No, A 22 hornet was designed for and is loaded with very light weight bullets with very short ogives which equates to very short bullets. A faster twist rate is not needed for these short bullets. A 1 in 16 twist is fast enough to stabilize up to 50-ish grain bullet at hornet velocities, which is heavier than it was ever designed to shoot.

As for the others. You have to keep in mind that you are talking about production guns made for Joe Average. The 221 and 222 are nothing but varmint rifles (despite their competition origins) from a production stand point. The twist rates that they use are plenty fast enough to stabilize and and all typical 22 caliber varmint weight bullets.



Obviously none of this would apply to reloading and custom barrels and chambers.

Bulls,

That's what I thought..................?!

I know there was more to learn in there, but that was the gist of it.


Thanks

many people will dissagree with you on this.

A more significant issue concerning the Hornet is the question of optimum rifling twist rate, which has definite impact on accuracy performance with different weight bullets and different barrel lengths. The SAAMI-spec standard twist rate for the .22 Hornet is 1:16 inches, which dates from Whelen?s original work. This works fine in rifle-length barrels with the Hornet?s standard 45-grain (or lighter) bullets but not so well with other popular .224-caliber bullets weighing 50 grains and up (especially the long-nosed ones).

It's too slow and doesn't stabilize the bullets. Accordingly, several modern .22 Hornet riflemakers adopted 1:14-inch twists (Kimber's Model 82 and Ruger?s current Model 77/22 are two examples). European rifles like the Sako Model 78 remain 1:16. (My somewhat idiosyncratic fellow ST staffer Layne Simpson has long threatened to have a custom .22 Hornet benchrest rifle built with a 1:10-inch twist just to prove that it?s really capable of superb accuracy with match-grade bullets.)

A faster twist is also preferred for hand-gun-length barrels, even with standard 45-grain and lighter bullets, due to the inherent velocity disadvantage and shorter engagement time. T/C Contender been bored at 10- and 14-inch pistol barrels have always been bored at 1:14 inches. The new MRI BFR single-action revolver is specced with a very fast 1:9-inch twist rate (the benefit shows in the shooting chart). By contrast, the Anschutz Exemplar remained with the European preference for the SAAMI-standard 1:16, which is also the twist rate or the German-made barrel on the new Taurus Model 22H.

That pretty much repeated what I stated in my post.

The 22 hornet was never designed to shoot heavy, long sleek bullets. People that are loading longer, heavier, and sleeker bullets are asking it to do something for which it was never designed. These people will obviously need to rebarrel with a faster twist barrel in order to shoot these bullets.

Bullet weight has absolutely nothing to do with determining the proper twist rate for a bullet. Bullet length is what matters. Look at a hornets bullet profile and look at the profile of a bullet designed for the .223 or 22-250.

Now, the hand gun dilemma I fully agree with due to the velocity loss in a 10" - 14" barrel vs. a rifle barrel.






You may be surprised to know that a .22 long rifle barrel twist rate is also 1 in 16".

I aint buying that, 222 push a 40 gr to 3500 fps with no problems in a 1-12
a hornet is only gonna get 3 k and 2900 out of a 40 and 45 gr.
My NEF hornet is a 1-9 twist and it shoots 50 gr 45 gr and 40 gr hanloads, and 45 gr factory loads with the same POI out of all of them. She'll put 50 rounds in a 2" circle at a 100 using any one of these ammo

thats why the hornet didnt do to well, the 1-16 was to slow for even 45 gr bullets
like the 6mm didnt do well with a 1-12
they do get it wrong sometimes you know.
