I loaded up 12 cartridges of .327 Fed Mag using Fed .327 cases, Hornady 100gr XTP, Fed 205M primers, and 5.0gr of Titegroup (max is 5.2gr according to Hodgdon). I went out to chrono the loads. First shot, I got a reading just over 1400fps. This didn't seem right but I figured I was just too close to the chrono (I've seen weird results from being too close before). I backed up to my usual 12' and took 2 more shots, 1233fps and 1234fps. Then I opened the cylinder to look. The first case was a bit hard to get out. The primer on that first case was quite flat, and the case was obviously expanded to max just above the case web. The other cases looked fine, and dropped back into the cylinder easily, but the first case will not go in without pushing hard. So, I'm now thinking it really was 1400fps. I've used Titegroup many times before but never have seen such pressure excursions. All I can figure out is my scale is sticky and I got more than 5.0 grains in that case. But when I weigh, I always get the pan swinging a bit just so the pivot won't stick so that seems unlikely too. I know about powder position sensitivity but usually Titegroup is very insensitive to that. The primer is the only thing different from Hodgdon's recipe. I have had no luck getting my hands on Federal 200 primers. The 205M should be a reasonable substitute I would think. Anyway the other two shots were fine. One other thing, there was actually a day between my first shot and the other two, not that that should mean anything. Any ideas?
