proper rate of twist

[sbowers5]

Sam, this question is for you i am going to start on a new rifle and it is going to be a 22-250 that will have a heavy barrel and will be used for varmit hunting and i would like to have your opinion on the rate of twist you would prefer.

I know you're waiting for Sam to answer, but I know that the "optimum" rate of twist will depend on the weight of the bullets you intend on shooting (and on the caliber, but you've already mentioned that). A heavier bullet will require a faster rate of twist.

As Just a car said, with a small caliber like 22-250 heavier the bullet, faster the twist. long skinny bullets are not the stable so need to spin fast. Not sure on the exact rate tho, hope sam can help you.

well i can get barrels form 1 in 9 to 1 in 14 rates of twist but i would think that for varmit hunting you would not want to use anything much over aboput 55 gr. bullet. of course thats just my opinion. thanks for the comments.

You dont state whether this is a project or you are buying a new rifle.If it is a new rifle the two I checked were Savage and Remington and only Savage has a 1in12" twist.Remington comes in the standard 1in14" twist which is fine but limits you to 50gr or lighter with the exception that you can possibly use a 55gr flat base bullet.The savage should be good up to 62gr hpbt.Or polimer tip.As to a heavy barrel,if you are only varmint hunting,a heavy barrel will not help that much unless you are hunting pd,s and doing high volumn shooting.Even then I would go for a fluted barrel.Before I decided on a .22-250 I would look into a .204 Ruger which will perform with the .22-250 using 40gr bullets in both out to 500yds.In fact it does better.Where the .22-250 may be better is with heavier bullets and longer range.If long range is your desire,get a decent scope.At 500yds I stick with 6.5x20,s or 6x24 with 50mm optics and good sunshade.He didnt do it but I invite other coments and I know he will apreciate it.Some of you are wiser than me. sam.

Looking around on the internet i would say the tighter the twist the better. I am looking for a varmint gun myself, probably either 243 or bigger though. But, in smaller calibers such as 223 and 22-250 what i read made it sound like it wont hurt to get the smallest possible, 1 sight mentioned 1:7, basically tighter the twist the heavier bullet you can use i guess

sam i am going to built this rifle on a 98 small ring mauser and i had not planed on using anything much larger the 55 gr that is why i was wanting your opinion on the rate of twist.thanks everybody. and sam i'm pretty much set on a 22-250

That is true"BUT" for longer barrel life,more fps,and less heat,if you are not going beyond 500yds and dont use over 'about' 60gr bullets a 1in12" will serve you better and longer,especially in high volumn shooting.I have a .22-250 custom rifle in heavy barrel and 1in8"twist so I can use 70gr bullets and it heats in a hurry.Especially on days that it is nice to be on the range.For varmints,even high volumn shooting on pd,s I would recomend the 1in12. sam.

Projects are so much fun,and dont forget Timney Trigger on that Mauser. sam.

[lefty o]

1-12, or 1-14" will do what your asking. the 1-12 will be slightly more versatile.

[sbowers5]

Ok sam i have cleaned up the action put it in the lathe and trued it up drilled and taped it for the redfield mount reshaped the trigger guard and floor plate area and polished the whole thing, ordered the timney trigger with a safety and a new bolt shroud, a shelin barrel with a 1 in 12 twist and removed and welded on a new bolt handel and ordered a triple AAA walnut thumb hole stock from richards microfit, so i'm off and running will let know how its going from time to time and thanks again for the information.

Sounds like a good start,wish I had something going. sam.

sam I have a turkish action with no bolt I can send you if you want it it is the large ring with the small ring threads, that should keep you busy for a while, and you can't beat the price it free.

I thank you very much and apreciate your generosity.I have enough to do if I get busy.I dont think you can ship an action except through a licensed dealer.Actions are considered firearms.I really dont know.Mooseman would know.Thanks again. sam.

[sbowers5]

I am a licensed dealer and gunsmith and it is not a complete action but i would still send it to an ffl up where you are if you want it, you would need a bolt, and all its innards, and a bolt stop and floor plate, cartridge follower and spring.Anyway i thought i would offer.
