My results from testing RL 26 in the 280 Rem.
I wanted to get an idea of each bullet weight for RL 26
Ruger No 1-A 22" barrel
Norma brass
Rem primer
Temp 60 degrees
Pro Chrono set up at 10' from muzzle
All bullets were .005 off the lands
I fired two shots for each bullet weight.
Two minutes between shots and 5 minutes between each string.
I worked up to these loads, and I consider them a max hunting load for my rifle.
Absolutely no classic pressure signs for any load listed here.

The 175 load/speed is steep and I will reduce it by 0.5 to 1.0 grain.
Everything but the 120's made a nice little same poi cluster.
