all the comments it's funny how some people claim to know so much about a gun they don't own. Yes , speed kills barrels, but it also kills anything it hits. So what if you only get 600 to 1000 shots out of a barrel. That is the cheapest replacement for so much fun and bragging rights. Go for it brother. Don't let the negative thoughts bother you.

I love my 6.5x300 weatherby. It loves the 127 gr. Barnes LRX

I would be excited to see the 300-378. A true beast, but interesting to see by how much it outperforms the 300

I say absolutely yes you should. Ive got 2, an Accuguard and a Vanguard. Shouldn't have any trouble getting 1" groups with factory ammo. 127gr. LRX. Need brass? Buy the silver box 140 grain load. Cheaper than new brass.😮 Dont give a hoot about efficiency if i want go fast. Burn powder like a 427 cu/inch V8 burns gas, both go fast. I hear tails of a 7mm-378 on the horizon 😊.

I think you should go with the 270 Weatherby mag. Its more efficient than the 6.5-300 and hangs pretty close with it for velocity.

Yes your going to love the 6.5~300 Wby. It will stack dimes on accuracy with some practice time at the range. You can get it in a Vanguard pretty affordably. Cant wait for you to join the club. 👍👍

i have to say that i'm hyped to see what a 6.5-300 can do (like a 26nosler but this is another story) ! 6.5 rpm vs 6.5 prc can be interesting too

Don't forget about the WBY 6.5 RPM is a nice cartridge mine is awesome. Keep up the good work really enjoy watching your content 👍

They are fun, accurate and you don't need a muzzle brake, I don't know why I purchased a 6.5 creed and prc I will never hunt with them having the 6.5 x 300, however in the end you don't need us to answer your question it is obvious you answered it yourself. Just share with us when you purchase your 6.5 x 300 WBY. HA HA

I’m remember this poll and was torn about the choices since I would have loved for you to have several. That said, if you’re gonna have a 6.5 it might as well be a weatherby. Hey, if you run out of brass, just grab a few 300s and neck them down haha.

I have a Mark v in 6.5x300 and all I can say is, wow. It's the fastest, flatest, cartridge that I have. 127 Barnes smoking. Shot a big male bobcat with it at about 120 yards and the cat fell before the sound left the barrel good. I mean it disappeared so fast I thought I missed. Went down to it a d it was laying there on its side. It had spun that cat 180 degrees and flipped it over at the same time. Bad to da bone.

I started looking at this cartridge a little differently when Dave Petzal wrote that he replaced his 300 Win Mag (not Wby Mag) Accumark with it and found it to be just as effective on game. Dave has also written before that he has used both the .270 Winchester (with 150 grain bullets) and the .300 Win Mag (with 180 grain bullets) extensively for hunting and cannot see a difference between them in terms of effectiveness on game.

I think you should get a 6.5-300 Weatherby. It would be really interesting to see what you can do reloading for it. I have a 6.5-300 Ultra Ultra Mag. I haven’t done any shooting with it yet though. I’m waiting on dies. I know it will be disappointing with a 26 inch barrel but if it shows promise, then I will probably keep messing around with it.

Get the 338-378 also

Before considering a 6.5-300, play around with lighter bullets with your 340 Weatherby. Try some Hammer 180-200 grain bullets and compare that to the 6.5-300. If you want to get a 6.5-300 to add to your stable get it and never look back. A buddy has one in the back country 2.0 and loves it.

I wish wby would just offer 30” barrels on these over bore cartridges.

I have one and really like it. Its an expensive rifle (Backcountry 2.0) and the ammo is expensive. I really only use it for hunting as such. Feels like a waste to own it to use it so little, but im getting into reloading so hopefully that offsets the cost and allows me to shoot it more.

Love my 6.5-300

Hey man, I’m fairly new to the channel but been loving the videos on the Weatherby cartridges. You inspired me to dip my foot into them. I just went and picked a 30-378 Thursday. Also, to make it better I’m local as well. So while you wait for the 6.5-300 we could have some fun with my 30-378.😁

Yes, if your gonna go for an overbore speed demon, the 6.5x300wby is the way to go. People talking about efficiency, if efficiency was the topic then this cartridge wouldnt even be mentioned nor would a 26 Nos etc. This is about flat shooting and pure nasty sweaty sexy speed. I say good choice sir. I have one in a Vanguard i got just for fun, killed 2 deer with it last season just to try it out. 127gr lrx, one ran hunkered hard with tail down for prob 12yds and killed over and the other is my biggest bodied buck to date, he went nowhere. 1st buck was approx 80yd shot, big guy was 218yds. Hit hard, killed quickly, but neither bled at all. Maybe thats on the lrx bullet but i dont like that. Still was fun to try it out. Fun gun to play with a little. I say go for it.

