I have a Ruger #1-V in .22-250 & a Remington XP-100 in .221 Fireball for which I've picked up a selection of Hornady V-MAX bullets in weights from 35-60grs. In the Hornady 6th edition manual for the .22-250 loads using their 60gr V-MAX bullets, there's a note stating "will not stabilize in a 1-14" and slower twist Bbl's". There's a similar note in concerning their 68gr & 75gr bullets not stabilizing in a 1-10" and slower twist Bbl's. My .221 apparently is a 1-12" twist but does anyone know what the twist would be in the Ruger 1-V
in .22-250? I'm guessing possibly 1-12" or 1-14".

I 'bounced' around on their website a bit but I wasn't able to find any of the spec type info I was looking for. It wasn't in the manual that came with the rifle or any other Ruger material I have on hand.
In the Sierra reloading manual I did find some rifling twist info but none specific to the Ruger #1 in .22-250.
Ruger does have a couple of phone numbers listed but no e-mail or online contact, at least none that I was able to find but I thought I'd try here before phoning. It's not critical so I may just go ahead and load up some 60gr V-MAX ant try'em out.
 
Try 'chuck hawks' his website has all kinds of info...Or just google your rifle then throw the words 'accuracy reviews' behind it
 
It is very easy to measure the twist if you have a quality cleaning rod... simply push the jag with a tight fitting wet patch through the barrel and measure how far the rod travels in one revolution in inches.

One revolution in 12 inches is good, one in 14 inch isn't.
 
Unless the barrel has been changed or was a special order, your Ruger #1 has a 1-14" twist. I would still try those 60 Hornadys, they will stabilize in some 1-14 twist barrels. ( My 220 Swift shoots them just fine, it's a 1-14" twist) Keep in mind that velocity plays a small part in the picture as well, so while a 1-14" 222 Remington will not stabilize the 60 grainer at 2800 or so, the 22-250 might just do it at 3400+.
 
Thanks guys I appreciate the input. Eagleye, thanks for the info. I will try the 60 grainers but for my basic intended use for the rifle, whatever gives the best accuracy is what I'll probably stick with. Thanks again all.

Thank you, and Eagleye. I took a look on the Ruger website but didn't find the info. Guess I didn't look close enough. I loaded up some 40gr & 60gr V-MAX yesterday so I'll see what the results are.
Recently I picked up quite a selection of Hornady V-MAX and some Sierra Blitzking for my .22-250 & .221 Fireball. Looking in the Hornady manual after the fact, I saw a notation dealing with stability issues of the 60gr in the .22-250with a 1-14" or slower twist Bbl. I didn't notice a similar concern in the Sierra manual with bullets up to 63gr but there is for bullets above that weight.
Anyway, as I've mentioned, I've loaded up some of the 60grs, so we'll see what happens. Thanks again for the input & info guys. Oh, doemaster, drop the sir. I haven't heard that since I was in army cadets.:)
