K; I can't see from the pics where the springs "clash", in pic 2 & 3 there seems to be sufficient clearance. I doubt "square" springs where used on a round guide. Perhaps because of the rust etc. you need to insure the pins are riding free of any 'crud resistance' sans springs first. Also check the pins protrude sufficiently in the fired position. Nice cleanup by the way - like to see those old ones revived instead of scrapped. FWIW - John Can.
