Jensen, I hope you are watching the throat with a bore scope.
BINGO!!!! Has been great in my 300 PRC with H-1000. And my 338 Edge. But I had no reason to do it in my 2 different 28 Noslers. I think it's exactly what jensen said, you have to be smart about which calibers you choose to do it in, and you need to be smart about how much is too much.I have zero hesitation using DE +P in the right application. I feel like I understand the the pros and cons. I also use N570 when it produces the desired results on a target at 600yds. If H1000 is more consistent I will happily take the lower velocity and many of my loads are H1000.
I understand that my barrel will not last 800+ rounds and my barrel will start to degrade around ~400 rounds. I am not asking for a barrel warranty. I don't care if someone else thinks ~400 rounds is unacceptable.
I tend to run normal pressures at the expense of wear and tear on the consumables (barrel). I see loads posted from time to time that seem well in excess of the normal pressure. I would rather run a +P chamber at normal pressures than a standard chamber at max pressures. In my mind, if you are matching my velocities with H1000 and a standard chamber then you are running much higher pressures and stressing all of the parts that see the pressure. I certainly see the logic of normal pressures with a standard non +P chamber.
I would not run a +P on a high round count rifle. I would not run N570. If I expect good barrel accuracy out to 1000 rounds I am also not going to run a barn burner cartridge such as 28 Nosler, 300RUM, 30-378, 338 Edge, 338 Lapua Improved, 33XC. I am going to run 6.5CM, 308WM, 338NM.
My point is that there are numerous choices that contribute to barrel life and +P is just one of them. In my mind +P makes sense for a few of my projects where I am searching for performance rather than longer barrel life.
I do check the throat with a borescope although the limited data and large number of variables between guns makes it hard to draw any specific conclusions.Jensen, I hope you are watching the throat with a bore scope.
No worriesFordy
Thanks much!
I should not be on the Forum Posting late at night and not trust spell check.
Thanks

I agree….This shouldn't be too much to ask.Ideally I'd like one of the following 2
• Speedy Accuracy
Or
• Accurate Speed
I don't require an expressed or written warranty with either.
Yes yes. Sigh me up.250 grain bullet to 4000 FPS
Please, do tell.Has been great in my 300 PRC with H-1000.
Accuracy is different for different people. I strive for sub 3/8" groups at 100 yards.This part is not accurate.
