jbell, had a chance to hit the range today to do some ammo testing (Eley Match), winds were light, which has been highly unusual for my area. I shot with my 2500X rifle, Shilen barrel, Harrell's tuner, Bix N Andy trigger, RoTex Stock, on a one piece PQP Lite rest.
I've attached two targets, using the first 4 bulls on the top target and the 800/900 (top 2) bulls on the lower target. Winds picked up for the last two bulls on the lower target and opened up the groups a bit.
I measured from edge to edge of the brown ring, subtracted 0.223 from each value, then averaged all 6 targets. The group average was 0.447 and the best group was 0.279. No cold bore on these targets.
Let me know if you need more info? It's been awhile since I have submitted any targets.
Thanks,
