This is about what most of the other groups averaged:

Thanks for the replies, guys. Honestly, I'm really not trying to find a load that's 125.1 PF and shoots sub 1" at 25 yards. I just want to find something 130-135 PF that shoots 2-3" at 25 yards so I can start cranking them out. I enjoy shooting and practicing much more than reloading, or tinkering trying to find the "perfect" load. I have no doubt the problem is me, but I think the problem is at the press, not at the range. For example, the one good 10-shot group I got (out of 18) happened to be the 7th that I shot. I won't completely rule it out, but find it unlikely that I shot six bad groups, shot a great one, then shot another 11 bad ones. I'm just confused by the inconsistency I'm seeing, especially since all those test loads were loaded in the same session. I will also add that all have fed and cycled without issue. Even the longer ones that didn't freely plunk, but again, it only took very slight finger pressure with the barrel out of the gun to get them to fully chamber the last little bit. The more I think about it, I have a feeling it's crimp related. I didn't think I was over-crimping, since I tried to only crimp enough to get the rounds to case gauge, but I'll double check it. I'll shorten them up so they plunk, pay attention to the crimp, and load up a few more test rounds to see what happens. I'll also try to remember to take some 124 gr HST I have to use as another factory loaded control group, and if I have time, I'll shoot some groups with my G19 and M&P9. Will report back. Good group out of the 18:

Hey everyone, I’m hoping someone can offer some help. I’ve been trying to develop a minor load for my G34 using VV N320. So far I’ve tried BBI 135s and 147s, and Xtreme 147 HPs. I’m using mixed brass and Winchester SPP. So far I have only been testing for accuracy, and haven’t chrono’d any of the loads. For some reason, I haven’t gotten very consistent results. The first time out at the range, I tested the Xtreme 147s and BBI 135s using N320. For the Xtremes, I also loaded one batch using CFE Pistol. I shot 5 shot groups, rested on a bag, at about 20 yards. I first shot a control group using factory new Freedom Munitions 147 gr RN. The group measured 2.23”. Here are the results for my reloads: Xtreme 147 HP, 3.4 gr N320, 1.135” - 2.39” group Xtreme 147 HP, 3.9 gr CFE, 1.135” - 2.46” group BBI 135, 3.6 gr N320, 1.130” - 1.79” group (the 5th shot wasn’t on the paper, so I think this was a fluke with the 4 shots being 1.79”) The next time out at the range I tested BBI 147s, using 3.4 gr N320, at OALs 1.120-1.160” at 0.010” increments. Same shooting setup, except this time I decided on 10 shot groups to hopefully get more conclusive results. The best group I managed was about 4” at 1.140” OAL, but the rest were in the 6-7” range. In addition to shooting groups I’ve shot all the loads for feel. I decided that I preferred the feel of the BBI 135s so I decided to focus on those. This time I loaded 10 rounds each at 3 different powder charges (3.5, 3.6, and 3.7 gr N320) and 6 OALs (1.110-1.160” in 0.010” increments). 3.5 gr - Best group was 2.14” at 1.160” OAL. Not bad at all! However, all other OALs were over 4” groups. 3.6 gr - All groups were 4” or more. 3.7 gr - All groups were 4” or more. At 1.110” OAL, the groups were horrible! Only 4 shots made it on the paper. I've shot good groups with the Xtremes, so I was starting to think my gun just didn’t like BBIs until today when I shot that one good group. I guess I could just switch over to the Xtreme 135s, but I’d like to get these BBIs to work. Maybe I can confirm the 3.5 gr at 1.160” makes PF, and just go with it?? However, I noticed another slight problem with this load. It will not pass the plunk test in my barrel. It takes slight pressure to chamber the last 0.020-0.030” and some force/wiggling to get it back out. OALs shorter than about 1.130” plunk just fine. Anyone have any ideas what could be going on?? I tried attaching pictures of the groups but the "Insert image from URL" isn't working. Thanks!
