Rifle twist ?

ChetStafford

I just bought a Savage model 12fvss in 22/250 it has a 1-12" twist about how heavy of a bullet will it stabilize?

csjs1194,

From Shilen's website:

.224 CF
- 7" for bullets heavier than 80gr.
- 8" for bullets up to 80gr.
- 8"* Ratchet rifled 4 groove
- 9" for bullets up to 70gr.
- 12" for bullets up to 63gr.
- 14" for bullets up to 55gr.
- 14"* Ratchet rifled 4 groove
- 15"* for bullets up to 55gr. driven 4,100 pfs or more
- 16:* for bullets up to 55gr. driven 4,300 fps or more

Best.

Nononsense,

Thank you for the help[:D]

I don't know what you are using these bullets for, but I had a 1/12 twist 22-250 that was a one holer at 200 yds with these. A friend borrowed my rifle and his boy killed a nice 9 point in a state where a .22 cal is legal.

I tend to shoot mostly Nosler bullets but I just might try those Sierra's

Nosler makes a dandy little 60gr. partition now that penetrates well & Winchester has long had their 64gr. designed for deer sized game; these both stabilize in the 14 twist and should work well in the 12. Depends mostly on the bullet's length, designers have modified the nose of heavier bullets on the upper edge of the envelope to keep them short enough to stabilize in the slower twists and you might even find a heavier one around 70gr. that works.
