Day 2 Ruger Precision Rimfire 22 LR with a Yankee Hill QD Brake and 223 / 5.56 Phantom

Day 2 Ruger Precision Rimfire 22 LR with a Yankee Hill QD Brake and 223 / 5.56 Phantom Accuracy testing with few ammunition options.

Comparing 

Winchester Super X                   40gr 1300 ftps  Supersonic

Eley Target                                 40gr 1090 ftps     Subsonic

SK Standard Plus                       40gr 1073 ftps     Subsonic

Day 2 of testing ballistic and accuracy with an oversized Suppressor. 

At sea level, Subsonic is when the projectile is moving below 1100 feet per second

Target is a dot on the paper about the size of the 22 LR bullet. LOL

Eley Target Ammunition. I should note that I last adjusted the scope for SK Standard Plus and you can see how close the Eley Target shoots to the SK Standard Plus's 

To the left SK Standard Plus Ammunition and to the left you can see how poorly the Winchester Super X groups. Super X is kind of what I grew up with as a kid and looking at the results this ammunition would never meet the standard for target shooting competitions. 

Eley Target below. To compete everything should be within a dime or less on grouping which requires a very accurate manufacturing process.

Some people are saying online that the ballistics will be inconsistent or have issues because of the suppressor size. I am just not seeing it be a problem for what I am doing. Everything looks good to me.
