Last year I shot the LB's #6's out of an 870 SM with the .660 JH and got around 180 hits - then from the advice on here I went to a .665 JH and got around 230. Seems like the lead wanted to be opened up a bit... But I personally did not like the LB's in the field near as much as the Hevi-13, so I went back to old faithful Hevi-13 and haven't looked back!
