Hands down, NO question, go with the 45-70.
The 30-30 is a PIP-SQUEAK of a centerfire rifle cartridge.
Yeah, it may have survived for over 100 years, but I for one see NO reason why it does, other than the fact that it is available in the Winchester 94.
The 45-70 when PROPERLY handloaded is equal to the muzzle energy of a 375 H&H magnum; REAL bone-smashin' horsepower !
The 45-70 can be shot in the WEAK factory Rem/Win form which has very LITTLE recoil, although I have NO use for such loads other than putting holes in paper targets.
Recoil of the "magnum" 45-70 PROPER handloads ?
HEAVY, but that just lets you know you are touchin' off something WORTHWHILE !
Dump the 30-30 idea & buy the REAL caliber, the 45-70 ! :twisted: :twisted:
