if you factor in reduced oal it's probably pretty much there but you are comparing a ***** cat 10mm load to a *heavily* modified 40 at only a tenth of an inch shorter oal and a correspondingly smaller powder load. but- brass doesn't eject far, does not get mangled, recoil isn't excessive, no failures to feed like you'd expect if timing was off.
Powder is not compressed but it is full. With a faster powder this would not be good, but with this particular powder, this particular boolit, it's fine. There is no book data for this bullet how would you work it up? using data that was published with a .650-.680" jacketed bullet? Wouldn't there be some discrepancy there too though leading you to work your own load?
It is a safe load, I have loaded higher to where stresses of the pressure start showing up then backed down to where the groups tightened back up. I'm not concerned about the gun wearing out, it's just a g22 trade in, but if something cracks i'll be sure to post back as that would be *dangerous*, not just perhaps theoretically more wear and tear.
i loaded it to my personal max of brass deformation and then came back down to where the accuracy comes together. definition of working a load.
i went into production, a few hundred loaded up this afternoon. i wonder if i just dialed in to buffalo bore, doubletap or underwoods load? all i know that in this gun the mechanics aren't being stressed from a little shooting. i'll test in the 23 tomorrow, that one has a 24 pound recoil spring and factory barrel. Then I've got a few k brass to load up, weather permitting more casting, so I will be sure to let everyone know if my gun fags out during plinking.
I'm happy though. Finally got all parts of the equation dialed in to a really nice combo. I just post here because during research I did not find helpful information. Perhaps this will provide a piece to someone else's puzzle and be helpful in the future.
It's not a limp wrist load, but honestly if recoil hurts someones delicate constitution shouldn't they take up another hobby? I hear knitting is the rage with the ladies. Haha, just kidding, it doesn't recoil that much
