I've loaded an older lot of 748 in Hornady cases with F205MAR primers, Sierra 100gr BT at 2.130" (.010" off the lands) for a Savage 110 Tactical.
In 1x collet neck sized cases 29.0gr shot a bughole group at 100 yards. In 3x collet neck sized cases 29.4gr shot another bughole group. I worked up in 2/10gr to 30.0gr where I saw evidence of an ejector plunger on the case head, so seemed to be at the limit. Almost every charge weight with this powder and bullet has been MOA or less.
