6mm-06 powder choice (update from the range)

Speed seems right where it s/b …. My 240 WB pushes 90 gr TGK 3400 fps out of 24” tube with R26. Factor in 3 more inches of barrel, slightly more case capacity and 5 gr heavier bullet I d say it “makes sense”. That is no doubt a stout ( high psi) load.

Remember in 100 -150 rounds you might gain some more velocity (and pressure) so a small charge weight tweak might be necessary. Good Job with that thing.

In my two 6mm Rem AI's I have had good success with H4831SC with everything from 87 berger VLD up to 108 Elite hunters. I used 4831sc with the 95 VLD and it shot very small groups at around 3400 FPS

What twist barrel?

I have a couple 6-06 improved rifles. They are both 8 twist. A guy that used to build a ton of these used H1000 quite a bit and 4831sc. My last load I used was 57.0 gr Ramshot magnum with winchester 25-06 brass, and I still have a stash of 105 A-Maxs. They run right at 3,250. Last time I took it out, I was thinking I might slow it down. They typically hold under a minute out to 600, haven't shot them much beyond that. They are both hunting rifles.
