OK, wait a sec here.
We are NOT seeing reports of Buffalo Bore, Doubletap or Grizzly Ammo rounds trashing guns. Now part of that is likely that they're premium fodder and few can afford huge diets of the stuff. It's also likely that people are shooting premium ammo out of premium guns...this is connoisseur-grade stuff.
But what Tim Sundles at BuffBore claims he's doing is using very modern quality powders combined with pressure test gear to do "long duration burns" at peak pressure, without going over max.
In other words, say you've got a caliber that tops out at 35,000psi (SAAMI) like the 357Mag. Tim is trying to bring the pressure up to 35k or close to it as soon as he can and then "hold it there" long enough to put some real heat on the slug, yet without doing a pressure spike that blows the gun.
In theory, 35k for 2 milliseconds will net you as much bullet energy as 70k for 1, yet the latter risks blowing the gun to bits while the former doesn't.
We saw this in spades during the transition from black powder to smokeless. Two loads pushing the same bullet at the same speed means the same "bullet energy", but the longer burn time of "holy black" meant peak pressure was way lower. Smokeless loads blew a lot of old guns up.
You can ONLY explore the absolute ragged edge of the envelope the way BuffBore and the like do with pressure test gear that handloaders don't have access to.
So Freedom, the fact that YOUR hot loads massively exceeded sane pressures doesn't mean that a load from a pro ammo house will.
Now with all THAT said, my vintage Charter Arms Undercover 38Spl is rated for only a moderate +P diet if at all. Ain't no way I'm going to feed it Buffalo Bore 38+P!
I *will* however feed BuffBore's highest-end 357s into my Ruger New Vaquero with no qualms at all. It's cylinder is slightly beefier than a GP100's cylinder...which along with the 686 is also a gun I consider strong enough for the wildest stuff BuffBore and the other two "thermonuclear club" companies mentioned make. I used some of DoubleTap's gnarliest 357s on a bowling ball once, split it in half with one shot and send pieces of the concrete core flying over 20 paces.
Those guys are not kidding around, but they're also not blowing people's guns up.
