Range Report!!!!
new 26" m3000 with +6 (10+1). I polished the tube with increasing steel wool, and some gun oil. Then cleaned all packing lube, and reoiled. Little graphite in the tube. Tested all versions of shells I had from 2 3/4 bulk federal and winchester 7/8 oz to 1 1/8 oz (walmart stuff) 1150fps on up. Also esate 1200fps and 1300. winchester AA, and wichester supertarget all 1300+fps. Did a breakin of 100 rounds, mixed of 3" 1550fps and 1675fps winchesters, and also s&b high brass 00 buck.
All fuctioned perfect on full tube, cycled no issues. I think I've got a winner it is fuctioning far above how my JaM Pro 930 did on its first outing(and every one after that).
Thanks all for the input and info! And tip on a Great Gun!!
