The farmer's gun, 9.3x62 - in 1911?. 286gr. Solid and soft, @
2,175fps.
It wasn't until the 1920's that the ballistics were improved
and according to John Taylor, poacher extraordinaire, the
improvement wasn't needed. The original ballistics worked very
well, thank you, very much.
The 1920's, 30's, etc, 9.3x57 on a model 94 or model 96 action
easily duplicates the original 9.3x62 ballistics, btw, with
today's powders.
With sized down .375" 300gr. Hornady RN's (to .366") I
averaged 2,170fps with 0.0000" to .0002" (2/10,000") case web
expansion.
So - yes, early in the 1900's, bolt action Mausers kinda took
over the more affordable big game rifle market- but, it wasn't
until the 1950's that there was a bolt action replacement for
the .450 NE - correct?(wildcats, of course were available)
