.270 Win
140 gr Nosler Partition
New Win Brass
WLR Primer
3.280" OAL
55.0 gr RL-19 (This is a MAX load, in the Nosler manual. Work up from 51.0 gr.)
Consistently under 1" at 100 yards, in my rifle.
The group on top measures somewhere just over .400", and is a pretty standard performance for this load in my rifle. (100 yards)
