Toying with the idea of building a 22 cal rifle for some of the heavy 22 cal bullets. Have the 70 gr bullets from Barnes and the GMX from Hornady in mind.Would like to keep brass as simple as possible so I am considering a 22-250 Ackley or a 22-243 with a fast twist. A 1in 9in or 1 in 10 inch. Would appreciate any input you might have.

I have a 22.250 with a 10" twist that will shoot the 70 grain lead bullets but it will not stabilize the 75 grain A-Max bullets.

The 70 grain lead free bullets are much longer, I don't think that they will work in anything more than an 8" twist barrel.

Well before I left TX the 224TTH was the rage. Guy on my old lease built one. He LOVES it. He went with a 1in 8. Said he has not tried anything less than a 52gr but had no issues with poor accuracy or over rotation.

ER Shaw called it the #6 favorite wildcat.

No. 6: .224 TTH
E.R. Shaw’s Murray lists the .224 TTH on his top six list. “TTH” stands for Texas Trophy Hunter, and it is used primarily by whitetail hunters, in Texas and similar areas, where steady shots are made from stands.

.224 TTH

Bullet diameter: .224 in.
Max case length: 2.233 in.
Max overall length: N/A
Case capacity: 55 grains water
Typical max-load velocities
55 grain 3,800 fps
60 grain 3,800 fps
79 grain 3,500 fps
75 grain 3,800 fps


The cartridge was created by writer Ralph Lermayer in 1998. It is the 6mm Remington necked down to .224. The rifles have fast-twist (1:8 or 1:9) barrels and use bullets that are heavy for caliber. Velocities can exceed 3,500 fps, and the choice of bullets becomes critical. The advent of good hunting bullets created specifically for this type of application, such as Nosler’s .224-caliber 60-grain Partition, make this a good deer cartridge in areas where it is legal.

Check with the bullet manufacturers-1:8 may be okay or you might need 1:7 or 1:6.5 with the heavy lead-free bullets.

i built a 22/250ai some time ago to shoot the 80 gr sierras with an 8" twist. it does so very well

The 22-250 I kept as one of my personal rifles is one I built with an 8 twist Bartlein. 77gr Bergers make nice tight groups.
