so a while back i bought a factory marlin barrel in 219 zipper so that i could rebuild an old marlin 30-30 i had. The 30-30 was given to my dad and was pretty beat up and the barrel was way loose. The 219 barrel fits almost perfect. it lacks about an 1/8 of a turn when screwed in hand tight so by the time i get it torqued it ought to be almost perfect, then as long as the head-space is good. this gun has some screws with severely messed up heads that are stuck pretty hard so i might have to throw it in the mill and machine them out to get it cleaned up. Im planning on re-blueing everything smoothing up the action real nice and buying or building a nice wood stock for it. Im going to use open sights of some sort whether its the factory buck-horn ones or a aftermarket tang peep or something else im not sure yet. Ill use this gun mainly for plinking and varmits. Im making brass out of 30-30 first resizing to 25-35 then to 219. I haven't got my 219 dies yet but i ran 50 through the 25-35 and i think it will work, it dimpled them a little on then neck but i think it will fire form out. Im hoping to get to work on this and my mauser project quite a bit from now till summer and hopefully get them both operational.
