For sending me some 314299-GCRN to try, before spending a ton of money on casting equipment.
Well I finally got to shoot them through my 1909 Argentine Cavalry Carbine and my 1908 Brazilian
(Argentine) Carbine. Unfortunately the resulting groups were not impressive to say the least.
I'm sure it's no fault of the bullets, I pulled the loads out of Lyman Cast Bullet Handbook, using
IMR-4227 and IMR-4198. Both barrels slugged out at .312" and these are the first cast I've put
through these Carbines. Groups were around 4"-6" @ 25 yards in one gun and 6"-8" in the other.
I did decide to try some .313" bullets of the same design, and they should arrive soon. (1 week)
so any suggestions at this point? and thanks to all that respond.
