A buddy and I tested this combo in his gun during the involuntary forum hiatus. I thought my chrono was broken. I had to test it with a known load to make sure it was still working right. The ammo was some of my stash from the early 90s. I thought maybe the extra velocity was from bullet setback since much of it had been chambered and carried. I don't think that's the case considering the consistency. I hope to take that same friend's G19 out and test rounds from that box with the shorter barrel and test some of a new box to see the difference.
Known load was my duty load. 40 Cal 155 HST's. I just used that to make sure my Chrony hadn't gone wonky on me and I know what they run out of my M&P (1195 or so).
