COAL with 140 vld is 2.990, .020 jump
147 is 2.945, .060 jump
The 147 shot good anywhere from .020 to .060 that’s why I went with the .130 on the new rifle. It will have a Wyatt’s box and BDL so I will be able to run the 140’s at .010-.020 and fit in the box.
ES and SD with H1000 and RL 26 was under 20 ES and around 8 SD if I remember.
I developed the RL26 load last winter in 5-10 degree temps. This summer I left the rifle and some ammo in truck all day with highs around 95-100 and only gained about 15 FPS. This has been typical for RL26 in everything I have tried it in...7 mag, 7 saum, 6.5-284, 6.5-06 AI, 6.5 saum very stable across a huge temp swings. But I don’t run compressed loads or mag primers, maybe that helps.
