(End Of Data)

Seeing significant high pressure signs - smiles, flattened primers and headstamps. Loaded over 100 of these on my Dillon, but after shooting about 20 rounds, I decided brass was looking too stressed. I'm going to back down to 8.0/8.2 grains of Longshot with same bullet, primers, brass OAL etc. next. I'm hoping to achieve ~1250 - 1300fps with a 180 grain TMJ bullet.
