I think I'd like a load for my 1866 that will send a 158gr @ ~1000fps.

Qiuckload shows me some slow powders that will get me to ~1400fps at <17,000 psi (SAAMI).

Is there any way to tell if 4.5gr of TiteGroup behind a 158gr and COAL of 1.55" is "safe" (38 special pressure)?

I'd hate to put undue stress on the rifle, but I've also got a LOT of TiteGroup and I'd like to use it if I could.
