22 Creedmoor, which bullet for tack driving accuracy, for Fox shooting.

[Hobbs]

Hobbs, I don't have creedmoor but do have an 8 twist 22-250. I run 69 gr. Sierra HPBT with H380.
If you like groups without paper between shots try that combo in your Creedmoor. Adjust powder charge accordingly for the bigger case.

That's the type of groups I always look for. Nice shooting

Unfortunately H380 isn't REACH compliant so it's not available here in the UK, but the TMK's are

Hobbs, Like I said I don't have Creedmoor but I do have 35 years experience with the 22-250. I have found regardless of barrel twist, I always got benchrest accuracy keeping loads at around 50k psi and not running at max pressure. This may translate to the Creedmoor too, so it's just another data point in your search.
Another great powder that was recommended to me by Shilen rifle barrels was Reloader 15. Is that available in the UK?
