Help in identifying a powder

[FTRinTexas]

Need some help in identifying the powder from a pulled rounds: Have a 330 Dakota with a brand new Bartlein 25" barrel. Powder weight is 82.3g. The powder is extruded grain (cylinder) like Varget but longer and larger diameter than Varget and closer to IMR 4350 in length and diameter. Velocity was chrono with a Labradar at 2950, 2949, & 2955 f/s. The three shots were cloverleaf at 100 yards. Temperature was 92 degree, 29.90 in Pressure and 50% Humidity. Bullet was a 210g Barnes Tipped Triple-Shock X (TTSX). I would like duplicate this load for a elk hunt in a couple of months.

How old do you suppose the loaded rounds are? Can you post a pic?

Never try to guess. It could be a blend.

I’m with Dusty on this one. You’ve got your chrono data. Work up a load to that level.

There's nothing wrong with guessing as long as you sanity check your answer. It will probably be easier to just try to duplicate the velocity with an appropriate powder.

Fertilize your yard and move on.

Those are the only 2 powders I would care to guess.
