Looking for data for the new 130gr HPBT in a 264. Specifically interested in IMR4350. TIA

I used basic input based on data in the post, let me know what needs to be changes like barrel length, cartridge, AOL and I can recalculate your load.

Thank you! Bullet weight should be 130gr. Barrel is 22". Who is the bullet manufacturer? They have different ballistic co efficiency. I can load particular profile to get better data.

Well, looks like this is newer bullet and Quickload has no profile for it. Sierra does not publish needed dimensions to build reliable profile, so I can offer what Quickload has at the moment - 140Gr HPBT, 22" barrel. Use at your own risk. ________________________________________________ Cartridge : .264 Win. Mag. Bullet : .264, 140, Sierra HPBT MatchK 1740 Cartridge O.A.L. L6: 3.340 inch or 84.84 mm Barrel Length : 22.0 inch or 558.8 mm Powder : IMR 4350
Predicted data by increasing and decreasing the given charge, incremented in steps of 1.0% of nominal charge. CAUTION: Figures exceed maximum and minimum recommended loads !
