139 Scenars are running 2965 with H4350. Haven’t tried any other powders.
Muzzle OD is .725.
1” shank length.

The minimal muzzle diameter is highly debated, but the general rule of thumb is to allow a .050” shoulder for your suppressors to seat against. I’ve had barrels with a skosh less shoulder than that and I’ve had zero issues.

This barrel actually started life as a 6.5 CM barrel. Fell into a deal on another Tikka CTR and sent it back to Shaen for a rechamber. Was a bit hesitant at first, but after studying some Quickload numbers I decided to give it a go. Couldn’t be more pleased.
