California's Central Coast Amid The Insanity
A tip o' the ol' hat to Mr. L. Ross!
A month or so ago, I wrote about giving up on the RCBS 30-180-SP, because I was getting better accuracy with the Lyman 311284. Mr. Ross said to keep at it and to use 2400 instead of Unique that I'd been using. (Why the bullets have never seen 2400 has been filed in my constantly expanding The Many Mysteries of Life binder.)
This morning's 50-yard experiment featured the 03A3, the 30-180-SP, and 16.0, 18.0, and 20.0-grains of 2400. The next experiment will a 100-yard, winner-take-all runoff with 16.0 and 20.0-grains. My money is on 16, because it gave a sub-MOA three-shot cloverleaf, but the two outliers opened the group up to 1"-plus.
Also tested were SR4759 and 5744, but they were a waste of powder and primers. I've never had either powder perform to the level that they have for others, so whatever is remaining in their cans is free for the taking.
