Wanted to do some scope work the other day and play with the Garmin. Upon firing the first group I realized my groups kinda sucked, but my load was rather anemic. Reworked the load in the new brass I just got and picked up nearly 250 fps. This will do. 223 with starline brass, 8208, and a rmr 75gr bthp. I'll try this load at 1k in a few weeks
