I am glad to report that by bumping up my load, the groups did finally tighten up. I think that 60gr RL22 was the best at right under 1" @ 100 yds. with 59.5 and 60.5 doing just a little worse (~1.5"). 60.5 was all that the case would hold without compressing the load.

I can't meet Barnes' recommendation for the distance off the lands and still fit the cartridges in my mags. Still trying to develop a load with 130TSX in my A-Bolt .270. Most bullets that I have tried have come in at around 15 rds. I have gone through an entire box of Barnes TSX and still don't have decent groups. This last batch that I have yet to shoot is loaded 4 pcs. at 59.0, 4 at 59.5, 4 at 60.0 and 4 at 60.5 grains of RL22. I tried 4831SC and couldn't get decent groups. Open to recommendations here.
