A question about Marlin Lever guns

[skeet]

I have a Marlin 1895 rifle that has Microgroove rifling. I like shooting it but can't get any accuracy with Cast Lead bullets.. Tried a lot of loads and none shoot very well with lead..fine..in fact exc groups with jacketed.. And I don't push the loads..just mid range in the loading manuals..I've tried faster and slower ...Jacketed are always fine. Lead sucks. 5 inch has been good groups

The dilemma... I have a chance to get one of the 1895 Cowboy rifles with the old style Ballard rifling. D'y'all think it would shoot lead better than the Microgroove gun?? I'm thinkin it would but don't want to commit to the buy without bein pretty sure. He wants 500 for the rifle(it is like new) and guess I can get 400 or so for mine. I have at least 1500 lead bullets(350 and 405 gr) for the 45-70 and lotsa good powder for it..and want to shoot for fun.. What say you??? I have more than 500 yds in the range out front..fun shooting..cheaper with lead. I missed a coyote a few days ago with it with 350 Jacketed bullets..about 400 yds. But I was close..scared the crap outta him...Well...I like to think I did anyway!! Lotta drop out that there far
