Thread: 450 bm

Hi HNK 770 ; I see u in Papamoa. Broncos Outdoors has Red Dot , which seems to be a really nice powder to use for sub loads in my 45/70. There is an American article” Leveraction sub load data” off the top of my head which has a lot of data on sub loads for 45/70 with lots different powders . I know it’s not the same caliber as the 450 Bushmaster but there might be new info on that site ( I can find exact name to google once I get home) . For Red dot I’ve ended up with 12.5 gr with Hornady jacketed Sub x 410 gr & 11.5 gr with hard cast. You probably know ; start loads slightly super sonic with NO Suppresser on & carefully work down. Keep checking the target paper to make sure the projectile is stabilizing & punching thru with a nice round hole. If I’m not mistaken I’m not far away from you & can lend u a chrony if u need
