Years ago when the Marines started fooling with the "Special Application Sniper Rifle" or SASR using the Cal. .50 Browning cartridge, I went to CT to interview Col. Brophy at Marlin and discuss his experiences with a rebarreled PTRD in Korea. He still had the rifle, and Maj. Bruce M. Wincentsen had asked if we could borrow Brophy's rifle for test. This was done and in one of the Quantico "O" Club dinner conversations the Cal. .30 Guard Cartridge came up and Col. Brophy indicated that the Bullseye charge was carefully developed at Frankford Arsenal; and tested at Springfield Armory to ensure that an inadvertent double charge would not blow up an '03 Springfield.
While a charge of 16 grains of Bullseye is certainly NOT recommended, and will indeed blow the primer and expand the pocket, a sound cartridge case and rifle will hold, and just be frozen shut! Again, not recommended, but as long as you do as Harris says and use a penlight to make a 100% visual inspection of every case for correct powder fill, and to check for any spilled powder in the loading block, you will be OK. Patience and caution....
