I have read over most the posts regarding choke tubes for the 930 SPX. Most people post the brand of tube they got but don't mention the type of contraction for the choke. Example - Improved Cylinder, Skeet 2 (Lt. Mod.), Modified, Improved Modified, Full, Extra Full and others.
I'm shooting in 3-Gun and use bird shot, buck and slugs.
I need a choke to improve long-range steel and clay shooting.
If you would be so kind I'm looking for specific choke recommendations of Brand, Type and Constriction.
Thanks in advance.
