I'm looking at getting a new choke for a project gun i'm working on, H&R 12ga 3"chamber single shot topper deluxe w/ invector threading. any info on performance on the IC .660 or .670 choke? what would be the ups and downs on these constrictions for this gun? thank you, John
The 660 IC shot very well out of my Win 1300 invector. It would be a great place to start. Check out my recent post for the pattern pic.
10-4, thanks for the info.
