I was amazed to discover that the lightest bullet (200 gr Speer) gave me the lousiest groups, and the heaviest bullet, the Hornady 265 gr gave me the best. I never expected these results. I know I loaded the 265 cartridge light, so I'm hoping that if I load it just a bit more, it will bring the bullet right in consistently. The final target with the 200 gr Hornady seems to have great potential, but I just about ran out of rounds before starting the test. I was just having fun blast'n when I realized I'd better stop and do some testing... a little too late. I'll load more for next time. Target 5 wasn't bad either. Note that the best results were all achieved with Accurate #9.
BOTTOM ROW, left to right: • Target 4 - Powder: Winchester 296 / Amount: 1.3 cc / Bullet: 200 gr Hornady • Target 5 - Powder: Accurate #9 / Amount: 1.0 cc / Bullet: 265 gr Hornady • Target 6 - Powder: Accurate #9 / Amount: 1.3 cc / Bullet: 200 gr Hornady*. *only 2 rounds fired at target I just noticed something: How come Target 2 used 1.3cc of Accurate #9 and Target 5 only used 1cc? Target 5 was consistently higher! How could .3cc less powder cause the shot to hit higher? How is that possible?
Next time out I take this load: (Powder: Accurate #9 / Amount: 1.3cc / Bullet: 265 gr Hornady) and make sure my cartridge length is correct so the rounds are not under pressured.
