More adventures with the Collar Buttons…
I loaded up five loads with 9.0 grains of Unique and another five with 14.5 grains of Unique and went off to the range…
The first four rounds of the 14.5 grain loads went into a single hole at 15 yards. Light recoil and a satisfying report. Round 5 went “click-bang”. That shot printed 1” below the rest.
Round 1 of the 9.0 grain loads went “Click”. The case ejected empty. I looked through the bore and it looked obstructed at first, but then there was a little light showing in the upper right quadrant. I ran the cleaning rod in from the breech and pushed out powder. The bullet had apparently left the barrel. No further rounds of this loading were fired.
I am going to use some nice fresh Winchester primers for the next adventure. I am debating whether to try some Bullseye loads or wait until I can obtain some Trail Boss.
I am beginning to suspect that the light bullet, with lots of lube and minimal bearing surface, is scooting out of the barrel before the pressure can build up for proper burning. With all the burn failures I have had, the bullet seems to have left the barrel under the primer impulse alone. I one case I thought I pushed the bullet out, but never could find it, so the blockage could have been the powder.
If I am blowing the bullet out of the barrel, using a wad would not work any better.
Something is certainly abnormal, since others have used these bullets successfully…. It is possible that I should use these bullets for fishing weights and go to 300 grain bullets for reduced loads.
