I just shot my new set up, I got a 835 24" with a PG .670 and I picked up a box of 3.5-2-6 xtended range and I have not polished the barrel yet and I did 3 shots to get an average and the first shot was 185 and I did not have anything to run through the barrel between shots but the second and third shots were 181, 183.. I think with the price of the h13 loads I am gonna switch back to the xtended range because these are alot more consistant and even pattern!
