The NEF 10 gauge is a super gun! I have 2 of them and tested alot of chokes and ammo!!!! The best i found in mine and my buddy's is a Kicks .695 or a Kicks .690. The chokes work great with lead and the Fed HW. In my experience do yourself a favor and get some Fed Hw #7 yes they are expensive but are worth it!!!!! you should be able to turn 213-230 in a 10 inch circle at 40 with the Hw. I know that the .695 works great with #5 and #6 lead, and the .690 works super with the Hw. The best shooting lead shell in this gun was a .695 Kicks with the lead Federals with the flight control wad which are avail pretty much anywhere. I was getting around 145-160 with these and they are much cheaper! I would definitly suggest you send that barrell to William at Sumtoy and have him install the Williams rifle sights on your gun he does it for a great price and is a super guy!! or do what i did and put a red dot on that baby!!!! good luck i hope i helped you, Take care!
