Quite a while back I cast and fired some 44 mag loads using Trailboss, unique and w296. If I remember correctly I used the TB 70%formula. Unique was 7 gn, and w296 was a near minimum load. All were pushing Lee’s 430-310RF I believe.
I shot these from both a 14” Contender and a Ruger 96/44, and maybe my 1894 Marlin was in the mix as well.
I don’t own a chrono yet, but the W296 loads were a much higher velocity than the fast powders according to the load data.
My question is why is the point of impact so much higher with the slower velocity fast powders?
In my mind I’m trying to attribute that to muzzle flip caused by the quick burn rate.
Any thoughts on this?
