[QUOTE="Kansaswoodguy, post: 1099365, member: 83267"] I shoot a little tighter groups at 100 yards with the 55 gr bullets but that could just be in the head. I shoot a lot of the 75 gr HPBT Hornady match bullets CCI 400 primers around 23 gr IMR 8208 XBR have shot many sub MOA groups at 400 yards with that load but they are not as tight at 100 yards as the 55 gr vmax tend to be but the 55 gr fall apart at 400 yards with the wind kicking them around. I'm in the process of building an AR-10 in 6.5 creedmoor just got the Krieger 26" barrel with headspaced bolt from Fulton Armory the other day absolutely cann't wait to get it assembled and try it at 1000 yards after some load devepment. On this build I am seriously considering using Locktite 620 between the upper reciever and barrel extension because my fit is a little looser than any of my other builds have been most of my 223 fits have been a nice snug fit with no barrel nut installed this one has a couple thousands play I even looked on Brownells to see if the had a upper reciever lapping kit like they do for the AR15's. Crazy what we will do chasing that last little bit of accuracy out of these guns but that's half the fun. :) [/QUOTE]
