[QUOTE="ol mike, post: 128179, member: 4683"] RT , The 22-250 shot 45gr win white box ammo around 1 1/4" groups during break in.Crazy thing was i didn't have the burris signature rings tightened down. I look forward to moving to colorado [april 1st] hopefully i'll have more oportunities for load developement.The closest gun range is 25 miles away ,or i'd be tuning loads until i needed a new barrel. I wanted to shoot the 55gr sierra blitzking as it has about the best bc of the bal-tip bullets.I started out about one full grain below max w/h-380 and went up in 3/10th gr increments looking for pressure signs.The group was about 1.3" w/6 shots w/ loads from .9 below max to .6/10th gr over max..The .3 gr under max ,max and .3 gr over max shots were 1/2". I've shot groups that were .300 but i don't claim those to be the norm ,i document -ALL- the shots and they round out to .750 give or take 2/10th's. Seating depth and primers isn't something i've played w/alot but when i no longer have to drive 50 miles round trip to shoot i'll start my super tuning phase! Well i'll be talking to ya happy thanksgiving to you .Mike [/QUOTE]
