For those who shoot the 10 MM and reload, Starline is about to make a run of 10 MM brass. I was there about two weeks ago and the owner told me he was running ten about the first of June. So, if you get your order in they ship without shipping charge and I think 1000 rounds of 10MM was about $170. He will sell the entire run in a short time.
They also are a good source for various other cartridge brass and have 45 ACP +P, 45 Super and 460 Rowland. I buy my 45-70, 45-90, 45 2 7/8" Sharps and 50-70, 50 -90 (2 1/2" Sharps) from them. Check it out.
