faster twist 22-250

[okie]

I recently acquired an almost new 9TW 22-250. What is an appropriate weight bullet to start with?
(Varmint/target types) I have no experience with this twist---I always have shot 50-55 grns through 12 and 14 twists...
I have looked and think around 75 grns??? Thanks in advance, marc

I also have a 1-9" .22-250. So far, I've shot 75 berger vlds, but am going to give 75 amax a try next. Mine has a long throat, and R15 has given pretty impressive velocities

The 75's will probably shoot fine for you but with that 9tw they'll probably be at a reduced BC. The Sierra 69gr TMK would probably make for a slick bullet choice at full BC.

I have a Savage model 12 in 22–250 with a 1:9 twist and I shoot the 69 grain Sierra MatchKing out of mine and it does fantastic.

I built a 22-250 with a 1-7.7 Kreiger barrel for a kid in Wyoming. He shoots the 77 gr SMK in it.
has killed several Coyotes over 600 yds with it.

When my current, 1-14 Twist, 22-250 Rem 700, gives up, the Ghost,..
I'll go with, the Ackley Version ( I HATE,.. Trimming ! ) and a 1-9 Twist, to shoot,.. the 60 gr. NBT's, 65 GK's,
69 MK's, 73 gr. Bergers and 75 gr. BTHP Hornadys,.. Surely, a couple of those, will "Shoot",.. outstanding !
And,. I have, a 6 XC for anything that, I need MORE,.. Range / killing power, for.

69 TMK, 60 TMK, 55 BK. All with IMR 4166 @ max (maybe a smidge over ). Fast and accurate.

what powder for the 69's?

I think there are quite a few powders that'll work well but one of the first I'd try with the 69gr TMK's would be RL16.

The 9 twist 22-250 I had shot 77SMK ahead of H4350 very nicely.
I know the box clearly states 1:8 or faster but I called Sierra and the guy told me the 77SMK was really made to work in a 9 twist.

 

[Tucker65]

I'm pushing 70gr Nosler Rdf's with H4350 @ 3425 fps. It's been very accurate shooting steel out to 800 yards.

good info. guys, thanks for the responses!

B23 is correct with the 75 vs 69s. While the stability calculator may not be a perfect tool for deciding if "your" barrel will optimally stabilize a bullet, I believe the 9 twist is ideal for the 69smk as I use them in a 9 T .224 barrel at 800' asl. In higher elevations (above 4500') the 9 twist will work well with 75s. It's always better to chose the proper twist rather than use elevation for your gauge. An 8 twist is probably IMO the best twist for a 22-250. Getting down into a 7 twist often causes bullet failure. The 8 twist will not cause that issue unless using extremely light thin jacketed bullets.

thanks---got it as a package. came with 9 tw. if i can find the 69's im gonna let my boys burn the throat out on gongs. then maybe a 6xc or 6x47L is going on it

I like to run the Sierra 69gr and 77gr HP with a compressed load of RL17, there short bearing surface allows them to work in slower twists also.

You'll have great success with the 69s
