96gr. RL25, and a 178gr. A-Max netted me groups of .695
100.5gr. Retumbo and a 178gr. A-Max netted me groups of .5
92gr. RL 22 and a 178gr. A-Max netted groups of .650
93.3gr. IMR 7828, ans a 180gr. Sierra SBT shot groups of .6
96gr. RL25 and 180gr.SBT yielded groups of .920
That should be enough to keep you busy for a while!

Re: 300 ULTRA loads??

Lots of data posted already if you do a search for the powder, bullet, cartridge etc, etc.

I'm using 96gr RL25 and a 178gr A-Max at 3300 fps.
96gr RL25 with a 180 Scirocco, Nostler BT, Nosler BST at 3250 fps.
85gr RL25 with a 220 SMK at 2900 fps.

Pressure was a bit lower with the 178 A-Max so 3300 fps was attainable at under 65,000 psi on the Oehler 43. Accuracy was best with the A-Max also.

These loads were all max loads (65k psi) in my 26" barrel, so work up to them.

Hey smoak I'm sending you some loads for 300um reduce by 5% and work up! These loads work great for me (sub-min.).
