Ran off about 75 rounds with different powers/loads and bullets based on suggestions from a bunch of people who load is round regularly. . Out of 6, the best groups I attained from a bag rest were with 115g Hornaday JHP over 7.6g bullseye. Clocked in at an average of 1354. Tightest groups but I didn't bother to measure them. I have the dillon dialed in so I plan to run off 200 rounds and spend some time at the range this weekend. Very nice round to shoot, better than expected accuracy from the shorter p239 barrel and recoil/back on target time was completely acceptable. my carry gun is and always be a 45 but my backup is a sig232 which is just a little smaller thank the 239 and if I cut the edges on it, I might be tempted to switch to the 357. No idea of the terminal ballistics are with this load combo at this point so if anyone knows or has a better recipe, I'd love to hear about it. Thanks for the response and the advice on resizing the 40's.
