.577 Snider Case Trimmer

[The Goose]

I will confess that I stole this from a guy on Youtube (NorthernInventor I think). At any rate it gave me an opportunity to practice on my new Sherline lathe. Some turning and facing work. Took a rod of tool steel and turned it down to fit loosely inside of 24 gauge shotshell brass. I turned the other side down to 1/4" to serve as a pilot for a 3/4" counterbore. When I chuck the counterbore and pilot into the lathe I just push the already shortened case onto the pilot until it stops. Perfect case length every time. Works like a charm. I feel quite accomplished.

A bit like an ID version of the Little Crow trimmers that locate on a shoulder rather than the base of the cartridge. Guess this would work on other straight wall cartridges too. Nice work!

 

[The Goose]

Yeah, would probably work on other straight wall cases, but would have to be made for each case. The problem that I always had with the .577 Snider is that to my knowledge nobody makes a case trimmer. It is hard to cut the case to exact length with almost any method that I use. This way if I get close I can finish it in the trimmer which is what I do with most other smaller diameter cases that I form to other calibers.

Nice idea. Necessity is the mother of invention. When are you going to be making them for sale?

 

[Steve Marshall]

Because someone has to be that *******, I'd chamfer the crap out of the the end that fits inside the case.

Where did you get the 3/4 counterbore? What did it run you?

 

[Rob Boudrie]

That looks like exactly the tool I need to drive a stuck sheet pin out of my snowblower.
