Seems like the 200 gr XTP doesn’t really like a compressed load of AA#9 above 13.2 grains. I’ve had a good load of 13.5 gr in the past out of my G20 and recall moving the OAL up from 1.260 advertised to 1.280 to help keeping the bullet from deforming the hollow point. The 1.280” plunks fine and still fits in the magazine without hanging up.
Here’s what happens when I seat the 13.5 gr load @1.280”
I’ve added the banner at the start of this thread to meet forum rules since the Hornady 10th edition manual lists 13.2 gr of AA#9 as max (below).
For reference, the Speer manual shows a 200 gr bullet at 14.0 max (Speer #13 manual) but I highly doubt you could get the XTP bullet that high without deforming the bullet more just to test the load that high with the bullet. In the past, I used this manual to work up to 13.5 gr using the XTP but had to stop there because of the bullet deformation shown above.
So there’s no way to know if the 13.5 grain load with the deformed hollow point would expand as expected absent gelatin test (which I don’t have). In the past, this load grouped well in my G20 with KKM barrel with no signs of over pressure. Think I’ll just use up the few remaining XTP’s I have and move to a different 200 gr JHP bullet/powder. Have some Nosler 200 gr JHP inbound and will slowly work up an AA#9 load shortly.
