in a 22-250 with a twist rate of 1 n 9, I know a 70gr vdl should work great but my question is will a 50 gr bullets stablize the lighter bullets need a 1-12 or a 1-14. I want to shoot the 70gr but I would also like the 50 to if I can and have a zipper round and for varmints.

Friend of mine has .22-250 with 1 in 9 and he shoots 50 to 70gr with no problem.

I have shot 50 grain in a .223 with a 1-9" twist and they worked fine.  I have also shot 55 grain in a 1-7" and they shot fine as well.

OKay I'll give them a try and see how they work. I just didn't know if they would spin apart in that fast of a twist.

I know that used to be a concern, but with current bullets, have not heard or seen that happen for quit a while.  2 guys at our church shoot .223 with 50gr Nosler bt's.  They both have 1 in 9 twist barrels and both are pushing them around 3200 with no problems.

Brother in law gave me a box of 69gr sierra, but I don't think I will be able to get them to stabilize in my .22-250.  My twist rate is 1 in 14.  Believe the box suggest a minimum of 1 in 9 to get them to stabilize.

BD, what kind of rifle do you have?  My brother in law gave me a box of Hornady 68 gr bthp.  My current .22-250 has a 1 in 14 twist so I know they won't work, but now I thinking about getting a savage with a 1 in 9 twist.  Curious to what you have and how it has worked so far.

I just got a savage LRPV in 22-250 with a 1-9 twist. I just picked it up yesterday so I have not got to shoot it yet. I bought some 55gr VLD's to try. I would rather shoot a 69gr bullet but just found the 55 so why not try them. I'll let you know in a week or so how they work out and I should have other also. From what I hear the 69/70 gr work great in the 1-9.

Brother has one of those in single shot.  Not sure if he has the 9 or 12 twist.  I was looking at savages varminter low profile.  I have read/heard the same thing about 69/70 gr in the 9 twist.  Waiting on your results.

10-4 SD. The one I have is the left port right bolt single. This thing is built like a tank and just about as heavy. I'm pumped about getting it out and testing with it. The trigger is very very nice and just under 1 pound.Takes a little to get use to but will be fun to use.

In general a 1-9 twist in a .22 centerfire will stabilize bullets up to 70 grains or so. A lot depends on the individual bullet, and a lesser amount on muzzle velocity and the elevation where they're shot.

The newer plastic-tipped bullets are also longer for their weight than standard soft-point or hollow-point bullets.
 
Today's bullets are so well balanced that a 1-9 twist will shoot about any .224 bullet reasonably well. I have even had great luck with 40-grain bullets in a couple of 1-9 .223's.

Nice thing about that gun is that if you get stuck or need a pry bar, the barrel will do double duty.  Wink
