First off, I want to thank everyone that always post rep[lies. When I need help this is the forum I come to. Now my problem. I bought a new choke for my son's 20 gauge shotgun and patterned some buckshot. I triedthe big three brands and all shot a foot high at around 35 yards. Should I send thechoke back and try another or could the problem be in the barrel? In case it matters,the choke was a extended extra full Trulock. The WinchestersandRemingtons were #3 buckshot and the Federals were #2 buckshot. Not alot of choices in 20 gauge buckshot.
