Trulock Choke Tube EXTENDED BLACK OXIDE FINISH BERETTA/BENELLI 12 GA LONG BEARDÖ TURKEY TURKEY LB5BER12660 Winchester Long Beard™ XR™ turkey chokes These shells use lead shot that are encased in a special solid buffer that fractures upon firing. I don’t have a clue what the buffer is but I can tell you that patterns fired using this type of shell are amazing. We developed a line of turkey chokes for this shell that is shot size specific. We make chokes specific to the #4, #5 and #6 shot sizes. Combine the Longbeard XR™ turkey load with Trulock’s new LongBeard XR choke tubes to maximize the shell’s performance. With this remarkable combo, you can expect 10% greater penetration over standard lead loads beyond 50 yards and twice the number of pellets in a 10" circle out to 60 yds.
