Re: scope for marlin 336
I do not feel that anyone is arguing that the 30-30 can (now) be used as a long range gun with the premium grade ammo currently available. It is is just that virtually no lever action rifle in a 2 piece stock; regardless of who made the gun, is going to be capable as a long range target rifle. Period, end of statement.
The Marlin rifle in discussion is quite a nice rifle, it is a wonderful hunting gun and as such has performed beautifully for putting food on the table. For obvious reasons the Marlin rifles have their "cult" of followers, if it is what you prefer and shoot well then so be it.
