Good test. I know some folks who will only shoot Core-Lockt 170's because they are completely convinced in their superiority. Looks like I'll be referring them to this test.
I've shot Marlin carbines over the years, and one in particular was capable of excellent accuracy. While the straight stock is probably the better in terms of all around use, the pistol grip is very steady, and has a slightly shorter throw.
I'm hoping to liberate an old Sears carbine from its current owner, who never shoots it. Made by Marlin, its essentially a 336. Having had serious honest use, it makes the model pictured here look right fine, but for some odd reason, I'm really attracted to the little gun.
