.32-20 Marlin

My old standard load has always been 4.5 of unique. I’ve got a big jug of W231 so I tried it. 4.5 of 231 gives me about 90 fps more and shot nearly identical groups as the Unique, which o have less of. I have some 1680 for .300 blk and have seen it mentioned for .32-20 recently. I might have to give it a try.

Is your arsenal mold plain based or gas checked? This old Marlin has a frosty bore and definitely prefers a gas check. I prefer not to use gas checks but this rifle is so much fun to shoot, I’m willing to get a new mold (rough; I know!) and use the gas checks! This will be my fifth arsenal mold, I think. I really like them!
