bradhall Posted September 12, 2015 Share Posted September 12, 2015 Relatively new to reloading, about 500 rds done in the past year. Trying to workup a new load for 223 with Varget and 69 grain SMK. Shot today with 23.5, 24, 24.5, 25, and 25.3. Best group was with 25 gr at 0.84" at 100 yards. I have a few questions, the more I read the less I understand. 1. Is the lateral string in this group indicative of anything? Shooter, load, rifle etc...? 2. I sat the bullets at the book recommended 2.235". I checked the COAL on the rifle with the hornady gauge and I have a lot of room to go up. Yes I need to use magazines. How should I start to increase COAL? Should I start with the powder charge that worked best, or will that invalidate the results I found at the previous COAL? Link to comment Share on other sites More sharing options...
