https://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/11468173/Re:_Testing_RL_26_in_the_280_R#Post11468173 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.
Nosler 120 BT RL 26 -- 65.0 grains 3,252 3,236
Nosler 140 BT RL 26 -- 63.0 grains 3,122 3,144
Nosler 150 CT/BT RL 26 -- 62.0 grains 3,051 3,072
Nosler 160 AB RL 26 -- 61.0 grains 2,996 2,959
Nosler 175 Partiton RL 26 -- 59.5 grains 2,873 duplicate
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.

Yowza. He's running the 175 about the same speed I run a 139 BTSP with 55 gr of IMR4350. Those are 7mag speeds. Got to be some pressure there.

Yes, and explained that I loaded it down. The speed told me I was high pressure, no doubt.
I went ahead and listed that load as a reference to not go there.

Shot the 280 Rem today 24" KS C LH Rem Cases Rem 9 1/2 Primer. RL 26 powder. 3 shots at 100 yards, 10 F 10 plus wind, 162 Gr Hornady A Max. Rifle has short throat and tight chamber. New warm battery in chrono. 1 shot each load for velocity. 58 Gr RL 26 3 @ 3.5" 2933 FPS 58.5 GR RL 26 3 @ 1.1" 2967 FPS 59 GR RL 26 3 @ 1.83" 2985 FPS may have pulled 1 shot 59.5 Gr RL 26 3 @ .47" Wow 2998 FPS 60 GR RL 26 3042 FPS 1 shot fired for velocity. Easy extraction no ejector marks Velocitys seems hot going to shoot 59.5 Gr load more with same cases and see how primers and case life is. Initial test shows promise. Barrel mounted Magnetospeed chronograph, usually shoot 3 for groups and 4th for speed. Then go to 4 shot groups to see if group holds.

Yes need to check chrono on a different day. Suspect it was fast, or sun interference. Would love some one run the load thru Quick Load and see what pressures are estimated to be before I shoot the load again. Target sure shows what gun likes and doesn't. Bottom right group is with my 270 Win 60 Gr RL 26 with 150 gr N LRAB tried crimp and 1/2 turn in. Shot same load with 150 GR N Part .30" at 100.

Thanks, that makes sense chamber is tight, and short throat with a fast barrel. But its 7MM Rem mag speeds and that alone concerns me.
Case head expansion was normal, and no case stretching, primers looked normal.
