I bought a new Jebbs choke this year and tested Longbeards and Mag blend thru my 835 using 3in ers. The Mag blend put just under 300 pellets inside an 8in circle at 30 yards. The longbeards put just over 100. Ive heard a lot of good things about longbeards, but I've tried them in both my guns, using 3 different chokes, and they perform no where near Heavy 13 and the Mag blends.
