First load will be some basic testing.

Benchmark with 303 HC pittmans

Start at 88 gr up 93 gr. 2 shots of each.
So will check out velocity and accuracy. See what happens.

Don't want to clog up with different powders. 1 powder at a time which will give me more times to hit the range
 
Got my weather window guys. Just did a quick 2 shot load test to see potential. I don't know what you call it but just checking potential.
BENCHMARK WAS THE POWDER TODAY

This was so much fun. I need to ask dumb questions here. Do Barrels speed up like center fire rifles? Like at the 80 to 120 rounds down the tube to become stable speed wise?
