RE: lever or bolt action, why one or the other?
I've hunted deer with a gun and bow for over 35 years. I have been a gunsmith for 27 years. I've used levers, pumps autos, and bolts. I will NEVER use anything anymore except a bolt. The main reason is that a bolt will not malfunction as the others. I can't count how many guns are brought to me that failed "at the wrong time". I had a M 742 do it to me before. Never again!
Guys in my hunting party used to use autos and pumps and all but one has converted to bolts. I've clearly noticed that since they converted they became much better at killing their deer on the first shot. It's amazing what the quick 2nd shot can do to someone.
As far as levers....Leave them alone for 2 reasons...Safety (exposed hammers) and dependability again. Just my 2 cents from and endless number of repairs and watching my hunting buds.
