.223 & .22-250 twists

Sig220_Ruger77
Why do some companies use a 1:14 twist in rifles chambered for the .22-250? The same companies usually use a 1:12 twist in the .223. I don't understand it myself. Basically limits you to using a 60 grain pill tops and with the 1:14 you are extremely lucky it you can even use that heavy of a pill. I understand that these cartridges are mostly used for small varmint(and maybe that is the reasoning), but with a 1:12 in the .22-250 and a 1:9 in the .223 it seems that you are given more options in bullet choice and can definitely stretch you game up to smaller deer, as well as being able to use a heavier grain pill for varmint such as coyote, etc.

    Think of it the other way. With a 22-250 in a 1:14 twist you can go down to those ultra-lightweight bullets running well over 4000fps. That is a dedicated varmint bullet. A quicker twist rate does give you a greater selection when it comes to bullets, but the 14" twist will stabilize the lighter bullets better.

    All depends on what the intended purpose of the rifle is.

    Very valid point. I guess I just wish they would take your last comment into consideration a little more. Savage seems to understand this as I believe that they make the .22-250 in multiple twists(1:12 and 1:10) where as Remington offers a 1:14 only. I guess that this is the point I was trying to make.

    I don't know why Savage offers more than the others. But I'll bet something as simple as economics has something to do with it. I'd imagine the other gun makers decided that, based on their sales, more people were using the 22-250 for varmints than for big game, so they scaled back production. Savage has tooled up for all kinds of variations over the years. They must have an less expensive set-up. As a left-handed shooter, I'm eternally grateful to Savage for their selection.
