supersonic load
I have a Model 1 Sales upper also. I have been working with W296 (which very similar to H110) and remington 125 PSP, and have had a similar experience. 19.0 g behind the 125 remingtons showed high pressure, and with 19.5 gr, it will blow primers out of the cases!!!. I am using Federal small rifle primers. 18.5 grains works well, seems to be a safe load in my gun, and is just breaking 2200 fps.
There are so many variables, don't get too hung up on published ballistics/loads. I think you should be able to get 2200 + FPS out of your gun, and I really don't believe that that 100 fps is going to make a lot of difference in the field.
You can try switching primers, but reduce the loads first, and work back up to it, as it could actually increase the pressure.
I have not tried any other powders for supersonics yet, but do have some AA 1680 in my cabinet, and may try some loads with that powder. I'll let you know.
