First thing at the range yesterday after a couple sighters to warm my barrel, was shoot the reloaded bullet as I previously loaded, going down .001" from the stock .287 bushing on a Redding die. Loaded 5 rds, group tightened up to .700 measured with a steel scale. No unexpected changes in velocity. No pres signs. Enough evidence to load more with the smaller bushing. This was thru the 18" JP.
The last lot of factory Rifleline before the recent drought and the new lot now available shoot similarly from the rifle. Avg fps on the new stuff is near 25fps faster on the magnetospeed. A 10 shot string of the recent stuff had 8 in a .800" vertical and 1.4" horizontal disperstion at 100m with 2 rounds an inch below those. I suspect some of the horz dispersion was from shooting w/bipod off a concrete bench and/or shooter induced from guys shooting tannerite next to us. No difficuly shooting 12w x 30 tall plates at 565 yds. Plate was to beat up to measure dispersion.
