Finished fireforming my initial 100 243 AI cases today at the range. I actually kept a few of the targets and took some pics of them since I think I have this pic posting figured out.
I made a tool from 1/8" brass rod and a couple of bow sight pin clamps for determining OAL.
Next step is ladder testing to determine powder charge to go with the 95 g nosler ballistic tips.
I'll keep you posted as to the progress.
picture quality is lacking but its a dime and 5 shot groups at 100 yds. Zero not dialed in yet due to garbage loads was just looking for grouping.
