I finally got around to getting some load development done on my new hunting rifle in 260 Remington. This was a Stevens 200 that I have replaced everything on it except for the bolt and action. The barrel is a 24" ER Shaw .260 Rem chrome-moly sporter from the very first group buy.
My tests were with the following components:
Once fired Remington brass
CCI BR2 Primer
IMR-4350
Sierra 140gr GameKing (with .020 jump) and Berger 140gr Hunting VLD (with .015 jump)
I tested 4 loads each of 40.5, 41, 41.5 and 42gr on each bullet at 100 yards. Here are the results of my best of each:
Sierra 140 Game King with 42gr IMR4350 (velocity: 2738, 2735, 2738, 2740)

Berger 140 Hunting VLD with 41gr IMR4350 (velocity: 2639, 2666, 2653, 2674)

The Sierra was grouping around 1.5" on the first three loads and then at the 42gr load it became spectacular!
