Hi people. I am new to the reloading art. I have loaded a few hundred rounds for my xd-9 with a compensated barrel. I use Win. brass, Titegroup powder and CCI-500 primers with a 115 gr FMJ bullet. I am a somewhat poor shot, but my groups were not even good using sandbag support on a bench. I recently purchased 147 gr cast lead bullets with a brinell hardness of 15. I used the same case, primer and powder, but lowered the amount of powder to 2.9 grs. I loaded a few rounds to test fire. The accuracy improved so I loaded up 100 rounds. The cases were ejected about 10 feet with the first 50 - 60 rounds. By the time I had shot the full 100 loads, the cases were only ejecting a couple of feet and one or two were hungup as the slide came forward. When I returned home and field stripped the gun for cleaning, lead had packed at the outside of the barrel toward the chamber end and had not been allowing the slide to fully retract, thus the problem with casing ejection toward the end of the 100 shots. Apparently the molten lead was flowing through the 10 compensation holes in the barrel and was being driven reward by the slide and packed around the barrel. The rifling and inside of the barrel did not seem to be leaded to any extent. Using a brass brush over a dark cloth did not show any signs of lead being removed from the barrel. I am assuming one can not shoot cast lead bullets from a compensated barrel. Does anyone here have experience with loading 147 gr FN lead bullets for 9 mm pistols? Is 15 Brinell too soft for 9mm. Will buying a 9mm barrel that is NOT compensated for my XD-9 solve my problem or do I just need to find the right bullet and load?
