I have been handloading for quite a while, but only recently have I been really pushing my loads to the max. In the past, I'd open the load manual, begin with the starting charge, and stop at the first accurate load that I found. Now, I'm working up as far as I can go until I start seeing high pressure signs. My question is this; If I'm working up a load, and start seeing pressure before I reach some pre-determined velocity, And I replace a buffer( gas gun) to eliminate ejector swipes, is this not creating a potentially dangerous situation? The presence of ejector swipe is letting me know that high pressure exists, so by eliminating the swipe, high pressure still exists, but now I may try to go even farther, without knowing the absolute max till it's too late. I want all the velocity I can get, just don't want to destroy a weapon or my face.
