Looking at putting together a rifle in 22BR for shooting targets out to 100-200 yards. Can anyone give me some advice on barrel length, twist and bullet weights. Thanks for your info. runningbear.

A 14 twist should stabilize bullets up to about 55 grains.

My .22 BR has a 1 in 12 twist, and although it shoots fine with 40 gr bullets, the hoped for accuracy with 60 gr bullets wasn't there. Since bullets heavier than 55 gr can't be moved as fast as I'd like them for live varmint shooting I'd use a 14" twist, and shoot 50 to 53 gr bullets. Heavier bullets don't show any benefit in improved accuracy that I could ever see, out to 300 yards anyway.

22br
Shilen 1-12, 22 BR, mounted on a blueprinted Remington 700 ADL short-action. Favored powder is H322, 53 gr. Sierra hollow point, flat base #1400, seated to touch, 205 primer, Lapua brass. Chamber is a .251" fitted neck, loaded round neck dia. is .248", neck walls outside turned to .012" thickness. Had some nasty pressure problems show up real fast ( hard bolt lift & cratered primers), as I approached the max powder charge, not a case of " a little at a time", backed off 1 full grain, end of problems & that is also the most consistantly accurate load/ 5 shot groups will hold 1/2 moa or slightly less at 200 yd. Barrel erosion is verifyably less than with the 22-250's I've had, as seen with my "Hawkeye", and while the 22-250's were accurate ( Hart & Shilen barrels), the 22BR will outshoot them everytime. One of my favorites. P.S.: Located 12 miles South of Pittsburgh.

22"-24"
14 twist
45NBT's and 52gr Bergers will cover you from varmints to targets and all points between.
Using good components and fitted full length sizing dies you can expect accuracy and 3700-3800fps from the Nosler 45's and same for 52's at around 3500-3550 fps. Of course I'm guessing regarding the actual accuracy nodes but these have been fairly consistent for me.
You could kill an elk with this thing.
Single biggest piece of accuracy advice, "set your fireform headspace for solid crush-fit. GREASE your lugs and PALM the bolt closed, hard."
