Anyone here use Wilson barrels

[SCJim]

after three other powders with only mediocre results I tried TAC. Using CCI 450 primers, Starline cases on their 5th firing, Barnes 120 Match Burner bullets seated at 2.20 COL yesterday I gave it another try and had the best groups I ever had with a AR. Wind was 5 - 10 mph gusts full value from left to right. Normally I try and load develop on calm days and practice on windy ones. However since this was more about velocity than group sizes and it looks like that was the calmest day I will have for two weeks I went ahead and shot. With 27 grains I got 2300 FPS average at 12 feet from the muzzle. I will attach three pics from the Shotmarker target which I imported into the OnTarget software. For reference the grid squares are 1 inch. The first is 26.8 grains, the second is 27.0, the third is a composite overlay of the two targets. The group height is only .108 on the six shots. If this was going to be shot at 100 - 600 yards I would stop right here but at 800 + the velocity is iffy for electronic targets after 600 yards so next session I will be testing 27.9 - 28.9 to see if I can find a node with about 50 to 100 more FPS. I will update once I do the next test and try and do some 600 - 800 yard groups
