I use my 45-70 guide gun. Same for my buddy. My son will never know the abuse of shooting slugs. He somehow adopted my 1894 in 44....even after I bought im a 16in Henry in 44. I like the 45-70. 450Bm has never appealed to me. I don't foresee switching but with 2 more kids to go I have to imagine the recoil of the 350L in an AR with a suppressor would make for a pleasant hunting experience for them.
