Wow, what twist rate are you running?

I've ran 7.83 and 8 twist...had great results with both.

Here's an old ladder shot at 600yrds.....Varget, Sierra 107's, Russian primers.

Looking forward on your H4350 results. Enjoy your 6BRA. The 6BRAI is my preferred choice for registered IBS longerange benchrest competitions.

I have a light gun and heavy gun 6BRA benchrest rifles. They have identical chambers using a Pacific Tool and Gauge reamer designed for a 103 Vapor Trail. Both use IMR 4895 at 29.9 for the Vapor Trails and 29.3 for Berger 105 Hybrids. Both are seated into the lands with a square mark on the bullet. Both are capable of shooting 2" inch groups @ 600 yrds when I do my part. I've tried Varget but never generated the accuracy of the IMR until I got up to scary pressures.

In a slow 14 and 12 twists with zero freebore, the 55g Nosler loves H335 and AA2230 with rem 7 1/2 primers at 3900 fps, with 60g at 3800+....tiny bug hole groups abound and 3/4" at 300 is not unusual at all.

AA2495 instead of Varget, 8208, and 4895 will add a LOT of throat life when running 105ish weight bullets.

Beware that some lot# of the Hornady bullets run .2440 on the pressure ring and std throat dia is .2435. The bullets get pushed way back in the case when you have a lot# of fat bullets.
