I have now ran five different ammo types through my Tippmann. I am not the most skilled plinker around so my groups are not super tight, but I am consistently not tight so it is comparable. The groups I will list are at 25 yards, sitting at a bench supporting the gun with my arms.
1. Federal Range Pack 40 Grain 1200fps. No issues (since putting the Tippmann hammer spring on my LaRue trigger), 25yards 20 rounds .75" group with 1-2 1" fliers. 800 rounds total
2. Remington Thunderbolt 40 Grain 1255fps. No real issues but the bolt has some inconsistent cycling "feel" to it, 25yards 20 rounds .75" group with 5-8 1.5" fliers. 1000 rounds total
3. CCI AR Tactical 40 Grain 1200fps. No issues, 25yards 20 rounds 5/8" group with 1-2 .5" fliers. 900 rounds total
4. CCI Standard Velocity 40 Grain 1070fps. No issues, 25yards 20 rounds 5/8' groups, no noticeable fliers. 250 rounds total
5. Federal AutoMatch 40 Grain 1200fps. Not my favorite, I have had one fail to feed and some unpredictable fliers, 25yards 20 rounds .75" group with 5 1-2" fliers. 250 rounds total.
CCI AR Tactical, 20 rounds @ 25yrds:
