Is it OK to use Hornady Critical Defense .38 Spl 110gr FTX in an early, 1960s Model 36 Chiefs' Spl?!
Thanks!

Thanks!

That Treasury Load is an entirely different beast from an entirely different loading era. I'd imagine the shallow penetration was due to too much velocity resulting in early expansion in the target.Well, I ran a few boxes of +P+ 110 gr. "Treasury Loads" through a mid-70s M37 airweight back in the day. It didn't blow up but it did go out of time and required a trip back to the mother ship to fix it.
I still have some of the stuff around but the after-action reports on that ammo weren't too good--short on penetration--so after a few years it fell into disuse.
