Moose,i got my 10 Gauge SB-2 back in january,mine came with the factory extra full tube,but my mossberg 835 with its after market choke tube and using 3 1/2" shells out performed the 10ga. alot!!!much better pattern at 40 yrds.i got a kicks .690 for my 10 gauge but havent got to try it yet,i need to before gobbler season opens.i like my nef alot,about the same recoil as the 835 and seems to point great and feels good also.
