A little confused about my reloads COAL:
.45-70
Chiappa .45-70 Sharps 1874
Load: Rushmore 300gr .459 ; 30.0 gr H4198. All load manuals show max OAL at 2.550. My loads measured 2.50. None would allow the falling block to close. OK, I'll check. Snap caps measure OAL 2.498 and chamber.
I re-seated the bullet until I got OAL at 2.471
So ... the question is, if manuals ALL show max oal at 2.550, and the longest oal I can chamber is 2.471 (.079 less), is it projectile configuration (FPRN vs RN) or something else causing the (admittedly) miniscule OAL discrepancy?
As an aside, the first live rounds I've tried to fire, as opposed to the snap caps.
-jb, I'll relate to another thread later
