I just picked up an upper in .350 Legend and my plan is to make it a cast boolit shooter. I'm planning to use RMR Core Lead (12BHN or so) gas checked and PC'ed. Sized to .356. I have the Lee 158gr SWCGC mold, the Lee 158gr RFNBB, and will soon have the Lee 200gr RFNGC. Not sure the SWCs will feed but I figured its worth a try. I have Lil Gun, W296, and AA1680 among others. Does anyone have any experience with any of these boolits in the .350L?
I also have a few j-words to try but, like I said, I'd really like to make this one a cast gas gun. I'm getting good performance on paper with this alloy w/PC. 2300fps in both 6.5 Grendel (126gr FN) and .308 (208gr FN) with no leading. I'm sure those will keep enough velocity to expand out past 250 yards (and you can't see that far where I hunt).
Any insight would be greatly appreciated!
