In my 60+ years of collecting hunting and reloading is clean the gun when you first get it if any debris and from there start sighting it in and clean between each 3 shots and by the time you get through that box the gun is sighted in and broke in enough to hunt with! Has worked on my Hundreds of new rifles I have owned in Any brand!

Looking forward to breaking in my new Mark V. KCR in 6.5x300 this week. I'll do my break in like this. Clean rifle to start. Fire 1 and clean x 10 Fire 2 and clean x 10 Fire 3 and clean x 12 Fire 4 and clean x 8 Done and enjoy😊

I have the PERFECT break-in procedure... shoot the damn thing and don't worry about it. A quote from one of my favorite barrel makers, you might recognize the brand if you've read their FAQ: "Break-in procedures are as diverse as cleaning techniques. ****** introduced a break-in procedure mostly because customers seemed to think that we should have one. By and large, we don't think breaking-in a new barrel is a big deal. All our stainless steel barrels have been hand lapped as part of their production, as well as any chrome moly barrel we install. Hand lapping a barrel polishes the interior of the barrel and eliminates sharp edges or burrs that could cause jacket deformity. This, in fact, is what you are doing when you break-in a new barrel through firing and cleaning."

I love my Weatherby’s, but the only way to maximize accuracy to work up a variety of hand loads. Different powders, primers and bullets dramatically effect accuracy.

I always get excited when you guys do a new podcast. So much good information from people who know better than anyone. Keep it up gentlemen!

What I got from this podcast is Weatherby doesn’t have standards or procedure for break-in. They go off their feelings. So I’m winging it. 🤷🏽‍♂️

I can’t stress trying multiple loads. I have one that shoots a certain load 2-3” with a certain load. With the same grain but different bullet it shoots 1” or better every time. I also have one Weatherby in .257 Wby Mag that shoots the least expensive ammo under an inch every time and shoots the 80 grain TTSX loads in the same hole. I set a timer and wait 10-15 minutes depending on outside temps when shooting on the bench. You have no doubt when you find the load your rifle really likes. My .257 Wby it’s the older 100 grain Spitzers and 80 grain Barnes TTSX. With my 6.5-300 Wby Mag the 127 grain Barnes LRX and the 140 grain Swift Aframe. I tend to lean further towards the 140 grain Swift Aframe factory load. Great video guys.

Great podcast. I have a few Weatherby rifles, my best shooting rifle is my 340-Weatherby Magnum. Interesting information at the end about the Backcountry TI 6.5-RPM, as much as I do not like the sticker price of the Backcountry TI I think my next rifle will be one chambered in 6.5-RPM.

great information,,,,,,thank you,,,,,

Thanks for the information.. I never have done a break in on my rifles.. I will do it on my new 240 mag!

Thanks for the nap.

So excited with my new weatherby deluxe 7mm weatherby mag . Heirloom quality rifle . I happened to win it in a raffle with 10 boxes of 160 gr weatherby ammo . So the break in on this ammo is 110 bucks lol😂

I live in eastern suburbia, and the only place I can shoot is a commercial indoor range. They're not going to let me clean the barrel between shots, and I'm not driving to the range, taking three shots, then going home to clean before the next three shots. So, cleaning every 1 or 3 or 5 shots for 20+ shots = not happening >> just not practical. Also, I get the lane for one hour INCL setup & cleanup...I can't shoot 3-shot groups with 10 minutes of cooling after each group.

I have an about a 300 Wby Mag Ultralight, with Bell and Carlson stock that shoots poorly (3"@100). I gave up on it for many years but recently came back to it to try to resolve the issues. I noticed that the stock was in contact with the barrel on the left side over about 4" area. I have removed this by sanding it down and I also noticed that the barrel was also touching the stock near the front. I've read a thousand forums about barrel stiffness in these models, free floating vs leaving the stock in contact with the front of the barrel. I was shooting 3" groups and now 1.5" after free floating and stock modification. Can you guys tell me about barrel stiffness and if free floating the barrel was a mistake. It is my intention to shoot some different bullets and weights to see if I can get consistent 1" groups via different harmonics.

In the 257 I like the 100 GR.

ie. Am I worried about getting all copper out or just the carbon during the first 20 or so shots?

I have a weatherby 257 and I love this gun I kill two 12 pointer and two does the first year I got the the gun but didn't like the ammunition I bought it was from horndy it did not penetrate through all the deer i kill i had to trail both bucks one went over 25o yard and the other went over 375 yards all shot through the shoulder.but it's not the gun it's the bullet. But now I hand load for it and I use barns bullets and they drop right there and never move. So you have to know what Bullets to use in this caliber it makes a Difference. But I love weatherby rifles they are great

If you have to fire form say 7mm to 257 wm , can you do that for your breaking ? Lighter load ?

Do you worry about copper build up during the break in procedure?

who's barrels are you using now?? I notice the "range certified" rifles are not currently offered?

My mk 5 300 classic shoots all 3 touching each other every time at 100 with weatherby ammo 180 grn did the same with 165 whby ammo much hS to do with the shooter to see what a gun and ammo will really do hotter the barrell more the poi changes no matter what

So in essence, it's more of a "luck of the draw." You might get one that's shoots consistently and accurate, or you might not? I guess I got lucky with my old Vanguard. Love Weatherby firearms. I wouldn't hesitate to buy another one. (I'm not a tough guy, I use a lead sled when sighting in)

OUCH!! On breaking in a .460...lol!! Be prepared

If they offer a .99 less guarantee on a new Weatherby using premium ammunition why would I need to do a break in? Am just going to give it a good clean before I take it to the range to zero in the scope. Btw the one I am getting is chambered in 240 wby am just going to purchase factory ammo even though I reload for several calibers already.

Wait a minute...... Are you just trying to sell more Weatherby ammo?😉 Just kidding, I know you guys are honest.

most of the "big" rifle manufacturer's say break-in is not needed with their barrels; a few say it's necessary only with their cheaper models; a few say it's not necessary with their barrels but does help... ...according to this guy: kzfaq.info/get/bejne/Z8yIgLeZt7LbqWg.html

Ill Tell ya what my $$$ weatherby rifle better shoot sub moa longer then 2years ! 🤔

What do u do with all of these tested guns?...hook a coyote hunter on a budget up! Ha!

You better inspect the rifles before you send them to the customers, because I received mine with the Trigger safety not engage
