SCOPE DURABILITY?

[garandman]

On muzzle loaders yes but it's still a time / pressure ( force ) issue .concerning the 308-30-06 the variables were identical. Long long ago in a different lifetime . I forgot the military testing that was done but commercial testing by a few publications were resulting in the same outcome .
My experience with muzzle loaders were different, based on dozens of returned scopes , BUT when this was occurring, muzzle loaders were black powder , had HEAVY hex or octagon barrels and brass , sharp butt hooks .
Not plastic stocked let weight in line stuff .

Same here. My reference as I noted above was (1) an original 1884 TD Springfield cartridge gun and (2) an original 1863 .58 cal muzzle loader. Not the modern creations of today. What I am referncing definitely has a softer "felt recoil" compared to equal weight projectiles and equal weight powder chages of smokeless powder.

Outside those parameters, I have no experience, and gladly defer to others. Within those parameters, see my disclaimer, below: V V V
