I just purchased a Savage Model 112 heavy barrel chambered for 22-250.
• Sn F104849
• Black, synthetic stock
• 26” Barrel length
• 7/8” barrel OD at business end
• Stamped barrel markings: |3| |3|, 63, D, SP-9
• "4849" freehand etched on bolt

Does any of this information help identify the twist rate?

I have tried the cleaning rod/patch method to check the barrel twist and do not come up with the same answer twice.
