Lloyd,
There have been a bunch of changes in the last few year with regards to ammunition.
We can’t be sure OF ANYTHING, with regards to typical, SAAMI compliant, US produced ammunition today. All the regular manufacturers care about, is that whatever they produce with the components they were able to get this week, are under SAAMI max pressure. That is all they will care about next week, as well, with whatever components they can get then. RST, a boutique loader, does produce low pressure ammunition. But, they are the exception. You knew that.
If you are running a gun that requires low pressure (I vaguely recall mention of an old hammergun, no?) you are going to have to quit assuming anything about big industry ammos loads, and feed the gun what it needs. Sorry. There ain’t no free lunch. You can load it yourself, but, the rationale for doing so has changed. Guys used to do it to save a buck or two. Now, they load what they can’t buy, no regard to costs.
I suppose I could prattle on about my old French 2 1/2” gun, with long tubes that measure a luscious .050 their entire length, but, that would just be salting the wound, I imagine. But, it is a valid point.
Wall thickness is a thing, these days. So are Easter egg hunts for proper ammunition.
Good luck.
Best,
Ted
