Doing testing on copper and brass
Friday, July 23, 2021, 12:16

Both solids and HP’s. I have found this, and heard from others, they loose power, as I believe the gases goes around the projectile. I’ve shot some into a bullet trap, and the rifling grooves are barely evident compared to jacketed soft point bullets. One gentleman said they feel like a lighter load.
Just what I have found. Performance wasn’t great either. The copper HP’s came apart easily, brass ( rifle only) did not open at standard speeds. I will say the solid copper (410 grains in 454) were really accurate.
I like 300 sierras for tough animals. Used on moose, bison, hogs and bears. Then the Swift HP’s if you want them to open up but stay strong. Just my .02c worth.
