Cliveb Posted January 26, 2020 Share Posted January 26, 2020 I decided I wanted a less cluttered bench and did away with the finished round bin on my super 1050. Replaced it with a funnel/tube gizmo that routes finished rounds onto a bucket on the floor. Today I was somewhat startled (to put it bloody mildly) when a round went BANG in the bucket near my feet. It appears that a round slide down the tube and hit a primer on the sweet spot, cooking off a round. All I found was a couple of fragments of 40S&W brass a few feet away. I think I'll stick with a cluttered bench, or figure out how to slow down the speed of arrival of the rounds in the tub. Helluva load pop in a confined space! Off to change me shorts Link to comment Share on other sites More sharing options...

B_Seehawer Posted January 26, 2020 Share Posted January 26, 2020 Depending on the size of your hose, an S curve would slow things down for you. Link to comment Share on other sites More sharing options...
milanuk Posted January 26, 2020 Share Posted January 26, 2020 I'd be curious to see what the actual arrangement looked like... Sent from my SM-G960U using Tapatalk Link to comment Share on other sites More sharing options...

Sent from my SM-G960U using Tapatalk Pretty straightforward (which in hindsight was probably the problem). A funnel and spring hose leading down at a rather steep angle from the bench to a bucket. Probably a height of about 43 inches. Apparently more than enough to pick up sufficient speed/energy to ignite a primer when struck at the right angle.

Apparently more than enough to pick up sufficient speed/energy to ignite a primer when struck at the right angle. I would think putting a sloping bend in the tube towards the bottom should reduce velocity of the “dropped” round...think of a street elbow like used in electrical conduit where it is curved 90 degrees instead of a sharp 90 used for water or gasses.

Dirtchevy841 Posted January 26, 2020 Share Posted January 26, 2020 I drilled and put 2 hose clamps holding the tube to the side of bucket with about a 90 degree bend at the bottom. Have 2 mounting points in bucket about halfway down and a little further up when the bucket starts filling up. Works great. Feeds into the bucket softly.

shred Posted January 26, 2020 Share Posted January 26, 2020 Hatchers Notebook says back in the day, the rifle primer test was a 4 oz ball dropped onto a firing pin sitting on the primer (whole thing vertical of course). None out of 300 were allowed to fire with a 3" drop, all had to fire with a 15" drop. Probably there's more scientific specs now, but that's pretty easy to relate to.

Cliveb Posted January 26, 2020 Author Share Posted January 26, 2020 Great ideas lonestardiver and dirtychevy. I'll certainly look into implementing them Link to comment Share on other sites More sharing options...
