Maybe have a friend stand and watch for gray ' poofs ' in front of the target.
I dont think anything under 350,000 rpm would destroy jackets in a barrel that isn't really rough
I've (mostly) stopped buying factory rifles and started re-barreling.
Last year the new barrel was a second 30 Nosler. This year is a new 223 Ackley Improved.
Guess I'm going another direction, lol.
I've had 270ai, 6mm rem ai, and my favorite 260ai. Always wanted a 223ai .
A compromise in performance and accuracy will probably be detrimental by trying to use the same powder.
The exception would be 130gr in 270wsm and 140 to156gr in 6.5 cm. Then H4350 could work for both.
I use Retumbo and 150gr vld in 270wsm. I use H4350 and rl16 and 140gr in 6.5 cm.
Those...
140 vld hunting. 3260 fps MV. 26" Pacnor 8 twist barrel.
Retumbo, gm210m standard match primers.
Shot her at about 250 yards, should be about 2850 impact velocity.
This turkey egg eater was dispatched the same morning...no hats were made.
Those 200gr Hybrid targets are serious business.
I finally pulled the trigger on a doe at 250yds, first time I ever had to take a Texas heart shot. Ragdoll tossed her, lights out. No meat loss.
So, this is a different 30 Nosler but it still fits this thread. It's a 9 twist shooting 200gr Hybrids at 3120. Still many yotes to go. Remember, I'm not calling these mongrels I'm just sitting on the deer stand. When deer season is over were going to go at night calling but these TN yotes get...
I'm not sure if the Willis die is available in the .378 case diameter. I thought they only made it for standard belted magnums ( 300wm, 7mm RM, ect.)

So, all my life I've been a center fire rifle fanatic. I carried a 380 revolver forever, shot factory ammo.
About five years ago my friend asked me if I knew what century this was!! At that moment I thought, " this azzhole is going to cost me a lot of money "!
I started trying on semi auto...
I just got an 5" Sig Xten. I'm going to start with 180gr HAP bullets.
From reading it seems like Accurate no. 9 might be a great powder. ?
Anyone use AA 9 with 180gr bullets.
I've owned several 300wsm and even more 300wm barrels.
They are not ballisticly the same. The WM will best the wsm by 150 to 200 fps at the same pressures. The wsm is handicapped by short action and magazine limitations with long bullets also.
I still love the wsm and my next build will be on...
Before sunrise and after sunset they eco in surround sound from all the surrounding ridges. Spooky and haunting. It sounds like a community of over 30 within a few miles.
I'm at my farm in SW Tennessee for rifle season, our whitetail heard is real thin this year...because of these varmints!
I'm supposed to be putting deer in the freezer by the way.
I will say though, a 185 gr Hybrid target at 3290 fps muzzle velocity is pretty efficient at dispatching...
Get a 7mm Remington magnum. It will out run the 7 prc with less pressure. ADG has outstanding brass available.
Every Hornady PRC cartridge to date (6.5, 7mm, 300) has had sizing problems after a couple of firings because of the .200" line not sizing enough. Guys are having to fix their...
