For 600-1000 yard target, I think a 90gr vld with a g1 bc of .551, leaving a 22-250 at 2900 fps, will out perform a 185 vld with bc of .549 from a 308 at 2600 fps. How hard would that load be on the barrel? Would 28" be about optimum barrel length? With bullets seated around the base of the neck, would I likely need a long action?
22-250 with 90 gr bullets for LR

I don't have a 22-250 but I nearly bought one a few years ago. I was gonna run 80s but the 90s caught my eye aswell. I had heard they they are hard to tune aswell. You will also need 7T barrel for it to. That could prove to have issues if you wanna run light bullets. Really depends what you wanna do. Take a risk or play it a bit safer and run what you know works.
Thanks gstay, that was a great article! With a 30 inch barrel he was getting 2800+ with a 223 and 90gr bergers. The extra capacity of the 22-250 case hopefully will not hurt accuracy or barrel life too much. Is the only competition class for the 22-250 going to be f open? I don't really want to tangle with those guys just yet, but I do like this idea..
We re-barreled a Savage to a 22-250 ai with a 28" 1:7 twist Pac-Nor barrel shooting 80 grain Matchkings and R-22 fire forming and getting -.5 moa at 100 yards

Yes it has been tried, A friend of mine competed with one at 1000 yards in the 11lb class and it did quite well, I can't remember if it was a AI or std chamber, I'll ask him. I think it was Hoier that commented about the 22 dasher, I think I also would opt for that rather then the 22-250 unless you was planning on a AI. I'ts tough to beat anything off the 6br case.

I agree Wayne. Hard to beat anything off the br case. I was gonna go with a straight 22br but got a deal I couldn't refuse on the dasher reamer. I think the straight 22br would be a better choice. Close to 22-250 performance and burn 10ish grains less powder would be easier on barrels, I would think anyway.
RE: the OPs original question, further history: 'when JJConway first started shooting F-class, he used a 22-250 and 80 gr bullets'. Google is your friend
I have a friend that owns a 17lb light gun that has a 22-250 A.I. barrel it is an 8 twist...when everyone was having trouble getting their 22BRs and Dashers to shoot the 90s...he was shooting consistent .2s at 100 yds at 3100 fps and no blow-ups..it is a scary accurate combo..but too much case capacity...I think the std 22-250 Lapua case would work fine..just go with the 8 twist because of the higher velocity you will get anode above 3,000 fps..

Honestly, I'm not sure yet.
First test was OCW while second test was verification; 24.9gr is definitely OCW with +/- 0.1gr on either side at the same general POI; go another 0.1gr up or down and they are all over the place. In that regard, they are pickier than the 80gr A-Max or 77gr Nosler CC.
I'm no benchrest shooter, but they've shown promise at 2.49" COAL, which is roughly 0.005" jump. The next step is to test seating depths and then verify accuracy at range.
The Canadians, who started F-Class and have long been partial to .22 Centrefires in both 'F' and 'Target Rifle' made a fair bit of use with the 22-250 and eight-inch twist barrels in the early days of the discipline. This was shooting 80s, the heaviest .224" bullet available at the time.
This was also pre the introduction of F/TR and before hot 6.5s really got going, never mind 7s, the standard 2-MOA Bull-ring 'Target Rifle' / 'Match Rifle' target was still in use too.
Barrel accuracy life was found to be 1,000 to 1,200 rounds, and the combination quickly went out of favour once this fact got known.
So far as using a larger case than the .223's (as used in F/TR), the BR is probably the best bet. However, the little 223 will give a 90gn VLD 2,850 to a little over 2,900 fps from a properly chambered (ie very long-throated) 30-inch barrel (~50 fps less with the now discontinued 90gn Berger LR BT taht generates higher pressures than the VLD). So, moving up to 3,100-3,200 fps is not such a great improvement as people think. And of course, as other posts have pointed out, it does put you into the same class as people shooting very much more ballistically efficient cartridges such as the .284 win, 7mm WSM / SAUM!
