Alright, I take back my comments on here about the
perfect roundball deer rifle. A .58 caliber with a
1:116 twist rate is not a good idea. It would be fine
with a Forsythe rifled barrel using hard cast balls
with a wad behind except for the extreme recoil
generated. Pure lead roundballs would deform at high
velocities and thus penetration would decrease. Pure
lead roundballs have amazing penetration but only at
lower velocity. Hardened balls won't deform easily and
will plow thru bone. Such a slow twist rate would
allow much more of a powder charge to be shot
accurately but with lesser powder charges accuracy
would suffer. What was I thinking? Thank God for
people patient enough to explain. A .54 caliber with a
moderate twist rate (1:70 or so) using pure lead balls
and a patch is a much better choice. It was stated
that such a rifle would shoot flatter out to normal
range. A vast majority of deer are taken under 100
yards. Larger balls have more energy out to a longer
range than smaller balls but have more of an arched
trajectory and require more powder therefore unneeded
recoil will be felt. Most agree that a .54 is ideal
for deer. I read somewhere a long time ago that .52
was the minimum practical caliber for deer and I stand
behind that still. This is the end of my quest for the
perfect deer rifle.
