I tested a few loads this weekend with the Xtreme 9mm 124gr FP bullet and HP-38. So far I like what I see. Following is the best grouping load I tested, but I still need to do some additional loads, especially at the higher end. This load is just a light accurate load, but not making minor PF if that is what you are looking for. Testing was done from a rest with chrono at 12 yards and target at 15 yards.
