[QUOTE="entoptics, post: 1746581, member: 104268"] Well...Reset the headspace using my brass collection. Twice actually, as I let Devcon go up through front action screw hole, into where the bolt head cams around to lock, and had to pull barrel again to chip/scrape it out of there...:mad: Pretty much screwed the pooch with redneck headspace tricks. I fired several rounds, and my new base to shoulder datum is almost 10 ten thousandths shorter!:( Just kidding. It worked like a charm. My caliper has a 0.0005 digit, which I don't trust, but if I did, it appears my new BTSD is averaging 1.920. Brass fired previous to my amateur gunsmithing is averaging 1.925 to shoulder datum. In other words, new is same as old within error, but perhaps just a smidge shorter. :cool: Rifle shoots fine, and my bedding may have improved things. Too early to tell if it's its a lot of improvement, or just a hair. Testing started with a couple "mehhh..." groups (using reject concentricity reloads) and ended with a couple "Ohhh??..." groups (with my best loads I crafted/culled for hunting).:) Planning to do a little bit of re-development of loads with new conditions, but otherwise happy with the job.
