Some constriction on turkey choke

You do not know, till you know. I install my own choke tubes in Riot Shotguns and Single barrels, become Turkey guns or long range buckshot guns. Also, some factory loads may pattern better than another factory load. Time and dedication is the answer, plus a little money.
