Jamie Posted December 3, 2014 Report Share Posted December 3, 2014 Hi folks, I've got a Hornady Depth Gauge, with a modified .223 brass case. I wouldn't mind having a go at modifying a case for my .204 Ruger. Granted the modified cases don't cost a lot, but it's more a case of achieving something than just throwing a few quid at it.... I'm hoping as the .223 Is similar to the .204 they should need similar adjustments? However, I'm finding it difficult establishing some dimensions. Although for what it's worth, I've established a push bike hand pump adapter valve, (The car variety) fits the male gauge threads a treat! Joke and apart, to be exact, I need to know the thread size and pitch of the tap I need to modify the case internally, and what drill bit I need to use before tapping. Any constructive advice would be appreciated. Cheers Jamie Link to comment Share on other sites More sharing options...
L B Jefferies Posted December 3, 2014 Report Share Posted December 3, 2014 Possibly a 5/16x36 thread. When I was planning to make one, I couldn't find a tap for that size listed on the site I normally use. Link to comment Share on other sites More sharing options...

MrCetrizine Posted December 3, 2014 Report Share Posted December 3, 2014 I bought a tap off eBay for a few quid but couldn't work out a way to grip the case without a lathe. Mark (1967spud.com) did it for me for free as he's an awesome bloke. It was this one... http://www.ebay.co.uk/itm/5-16-36-UNF-HSS-Plug-Right-Hand-Tap-5-16-36-/250872007101?hash=item3a692309bd Link to comment Share on other sites More sharing options...
Chris-NZ Posted December 3, 2014 Report Share Posted December 3, 2014 Yeh, the cases can be a bit of a bee-atch to grip. Best to use a case fired in your own chamber. Link to comment Share on other sites More sharing options...

white van man Posted December 4, 2014 Report Share Posted December 4, 2014 I use a base plate drilled and tapped to accept a chuck from a battery drill, put the case in the (upside down) chuck. And drill with a pillar drill. I drill the case then put the tap in the pillar drill and turn by hand. Yep I know it's a case of a sledge hammer to crack a walnut, they are only about a fiver to buy or Spud will do them for free. But it's satisfying,and I'm also using cases fired in their chambers.
