It's a Saturday night double feature, folks! Don't miss the 6.5 Grendel video I posted here: kzfaq.info/get/bejne/ha2aaq1nqdTbYqs.html

That is a crap ton of ammo ready to shoot. Can't wait for the harmonics testing.

Check out all that ammo! So stoked about the barrel harmonics video!

Is it Christmas? Feels like it with 2 new videos in one day!

So now we need a test of the flash hider / suppressor / and nothing all in the same charge weight. cool video keep up the good work.

Lookin forward to the harmonics testing!!!

Berger manual has always been stupid conservative with powder charges. Keep up the great work!

Awesome, a double feature! Can’t wait to watch the Grendel video next. Did I see a box of .257 Roberts dies in that stack of dies? I would love to see a series on the .257 Roberts. I think it overdue for a resurgence. A great cartridge that is good for deer and varmints with light recoil.

Dude, I chuckle every time you say: didn’t blow our face off. You should trademark that. LOL

Johnny thanks for all your good work.

That was dramatic. Great info Johnny

My old chrony f1 always freaks out when using led lighting... just a thought... Don't ya just love the giant fireball seen, magnified by scope settings, with no muzzle device. I always find it very distracting. great vid, can't wait for the horrormonics testing.

Building a 10.5 inch ar pistol for alternate season. Your butt kicking series is helping me a a ton! General reloading question: can I reload without a chronograph if I'm staying under published max charges? I wouldn't start at the max charge or course work my way up looking for presure signs. Any other tips to reloading without a chrono?

CCI #41 is the best primers for 223/5.56!👌👍🇺🇸🇺🇸🇺🇸

I think you should draw your intersecting lines for your point of aim, and then put your orange dots 3moa down and 2moa right, and almost every video you will have several shots hit them. That way it's not a wasted dot! 😜

350 rounds of Creedmoor....been busy much? Nice work...

Ready to buy the funnel and adapter/s ( .223, .260 Rem, and .308 please). Good opportunity to try "the lump";

Quickload (w/ LC Brass h20 capacity, 2.26 seating depth) shows 24.5g N540 as 49,995 PSI. PLENTY of room to go. Maybe another grain.

Hi thanks for your great videos! Having a 222rem with a 1/9 twist barrel i would be curious to see what velocities you can achieve with vihta powder and 55-60gr bullets. Could you try something? Thanks a lot

It is because of case content depending on the brand of brass why the loads published are so different

This is a truly strange realization. In shooting custom 75 gr everglades FMJ HP. I have a 24 in barrel with a 1-7 twist. I have tested R-15, TAC, VHT N140, N540. My best groups all have been with 24.0-24.2 gr. I was very surprised to discover this. Watching this and other videos show very similar results even with varying barrel lengths. Just throwing this out there.

Looks like maybe I should add a YHM "Thread protector" to my midway list. I never ordered one because they look heavy. Figured there mount was heavy enough.

What did you say the twist of the barrel. I know you have said. But I can’t remember. Thanks. Good video

Hey Johnny, try coating/tumbling your jacketed bullets with Hex Boron Nitride fine grade power. I believe you'll find your Std Devs. nearly cut in half. $16.95 on EBAY for an ounce.

I have the Lyman funnel set, does not work well for .223. Works well for some other calibers though.

a lot of fire from the muzzle = wasted energy/powder. i understand that picking most accurate powder that can push bullet with highest velocity is in most cases will result in lots of un-burned powder granules on exit. removing suppressor just made it so much more obvious. it literally hurts to see expensive powder literally going to waste burning outside the barrel and not pushing the bullet. I wonder if there are powders that can burn almost completely by the time bullet reaches the muzzle. i should say that i know that there are powders like that. perhaps ones catered to SBRs and pistols, but i mean what are those powders and how do they perform. I think, Johnny, this could be potentially an interesting topic to dive into and explore.

I've got an off the shelf 10.5 inch barrel that has gained about 4moa of precision loss over the last 500 rounds. Total rounds through the barrel is about 1200. The bcg scope and shooter have all been eliminated from the equation as my son is shooting a second barrel from the same lot and we have swapped all other components during testing over the last few days. Both guns are exact twins. His barrel is about 2moa mine is 4-6 moa. We both clean our barrels with bronze brush and frog lube with patch wipe-down after each outing. Our rounds have mostly been 50gr zmax using AA5744 at 2600fps we always split the same batch of loads. Really perplexing situation. I never imagined such a quick drop in precision. My groups are nice and round and evenly spaced yet very spread out. Any thoughts? I'm totally shocked.

Hey Johnny-can the can add fps ? Is that something to consider when trying to get bullet speed up?

Why didn't you use your Magnetospeed?

I have the lyman funnel kit . It sucks its too heavy just spend the money and get the area 419 funnel kit it's the tits

I was watching iragveteran888 on one of his videos. When you are doing your testing and having a stray bullet jump, could that be a cause of a bullet being a little lighter than the others. So if you weighed each bullet from heaviest to lightest and used the ones that were closest in weight, wicks would that give you a better grouping. Keep up the awesome job!

Yikes.. imagine if you had to buy that much 6.5 Creedmoor ammo today. Probably $600.00 or more

Theory on relatively poor accuracy without muzzle device: The crown of the muzzle on my 10.5" 5.56 pistol is completely flat. Not conduscive to any sort of accuracy. Maybe check your muzzle crown?

It's kind of obvious you should leave that suppressor on all the time.

Interesting. How many shots you think you have on that barrel now?

Did you have carbon fouling on the crown?

I recently switched to Saturn powder funnels specific for each caliber and have to say i am pleased. Check them out

Try to shoot on a softer surface and see if It makes any difference. I bet it will

Are you using small base dies?

I know this is off topic but have you heard from elvis ammo lately? he seems to be missing.

Is 540 bulkier than 140?