Yes, it's pure fun in a cartridge. Speed, a lot of theatrics with smoke and sound, but still quite mild to shoot.

I have one in vanguard synthetic. I bought it when it first came out. Now I wished I would have gotten one in the mark V. Love the caliber.

Go the 270wby man! Barely any content on KZfaq of that caliber but alot of people are interested in it.

I would be awesome if Weatherby would make a 7mm-300 Weatherby There is talk of maybe 7mm-378 Weatherby that would be awesome either way

Absolutely

Its a HOT ROD!! I like Looks of that 6.5 RPM. But dont need the 6.5/06 I have. Hahahaha. Kewl stuff man! ❤❤

Get a mark V accumark if you buy one, owned mine now for round 5yrs now and she still going strong 💪🏻

If you want speed and more recoil than a 7rem mag. Then yes!! I just finished my own research on the 6.5 I choose the 6.5 PRC Only because it has great ballistics and is more affordable than the Weatherby factory rounds. Yes the 6.5 rpm is a little bit faster the 6.5-300 is a lot faster. But for ethical hunting distance the 6.5 PRC Is very adequate. But if you don’t care about barrel life,recoil,or ammunition cost then the 6.5-300 is the best choice.👍👍

The 257 Wby Mag and 6.5x300 Wby Mag are the two Wby cartridges that I have the most interest in and in some of the Mark Vs I can get them left handed. After the speed issues with the 7 PRC you need a true speed pick me up

Gotta try em all.....within reason of price an availability. Then maybe a Weatherby only cartridge show down

I've had mine several years. Killed many mule deer, nice whitetail buck too. But I used the factory load with 140 grain swift aflame. Awesome!!! Buy it!!!!!😊

Absolutely. Its my next as well

I use US869 in mine and it shoots consistently faster than what the book says. Especially with heavier bullets.

Yes, or 30-378

It's not about want,it's about need.

270 Weatherby Magnum

Yes! Absolutely! I have a 6.5-300 and LOVE it! I always hated the 6.5 manbun and the hype as I was a 30 cal guy. Then I won a Mark V Ultra Lightweight in 6.5-300 and fell in love with the rifle/cartridge. It’s mild recoiling and crazy fast with a ton of energy dumped into the animal. I’ve switched over to lead free as I eat only wild game and don’t want to add to much lead into my families diet (no matter how awesome Accubonds work). So the speed of the 6.5-300 has been amazingly effective with Barnes 127 gr LRX. I’m going to be working up loads with 130 gr Hornady CX though as well for a bit more oomph (not much but it’s got better SD) for my mountain goat, whitetail, mule deer, elk and moose hunts this fall. And it has taken 3 big whitetail, and a big black bear this past season with more DRT than my 30-06 ever had. That’s what really sold me on it; seeing them drop in their tracks or only going 20 feet. If you’re using it for longer bullets and target shooting I’d suggest the 156 Berger… just don’t hit anything within 400 yards or it’ll grenade before it gets into the body cavity! It is a speedster for sure!

Definitely should

I would say go bigger. Get the 378 weatherby magnum. That is my dream cartridge.

Get one! Get one of each! Insanely overbore! Just know you're the reason there's a powder shortage.😂

6.5x300 Flattest shooting commercial round made.....enough said.

It's a great way to go through powder by the shovel full.😉

Get an accumark at a minimum. Heavier barrel. 6.5 300 heats barrels up real fast!!

Yes!

I shoot a custom built 26 Nosler, was really hoping to see that comparison. Nonetheless another enjoyable video!

I've been struggling with that decision myself

Go a head and get the twin turbo man bun lol. Just joking that’s a speedster for sure.

I feel like it doesnt fill a gap in your arsenal (not that it needs too). In my opinion a 240 or 416 would be nice end caps.

Austin I’d also say that I had great results with the Barnes 127 lrx with my rifle it’s a vanguard badlands. Very accurate and I’ve killed two bucks with the rifle and performance is good with those Barnes bullets cuz of the velocity. These bullets can withstand the high velocity and they do not blow up or blood shoot as bad as cup and core bullets. I haven’t tried anything bonded that 130 scirocco would be sweet too.

