Getting back into the 22-250Rem again after some 30years away from it. In the past I was not that much into learning about it. I just wanted to shoot it. I had a NEF Handi Rifle Varmint,with a heavy bbl and fairly massive stock. While it shot good,post tweaking,it was not a "tack driver",especially with the bullets offered back then.
The chambering was first made back in the late 30's. It was simply a necked down 250-3000Savage. It was initally called the 22Varminter.
In the mid 60's Browning chambered it in their Hi -Power. It was the first,and possibly the ONLY chambering offered in a production gun as a wildcat ( no factory ammo produced,reloaders only). In fact I believe that it is still the ONLY. LATER remington came out with it chambered in their 700 and XB Match.
It has the same case head as a 308Win so the same shell holder can be used when reloading. It is a RIMLESS chambering so it works well in the guns that are mag fed (lever,bolt,and semi- auto). Even in the AR actions.
In the mid 80's both the New Zealand and Australian SAS Regiments used the 22-250 in their Tikka M55 counter sniper/urban warfare guns. Unknown what loading/bullet.
The twist rates for the 22-250 are somewhat varied. All the older guns that I remember were 1:14. Ruger produces their American with a 1:10. Quite a few guns now come with a 1:12 twist.
When using the newer,heavy for caliber .224" bullets (>75grs) a 9 twist would be needed. Even faster using the 90gr. The 10 twist guns would be good for most "normal" heavy's like the 75,77,etc. For "normal" coyote hunting using the 60,62,65,etc,the 1:12 twist guns would be great. Especially whan using the solid copper bullets. The 12 or 14 twist would be ideal for the light and fast choices in bullets/loads.
FAST - - -> Hornady has a factory load pushing a 35gr @ 4450fps. Multiple manufacturers offer loads >4000fps. You can get a 50gr at 3900fps.
Barrel Burners - - -> I feel that with proper bbl prep,proper cleaning,proper allowance for cooling,a 3850fps speed would preserve the longivity of your barrel. So the medium weight/length bullets would be my pick. Maybe a 55,but definately a 60,62,65,even in the slower twist barrels.
Remember when computing a proper twist rate for length,forward velocity is also a factor. The 22-250 is not just a 223/5.56's daddy. It is the granddaddy.
