RE: Powder question?
One time about9 or10 years ago, one of my brother-in-laws came down to W. Yellowstone to elk hunt with me. He forgot his rifle. So, being the good guy I am, I loaned him my .300 win mag and pulled my ML out of the moth balls from back in good old Illinois.
So, I was shooting a .50 cal hawken type with 350 gr. TC maxiballs. I hadn't even looked at my powder in a couple of years since I had moved up from Oregon, so I pulled it all out and went out to "test-fire" prior to our elk hunt.
I set up a target along the logging road (on the way to our hunt loc.), and fired one shot at50 yards, at a paper plate stapled to a tree. The wind was howling so bad and I hadn't shot in a couple of years, that when I pulled the trigger I not only jerked it, but bucked at the recoil as well. Needless to say you could still eat off that plate without any leaks.
I hit the plate nearly dead center on the second shot, and called it good, unfortunately for me I didn't see an elk within 50 yds that day.
