243 HSM factory loaded ammo . Other than that just reload . 105s at 3200 fps is hard to beat no matter what case is behind it

Fairly broad criteria. Some really good options already. As mentioned the rave is now the 6 GT, someone mentioned the dasher above. The dasher is very cool but the COAL is a tad to short and feeding sometimes can be annoying without some mag mods. The GT is a tad longer with crazy ballistics. Low recoil, outperforms the 6mm Creedmore, and barrel life is much better than the PRC options. I currently have a rifle being built in the GT but I can spot my shots with a range of rifles. To me, the weight and fit allows me to see impact, and not so much caliber. Not sure what your budget is. If you want something over the counter (box gun), then I would go with a 6mm Creed. Custom I would probably chose a 6 GT.

I will echo the 6 creed comments above.

Great article on ballistic coefficient, sectional density, and G1 vs G7 drag model. In summary, long, slender bullets of greater weight will result in higher BC and therefore better for longer range shooting. 6.5 creed would be my choice. I have two 6.5 rifles but I just hunt with them. Recoil isn't bad. Sierra has at least one bullet with a .7x BC. I haven't shot a 6MM CM so I can't compare but if recoil is similar, I'd go 6.5 for the added weight improvement on BC.

How about ammo?
It sounds very interesting and challenging!

Those are better suited for the 264 WM, 26 Nosler, and 6.5 SAUM class. Recoil on a 6 Creedmoor is considerably lighter than the 6.5, and I’ll a .536 BC at 3100 all day over a .646 at 2750. My 6 in a 10 MPH crosswind at 1K is 6.6 MILs and 1.6 windage. The 6.5 Creed pushing a 140 ELDM is going to run 9.6 and 1.7 windage. BC helps, but it can only overcome so much speed difference. For 1200 and in I’ll take a 6 Creed all day long over the 6.5.

We have moved to subsonic 22lr ammo because it seems to be a little more accurate at these ranges but wind is the real challenge. We are shooting at steel targets with wind flags all along the ranges.
It's crazy fun to hear the hits way out to 300-400 yds.
Good luck.
