I see. I guess they needed something new to charge more for....as if the cooper ones aren't expensive enough.
I don't shoot magnum charges in my .50 magnum anyhow. I just use 2 pellets and a 295 gr. cooper powerbelt.
Last year was my first year with a muzzle loader and now I am addicted. I took 2 shots at deer and dropped them both deader than a hammer so I guess that load/charge will work.
