I spent the day at the range experimenting with different ammo and gas valve setting combinations.
I took American Eagle (LC), Fiochi, Remmington and Winchester all in 55gr FMJ to the range today. I shot five round groups at all five settings which was 20 groups for 100 rounds.
At higher settings I found all four breeds to perform unsatisfactorily. As the settings dropped down the groupings overall tightened up. On "S" I shot an extra 50 rounds, I did not experience any FTF or FTE in this position as the manual suggest may happen with out a silencer on the end of the barrel. I found the gas valve setting "1" to be the best overall gas valve setting for the overall best groups in all brands.
Groups were as tight as 1.25" out to 4". Best average groups were 1.5" using AE.
Overall ammunition performance in my XCR in order from average groupings from best to worst was American Eagle, Winchester, Remington, Fiochi.
