This weekend I took to the range two recent acquistions. One was a well worn 586 in 357 and the other a 95% Colt Trooper Mk III in 357 Mag.
The weather was cold there were infact snow flakes in the air, it was overcast and the wind was blowing. The ammunition had been overnight in the bed of the truck.
I had misfires, no hangfires, and I had squibs with a load I tested in 103 F weather. I had rounds that were anywhere between full power and squib. My load was with a 158 LRN with 12.0 grains AA#9. I used WSP primers. Below is my test data, 12.0 grains AA#9 was close to my “reference” load of 13.5 grs 2400, so that’s what I used.
AA#9 is a very fine ball powder. It shot just fine in warm weather.
One round left a bullet in the throat of the 586, another round left a bullet lodged between the cylinder of the Colt and the throat.
Luckily I had a long shafted screwdriver and was able to knock the lead bullets out and continue shooting.
The bullet stuck in the 586 throat had a column of ball powder behind it. Ball powder was all over the mechanism, I had to get a paper towel and wipe it out from under the extractor star, cylinder recess.
Below is the case that was fired in the Colt. As you can see the bullet was shoved back in the case.
I may have had light primer strikes with the 586, but as you can see from the primer on the Colt case, I had deep primer indentations. I have looked at the fring pin protrusion with the 586, and that looks to be good. It really sticks out.
So, heck if I know. It could be that ball powders are hard to ignite, or it could be sloppy practices on my part. I loaded this ammunition on a Dillion 550B over a couple of years ago. Out of 100 rounds, these were the only two that stuck in the barrel, but I did have squib rounds.
Shot well, even out to 50 yards. The squib loads barely rocked the gong.
