Nick, thanks for the wisdom. Yes I did debur the flash holes since I thought the same as you. The 26gns is max per my manual and also from Hodgon's site. They estimate 49,500 CUP at a seating depth of 2.25. I worked up to that load with no pressures signs. In fact my primers hardly flatenned out at all even with the max load. The spent factory cases I have looked at have much flatter primers. I'm loading them as long as I can and still get them to feed in the magazine which is between 2.25 and 2.26". My barrel is 20" Wilson with a heavy contour. I don't know what their tolerances are but they state it is air gauged. Regardless, I think it should be a shooter and easily capable of sub MOA groups, thus my head scratching.

I have worked up some test loads with some Hodgon Varget and some Black Hills Match brass. I want to give the stick powder a try and see if maybe the ignition was a problem with the ball powder, plus its estimated pressures are lower with a higher velocity than BLC-2. I think the problem may be a combination of the ball powder and Magtech primers. Since I can't immediately eliminate the primer I'm going to eliminate the powder and give it another try. I'll let you know what the results are. If you have any other suggestions feel free to share them.
