edit: I was way confused about the weapon. It is actually a Henry H010B, not a Marlin.
A friend of mine has a Marlin 45-70 he uses for hunting and I have offered to introduce him to reloading for it. I have never seen the rifle and do not know squat about it. Waiting now for a response from him whether it is an 1895CB or other.
Not being a Marlin guy and only going from what I have read in passing, if it's not a CB then it probably has micro-grooves and is not a good candidate for castboolits. True or false?
Are Marlin barrels all over the place and slugging a must, or can I make some general assumptions? My common sense tells me, assume equals "ass of u and me" and I need to pound cast the chamber with a fired case and have something to load from/to.
Per conversations with him, he is worried about reloading his once fired factory brass. From my cursory review of google searches, if FL sized with a little common sense (sized a thou or two below chamber dimensions) the brass should last MANY firings and is not unlike straight walled pistol cases (357/44 mag). i.e. they shoot until the necks start splitting. True or False?
I know some pretty lame wonderings, but as usual our search engine here is limited. i.e. "45-70" nets zero/nothing found. So what do I add to that search parameter that doesn't produce hundreds on completely non-related results?
