Update after trip to the range.
M-100 in .308 Weaver 2.5-8x scope--> 150 gr. Remington Corelokt factory ammo. --> 1st three shots, one ragged hole at 50 yds. (2" low, 2" right), moved to 100 yds, 3 shots inside 1"(2 touching) made adjustments to zero at 1.5" high at 100 yds... 3 shots covered by a quarter @ 100 yds. I'M A HAPPY PUPPY.
pre '64 M94 .30-30 open sights--> 150 gr Remington Corelokt Roundnoses --> 3 shots into 4" at 50 yds, struggled to keep it on paper at 100 yds(my fault, never shot more than a .22 LR with open sights and never farther than 50 yds.... It will make a good pig gun up close, but I don't feel comfortable past 50 yds. I may use it to work on my stalking skills! I do have to say it kicked like a mule!!! by far the .308 was much smoother.
I may have to see if my uncle will sell me the .308w. He did say he wanted to trade it for a .243w for his youngest boy. I'll have to get a different scope. The one on it holds zero ok, but it is the ancient type weaver mount that the adjustments for zero move the scope, not the reticle. It'll do for now.
All said and done, I'm a happy puppy, at least I get to go hunting!
