My 22BR likes the 85.5 Berger
Can you give me some more details on your rifle, load, velocity?
7 twist Bartlein 30" long. Lapua brass. Rem 7.5 primer. 0.060 firing pin. 30.0 Varget. In the lands. Tube stock prone gun.

I played with the 95smk in 22brx this winter and spring. Got them above 3100 and very accurate (see seating test), but it became an unsafe load when it warmed up so backed it down.
The 600 yd target is the 95smk mid 3000's but locked up the bolt on shot #8. Haven't had time to get back to this project as the shooting season started for me (TR shooter). Will retry with 95s below 3000 and 80-90s again this winter.
Here is a 1000-yd target for fun

N150 and the barrel is long. Will have to measure it, but might be 34" and it is at least 32" and its a 6.5 twist

They're finicky in my rifle but there is no denying that they have a great BC - they need less clicks in the wind.
The 85.5 could be driven very fast in my 22BR. So fast that it entirely eclipsed the heavier 90gn class of bullets in ballistics but I struggled to get really fine accuracy out of them.

You can hit 3000fps. In my thread linked above - I have a .100 freebore. You can probably get more powder in there than I was able to and could go a little slower on burn-rate. For example, I could never get enough RL-16 into the case to get top speeds but you might be able to. What twist do you have? You may blow bullets up, just as a warning.

I shot gobs of them out of a 7 twist 22BRI. 3030 fps.with a 30" tube and high pressure using N160. That barrel did make it to nearly 2000 rounds before blowing bullets.
If you have not ordered the barrel yet get a loose bore. I can't say for sure but I will warn you that anything above 300k RPM is gonna probably he problematic. You may get a lucky bbl but I will not personally mess with it anymore. Have about 600 bullets i'd sell.

I tried both H4350 and Varget with 95gr SMKs. No big surprise but varget turned out to be more consistent. 30grs of Varget with an 11 shot string(over 2 days) hitting 2987fps 2 SD/7 ES and a 12 shot string hitting 2985fps 3 SD/10 ES with all 23 shots falling into the 10 ES.
Only problem I'm having at the moment is I'm getting flyers. Small .2" or .3" 4shot groups with 1 that brings it between .5" and .7". So I'm going to tweak it a bit to see if I can get all the shots to fall into the group

EEK, that's cooking. I was getting bad pressure on Varget at 28gns!
I have had persistent fliers with the 90 VLD and the 95SMK that no amount of tuning seemed to get rid of. The 88ELD and the 85.5 Hybrid are better about not throwing one out. I was able to drive the 85.5 so much faster that it completely wiped out any advantage the 95SMK had out to 1000 yards: http://forum.accurateshooter.com/threads/my-new-22br.3981971/page-3#post-37711564 - 3200fps. I'm sure RL-17 would have given even more speed, but my gun doesn't like it. You may find you can get a lot more speed with your long freebore and a powder like RL-16 or 17, if your gun likes it.
How fast are you shooting the 85.5?

i think my 22br is a 12T. Kind of a waste -- Good thing its a cheap barrel i wont cry about throwing away. i guess i can cook some 4000 fps woodchuck loads out of it. would like to try some of these heavier bullets - and i do have a barrel coming- mabie this will happen. Sorry couldnt help but looks like youre on the right track. Thanks
