Snap Cap "Primers"
 

I am looking for a source of snap cap targets, 'primers" or whatever you call that bit of hard plastic.

I have an all-original cased 20 gauge 1930 Brit SXS with a complete cleaning kit and maker's snap caps. The "primer" just fell out of one of the caps and when I emailed the gun maker in London, they quoted me 117 Pounds Sterling (plus shipping) for maker's caps-and they were ebony, not the nickel finish of the originals. I just replaced then with some nice metal ones, but would, as you would imagine, like to use the originals.

I have read that later (top lever) Parkers do not need snap caps, but I would never assume that for this gun, or any other, for that matter.

These caps are well made and the replacement would be very easy if I can just find that bit of hard plastic-a small black cylinder 21/32 " long that drops down in size to protrude and mimic a 20 primer. Behind the plastic is a spring in good condition and a well-machined brass slotted plug. There are some great plastic fabricators here in Silicon Valley, but I can see the look on their face when I bring in this little order.

Any suggestions for finding a replacement would be appreciated. I found nothing for sale after spending way too much time on the internet.

Actually, that applies only to hammerless Parkers. I wouldn't chance dry-firing a Parker hammer gun.

Certainly not elegant, but I have used pencil erasers for the job

An interesting idea, but I can feel the founding gunmaker turning over in his grave...

Your suggestion does bring up an interesting point- if you want to imitate the resistance of a live primer-over many years, what type of plastic should you use? The black plugs on my old caps are very hard, but that may very well be a factor of age and I doubt they had most plastics in 1930.

I'll bet there is a real (read mechanical) engineer out there who can calculate the properties of a live primer. My guess is that the result will be a compromise, starting a bit hard and moving softer over the years. In other words, you should replace snap caps "caps" on guns that need then every few years.

I'll visit a local plastics company next week and see what they can do.

Thanks for your replies,
Patrick

i wonder if the original inserts were horn- horn striker blocks were common.

Suggest you contact Toby Barclay at Heritage Guns in the UK. He makes repro snap caps of his own from old Damascus barrels, and may be able to help you at a more reasonable price. Toby also attends the Vintager events here in the US. His website:

When Parker made the statement that it would do no harm to dry fire hammerless guns, they had been in the hammerless gun business for fewer years, than the number of years they have been gone. I am of the opinion, supported by the photograph below, that, while the occasional dry firing may do no harm, it also will do absolutely no good. In fact repeated dry firing will eventually do harm.
The auto makers may have come out with impact absorbing bumpers on cars 30 years ago, but I wouldn't make a practice of contact-parking.

I don't know how the little plastic do hickeys are retained in the shell, unless they are inserted from the front and ride on a ridge at the back. Any machinist can turn some out of black nylon rod and create whatever bump needed to retain them. Anyone with a lathe can do the same.

Delrin rod. Google it.

now those are just too cool- and my wife just finished Christmas shopping :violin:

so- guess I'll just have to shop for myself :whistle:
