twist rate for Model 12

[champ198]

i have a Model 12 22-250 with a 26" bull barrel. do any of you all know the twist rate is on this gun off the top of your head. i bought the gun used and have no clue on what the rate is.

Unless it is marked "1 in 9 " on the barrel it is a 1 in 12.

[champ198]

i assume that it will be marked down by the barrel nut?

[champ198]

the only thing i can see on the barrel other than the normal stuff is stampings that say A2, SP2 or SF2 and E3

Yes, It will be in the roll mark with the model number.

This is one method of measuring twist rate also. Brian Brown.
