I ran some 190 grain LR Accubonds in my new to me .308 MR with 22" tube this weekend. All loads were at 2.835" to fit the mag. Ran 10 shot ladders with 0.5 grain increments at 300 yards to look for nodes as well as pressure/velocity. I wanted to get to 2,600. I can say that with a 6.5 pound rig all up shooting max 190 grain loads, recoil does get your attention after a bit...grin...
RL-17 - topped out at 2,550 or so. Accuracy was bad, all over map.
RL - 15 -topped out at about the same velocity as RL-17. Accuracy was better. Didn't get to the high node, low node was at 2,450 to 2,500, too slow.
Big Game - topped out at 2,575 or so. Accuracy was so, so. Likely will not pursue further.
TAC - topped out at 2,625 or so when bolt lift started getting a bit heavier. Accuracy was great. Hit high nodes between 2,575 and 2,625. 4 shot group with a 1.5 powder charge range (range may be higher but hit pressure) went into a bit over 3 inches at 300 yards. I am going to play with charges and seating depths but I think there is a good load in here in the 2,600 range -
PS - I can provide charges if anyone interested.
