Oh, that's cool. I'm always debating with myself about which cylinder to use. You'll probably never miss the LR one. I was out shooting mine Saturday. It was cold.
I was using a variety of ammo, the gray box Winchester Super-X, the black box Supremes, and the CCI V+.
I had my NEF .223 slung over my shoulder and was shooting offhand.
The CCI V+ seemed make the gun jump noticeably more than the gray box Winchesters. Accuracy was way more a function of my concentration on sight picture and trigger control than the ammo I was using, proving once again that my guns are better than I am.
Have fun.
