300 WSM + RL26 load request

[Ckleeves]

Just finally got around to getting some data on the RL26 205 eol combo in one of my 20" 300wsm rifles. Rifle has about 100 rounds on it now.

ADG Brass. RL-26. 205gr Berger EOL. 3.050 COAL right at 20 thou off lands. Defiance XM+ with 20" Proof Carbon Bull. Spun up by Fritz at BCC.

65.0 - 2608
65.5 - 2625
66.0 - 2669
66.5 - 2697
67.0 - 2706
67.5 - 2754
68.0 - 2759
68.5 - 2803
68.8 - 2812
69.0 - 2834
69.3 - 2839
69.5 - 2873
69.8 - 2887
70.0 - 2887
70.2 - 2894

That's some impressive speed out of a 20". I just broke into a new lot of RL26 and it's giving 2907 average with 66.5 gr with a 205 out of my 24". Accuracy is awesome and I had a ES of 4 fps across a 5 shot group while verifying zero.

@Ckleeves Thats some good speed for that 66.5 load at 2907 with ES of 4!

I'm happy with it for sure on these speeds so far. Glad I went 20". Loading up some 5 round test packs to shoot for accuracy this week. Forgot to mention it wears a TBAC U7. Not sure if that matters for most, but a data point none the less. My chamber is also throated out a little further for the XM+ action and those mags.

I did see slight extractor marks on the 70.0 and 70.2. Bolt lift was fine still.

Had a quick few minutes to load a few and run down to the range. Was windy and it was moving the wood benches around but managed to get some data. Will have to head back out in better weather and not being so rushed. Will also need to confirm these and then load up some more for 5 round groups. Then start stretching it out a bit.