You say the 6.5 creedmoor is the most popular hunting cartridge but I feel you should double check that. It sure isn't the most popular where I live. Lots of people here have a 6.5 creedmoor but not for elk hunting. It was designed to be a paper puncher at long range, which it does well. I do think you should get a 6.5-300 weatherby because it seems to be what you want, just make sure you buy loading dies for it.

😃 You Know Austin, I Bet Jack O'Conner Heard The Same Comments About His 270 Winchester! And All Jack Did Was Keep Putting Animals Into the Record Books, While His Critics Didn't! 😜

I have a 26 nosler and it's a beast

I want the 6.5 Rpm 😃👍

Yes!!!!!

Should try out the 240 Weatherby mag best light magnum I ever shot

338rpm!

I’ve been thinking about running either hammers or Lrx. I want to get a night force 5-25 atacr and throw it on a mark 5 back country 2.0 ti with a gun works titanium suppressor and back landz bipod and custom turrets. Should be the ultimate hunting rifle. 6.5-300

As a world famous Tuber - You are morally obligated to run the 7mm Weatherby!!!!!

I would be trying those 156 bergers

Hell yeah u should.

I am really interested in that google sheets file you showed. Did you hard code the bullet drop in inches in the cells, or did you use a formula? I have been trying to figure out a formula for my own ballistics excel sheet to calculate drop with no luck.

I also think “Man-Bun”!

Did you do a video for the 250 ABLR in the .340 WM yet?

The reason why my vote for the 6.5-300 is cuz one I love weatherby cartridges there cool the rifles are great too, I like the 257 wby too but it really isn’t on par with the 6.5-300 wby cuz of the class of bullets that can be used, I’d say it is better than any of the other weatherby cartridges in its class like the 270 or 7mm weatherby. Albeit the 30-378 wby would obviously out shoot this cartridge but not far behind.

The throat is cracked by the time the rest of the barrel is broke in. 😂 I'm kidding, the 6.5-300 is wild.

I’m looking into getting my first Weatherby. I’m going between the 257 and 7mm. Held the new 307 range xp the other day and I think I’ll got with that in 257. Otherwise the mark V live wild edition in 7mm. Decisions decisions 🤔

Yes

Look at the powder capacities it requires to attain the speeds shown. I question is it worth it? In the age of range finders when all rifles have become long range shoots, if you know the ballistics of you cartridge, I can't justify the additional expense of anything Weatherby.

I have a 6.5-300 and I love the thing and it’s a powerful creature good enough to take Sasquatch I’m not kidding

You need a runoff election vs the 2nd ranked cartridge

I keep telling you; “460 WM C’mon!”

Did you get rid of your 300wby? Maybe I missed it, although thought you said you only have the 257 and 340.

If you don't get one, you'll always wish you did.

👍👍👍yep👍👍😃

Yes you should get it and reload with Barnes 100 TTSX. Push it to 4000 fps! 😂

Would you be buying another rifle? If you have a gun smith you like you could get a barrel to put in one of your other guns, it be cheaper in my opinion

Looks like by the time you work up a load and sight it in your barrel gone .

Vanguard’s have a 26” barrel;)

I thought the .375 chey tac was the flattest shooting Cartridge in the world?

It's like going back in time to the first u.s. 6.5 win mag 1958 that started the 6.5 belted magnum look up the info for that in 1958 I bet ud be surprised then to now

6.5 anything is boring but it does come in a vanguard

I was hoping for the 338 rpm . Still hope you change your mind

You will have the baddest 6.5 on the planet , if you buy one get one in the new 307 you won’t be sorry .

If you want to change the barrel between 500-1000rounds go for it

I have one a Mark V Deluxe Accumark. I’m going to get dragged around here, but this is one of my least favorite Weatherby cartridges.

As long as it's a mark V, bro

I don't Needmore

. Why don't you think about getting a 7mm Wby Mag first?

Ummmmm….yea

How much meat will it wreck?

270 Weatherby just seems more practicle. But you do you, we will still watch.

You need to get two and send me one.

No buy a 25-06 instead.

I am tired of the 6.5's honestly. I'd rather see something that you don't see often like .270 WBY or 7mm WBY.

Get a 270 Weatherby!

Why wouldn’t you compare it to the 26 nosler rather than the 28. That would be a much more 🍎 to 🍏 comparison.

26 Nosler!!

No! ........ get a 270 Weatherby!

I would not ! Barrel life is too short, and way too much recoil.
