Don't know about the best, but my favorite lever rifle would be the original ported barrel guide gun
loaded the 400 gr. Speers in it over 53 gr. IMR 3031
It popped on both ends but the barrel porting helped on the back end.
Don't know if they were all like this one but it was amazingly accurate, zero'd at 120 yds.
1st two cloverleaf, then third shot after zero.
ya!
