Hacksaw,

I have made umpteen thousands of shotgun reloads and fired thousands of rifle rounds. The primer of David's was dimpled (quote: "plus mimicked a fired primer in the base." unquote), yours was not. Rounds of that size might be acceptable as models, but smaller calibre rounds could look authentic. Could result in getting a firearms response team on the scene these days.

I've been driving around with mine in my car blush.

BUT, as you correctly noted i deliberately made mine look like a fired primer, plus I only drilled the brass bar just beyond the bullet so the bottom three inches or so is solid, and in addition the bullet is only a loose interference fit, so it can be pulled by hand to prove the dummy case is solid/inert.

My firearms enquiry officer is very picky, I don't want to upset him! wink.

Should I centrepunch it then ? I dont want 5 years mandatory surprise I have another friend who's a QC , he had to send someone down for 5 yrs ,for an airpistol being too powerful .

Five years is indeed the mandatory sentence for many Firearms Act 1968 offences, and it is an absolute offence - possession is possession, with little mitigation.

Nope, centrepunch isn't necessary, yours can be proved to be inert/ a replica. It's a lump of stainless and copper that looks like a cartridge, nothing else.

I only dimpled the base of mine to look like a primer strike because i am a nerd blush.

The other day, I bumped into an Engineer who had made a 105mm WW1 canon replica, with blank shells to match. The original was 110mm, but under French law 110mm and above are now illegal to own (privately) in working order, so he made it 105mm which is OK ! Great place to live over here.

Hi Roger

Flat top to the tool and hone to a fine polish. The finish will only be as good as the finish on the tool so make the effort. Cut dry as has been stated.

If you are drilling stone your drills so that there is no rake or they wil grab. This can be done by rubbing the cutting tip on a stone or small diamond card parallel to the drill axis. You will want to keep a set for brass.

regards Martin

If you've a bench grinder with a fine (- ish) wheel, you can use the side of the wheel to grind a zero-rake platform on the drill lip no more than about 1/2 mm wide. Then you can quickly return the drill to standard if it's too fiddly or expensive to keep a separate set for brass.

I've always worked on about 300 ft/min or 100 m/min for the most usual CZ121 brass, which is free-cutting with a discontinuous chip (bits go everywhere as has been said!). There are tougher brasses like CZ106 which I've always machined a bit more like mild steel - about 100 ft. or 30 m/min, a bit of top rake and sometimes bundling swarf ribbons. All for offhand-ground HSS tools.
