They are for a Ruger red label o/u 12 gauge. They are extended and one is marked 745 on one side and 5 on the other. The other is marked 745 and 10. No other markings. What constriction are they? Brand? I can email pics if necessary. ----------------------------------------- Roll Tide! Glock Certified Armorer NRA Certified Firearms Instructor | ||

If you search Google with “measuring shotgun choke,” you will find many discussions. The best way is probably with a chart and calipers, but as stated in one result, strictly speaking chokes are ratios, not necessarily absolute measurements. There are, however, choke measurement tools available as well, like this: https://www.brownells.com/guns...gauge-prod10984.aspx ► 6.4/93.6 ___________ “We are Americans ….

Best I can figure is 5 is .005 which is skeet and 10 is .010 which is IC. Not sure about 745 stamping on both. ----------------------------------------- Roll Tide! Glock Certified Armorer NRA Certified Firearms Instructor | |||

Red Labels are slightly overbored to .745. Standard 12 ga being .729-.730. So you have a .745 bore and the chokes are .005 and .010 which are, as stated above, Skeet 1 and Improved Cylinder. I'm gonna vote for the funniest frog with the loudest croak on the highest log. | |||
