Ruger 77-22 in 22 Hornet twist rate

Recently purchased a Ruger 77-22 in 22 Hornet and used the cleaning rod to check the twist rate. It come out at very close to 1 in 14 inches.

Do all the 77-22 Hornets have a 1 in 14 twist rate and if not is there a cut off serial number range. Mine is 77-066xx. Thanks

Call Ruger customer Service on Monday and ask them that question.

Yes, both I've had/have, have 1/14" twist barrels.
I've gotten stability up to 55gr flat base bullets.
My favorite load is 12.5gr Hodgdon Lil'Gun under a Sierra 40gr Varminter Hollow Point. Gets 3,000fps from my 24"bbl M77/22Hornet KBZ.
The Carbine I had, had a terrible chamber. Like it was cut by a loose, wore out reamer. Soured me on most Rugers to this day.
