Long Range - Short Barrel -Caliber

[Trogon]

Im running an 18inch 6.5-285 with a 156 berger and just barely getting over 2500fps at a max load. Sounds pretty wimpy, but thats still 700+ yards range at 1800fps limit. So I agree you would need to go up to a long action, drop bullet weight, or drop caliber to meet your 2950 fps criteria.

according to your statement, you’d like a 6.5 PRC necked up to a 7mm

...sometimes called a 7 PRCW.

16.5" 22 creed shooting 85.5 Bergers at 3029
Montana so 22 is legal for all game.
Also have the 6 UM but it's currently a 22". But I'll be getting a 18-20" next year.

A 6.5x7prc should do what you want with 140 class stuff, want the heavies I think it'll be too much pressure.

Something to think about, guys running a 26 nosler(103gr capacity) w/ N570 typically find accuracy just under pressure at 3200-3230 with a 26" barrel. Chop that to 18" and I bet max velocity will be around 3000fps. Back off a grain to be safe, you're at 2950. That's the largest commercial 65mm made. This is why I'm suggesting the 140x class bullets.

A 65saum could possibly do it with rl26, but again high pressure. I'd want 80+ grain parent case.

This thread is excellent. I plan to do the same thing over the next few years. Except, my goal is +2600fps from heavy for caliber 6.5s and I'll probably go 20", but 18" is the only other option I'm considering. There's to many good options in the 120gr-130gr range that should approach 3000fps MV from the same rifle.

I was going to suggest 26 Nosler also - off the shelf, not a wildcat. Maybe the Weatherby 6.5 RPM?
