Thanks Jim for the reply I did try a couple times to smack straight down the screw but so far did not move may try to custom make a screw driver for the screw. the trap and the screw let soak in oil for 4 days an using a exacto knife to work around the edges on the 5 th or so popped open an got of the but plate all the rest of the hardware except that screw.

I was also thinking of reloading for this krag using a jacked or cast round nose about 110 gr bullet an poss 10 to 11 gr of unique powder. I reload also for a trap door that works well using unique powder and cotton or tissue backing up the powder again works well. again thanks for your advice Bill
