I have the white gold 1-9 twist sorriest shooting rifle i ever owed. Final got it shooting decent 64gr hammer and 60btip. Tryd up to 77s in just about every make! Wouldn't buy another one. Also the mag will only let u run 2.400 long. The lands r 2.550-2.600 with 75 elds. And vlds. Il probably rebarrel it later on. Got a all American 10 twist that shoots circles around itBrowning also makes a fast twist factory 22 250

THIS (see above): Tikka T3x Lite .22-250 Rem 22.4" w/1:8" twist; $678
Looking for a rifle that has a 1:9
twist rate for the 22-250. I want to push some of the heavier bullets (95 gr) to reach our further. Better BC.
I believe the current and common 1:12 twist rate leaves a lot on the cutting room floor as far as the potential of 22-250 cartridge.
Hey kycarl, I have a curtis axiom action on one of my match rifles, and I'm wanting another one. I don't necessarily need the barrel, but might take the package if that's the only option. Let me know what you are wanting for it.I have a very nice custom with an 8 twist? Curtis action..
I might part with it..
Way too slow twist. Pick a 95-100 grain .224 and look at the length of that bullet. If you put the numbers into any app for twist stability you'll see that for 95 to 100 grainers you'll be in the 7 or 6.5 twist territory. 8 would be marginal to unstable depending on its length for 95s. 8 wont stabilize any 100 grain on the market. Sierra even labels the box on their 100gr for 6.5 or faster twist only. I'm working with an 8 twist now...it wont do 100s at all, as in key holes at 100yds. I'm up to 88s but I'm skeptical that it would stabilize a 95.I agree. I'm currently gathering parts for a 22:250AI on a 1:9.5 @ 26" to shoot 95 - 100 grainers.
Figure 3200 - 3400 fps comes out @ 240,000 to 257,000 RPM. The 224 Valkyrie (a name that may not be spoken) seems to derive much of its issues from RPM.
I think 9:1 might be to fast for anything under 100 grainers. 9.5-10 seems to be the number for me for 95-100. 80-90s are probably better at 10:1-10.5:1.
I always try to get my rpms to 230-250k to determine twist for LR. Caliber/rpm is also a factor for me. Bigger. Slower.
My question is what rifling? I'm afraid of the 3 groove for jacket stress.
Anyone ever tried taper lapping? The 22 cal rim fire guys do it. Barrels are cheap so I'm thinking of trying it.
