Has anyone had any experience with "SNS" cast bullets.
I ask because my experience has been all BAD. I am loading the SNS 250gr. RNFP bullet listed as .452" diameter. The bullet actually measures closer to .453" diameter.
I am trying to work up loads for a Henry Big Boy with these bullets and having no luck at all. I have tried loads using Unique, Winchester 231, Accurate no. 5 and Accurate no. 7. The best groups, if I can call what the targets look like groups, run at about 5" and go up to 8" to 9" at fifty yards. I am shooting of a bench with bags and the rifle is scoped.
Yesterday I decided I had to try a couple of the 45 Colt factory loads to see if the rifle is junk or the bullets are junk. I fired Winchester 250gr. lead RNFP factory ammo and the groups ran 1" and 1 1/2" center to center at fifty yards. I didn't consider that too bad, as I was rushing it a bit. Then I fired Federal 225gr. jacketed soft point (RNFP) factory ammo. The first five shot group measured 3/4" center to center. the second group had 4 rounds of the 5 in one small ragged hole barely larger than the bullet and I put to fifth round 1/2" to left of the other four. I considered those groups great and confirmed the Henry can shoot extremely well with the right ammo.
What in the world is wrong with the "SNS" bullets or loads?
