[QUOTE="BML, post: 654200, member: 21078"] Point of impact was nearly identical on all 4 groups. 50.0g and 50.5g shot .9 and .8 respectively. It was hot outside so I waited 8-10 minutes between shots to allow the barrel to cool. All my ammo was kept in my bag and in the shade until I was ready to shoot so it all should have been the same temperature when fired. I did get very slight pressure signs with all but the 50.0g. The sun was setting the later I got into the testing so I suppose that could have affected the chrono readings some. [/QUOTE]
