Usually the slower, H4831 alike

Powders work the best. Accuracy no one can predict. Velocity over 3000fps should be achievable, even thought the 26" barrel may be a compromise. The 6.5/06AI is often a winning cartridge in 1000yards Benchrest, so sky is the limit.

Slow Powders

My father has one with a 25" barrel and we get high 2900's to low 3000's chrony'd 10' from the muzzle with H-1000 and superb accuracy - 0.500" 3-shot groups at 100 yards. This was with a Hornady 140 gr. SP, not a match bullet. We have never shot any match bullets out of his rifle but it is an accurate cartridge to say the least. Viht's N-170 also worked well with the 140 gr. Hornady SP. Hope that helps.

I would agree with these velocity expectations.

I have tested some 6.5-06 AIs that would get near 3100 fps with the 140-142 gr bullets while other would only generate around 2900-2950 fps.

Roughly speaking, the average will be around 3000 fps with top end loads. I have found best accuracy to be in the 2950 fps range for most rifles but that is certainly not the rule.

First rifle I ever built was a 6.5-06 AI and flat out loves the 140 gr A-Max loaded to 3050 fps with Rl-22.
