Hi everybody,
I just picked up a MP 45-270SAA 4 cavity brass mold that was slightly used. The mold is absolutely perfect and casts very uniform .454" bullets from range scrap, 9.8 Brinell.
This is my first go around with the 45-270SAA design, but I've always read good reports on it.
I sized a pile of them to .452" and lubed with 2500+.
I loaded up a bunch with Unique, 2400 and 296 in Starline 45 Colt brass primed with WLP primers.
To test them, I shot them through my Taurus Raging Bull 454 with a TC 2x scope mounted on it. I hung the targets at 75 yards and shot from a sand bag rest.
The Unique group was terrible, the 2400 group was terrible, the 296 group took up 2 sheets of paper.
I wasn't sure if the scope was bad or loose, or maybe I had forgot how to pull a trigger, so i pulled out some of my standard 45 Colt loads with a 275 LFN loaded with 22gn H2400 and shot some of those. That is the target on the right and it looks fairly good for my old eyes with a 2x scope with the sun going down.
Any thoughts?
