doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Safety Issue: Defective Snap Caps Slide Down Bore

That's right Jagermeister. You have repeatedly lied to us. Anyone can come up with a picture of a Remington Model 1100 and photo-shop a bill of sale. If I made these two posts only a couple weeks apart, would you believe anything I posted afterward?

This second statement was also shortly after you told us you no longer hunt. Here's a link to more of your B.S., and attempting to explain away one lie with another. What a jerk:

As best I can recall, I used Hoppe's Elite Gun Cleaner and a 20 gauge bore snake prior to inserting the plastic snap caps for winter storage. Although one would not expect a rimless snap cap to slide down the bore, as noted in my post this in fact did happen in both bores. I just checked the internet and regrettably, these plastic snap caps are still being marketed. The pistol version of the Pachmayr snap cap appears to have a brass ring around the base, while the shotgun versions appear to have retained the plastic base and ring.

(It is worth noting that I visited the Lyman website and used the contact information to alert them to my experience with their Pachmayr branded snap cap. I have not received any feedback from Lyman.)

Based on my experience it is indeed foreseeable that there will be serious injuries resulting from this product. If any member has a personal contact at Lyman, suggest you contact the person so that they may take necessary steps to research and correct this condition.

Something related to the snap cap diameter and your bore diameter does not seem right. Maybe your bore has been altered. Does the snap cap slip entirely up the barrel to the choke area ?

Why not measure the snap cap diameter , and then measure the bore diameter ? Most German 20 ga bores are fairly tight. Measure the bores just ahead of the chamber, then at 1" intervals going toward the muzzle. I wonder if the gun has had the forcing cones lengthened .

A brass rod is going to be harder than a shotgun primer....hope you don't break a firing pin.

There is no rim left on the snap cap. Thus, just as the front of the snap cap slides easily into the bore, there is no rim at the rear to stop it and the snap cap continues to slide down the bore. (The entire snap cap is the same diameter after the rim dissolved.) The snap cap in the right barrel slid down and out of sight, the one on the left barrel slid down but fortunately remained in view when I opened the action.

I have passed this information on to the NRA and Outdoor Life magazines, suggesting that they alert members/subscribers as well as any contacts they may have at Lyman. I have also filed a report with photos to the U.S. Consumer Product Safety Commission. It is also worth noting that reviews of this product on Amazon disclose a number of one star reviews.

It is admirable that you would alert us, the NRA, and USCPSC about this potential problem, but I think you may be misunderstanding what Daryl was asking.

The body of the snap cap should be just under chamber diameter, and the chamber diameter is larger than nominal bore diameter. So even if the rim of the snap cap is totally gone, the body of the snap cap shouldn't go past the forcing cone and all the way into the bore... unless the bore is quite a bit larger than nominal bore size for a 20 gauge (.615") or the body of the snap cap is considerably under the normal chamber diameter.

Actually, a snap cap that had a minimum body diameter of .675", or .010" under the normal diameter of the front of a 20 gauge chamber, shouldn't be able to fall all the way into a nominal 16 gauge bore with a diameter of .662". I would expect it to go well into the forcing cones, but it shouldn't be possible to fully chamber a loaded shell behind it. Your Pachmayr snap caps must be very much under chamber size if it is sliding into a 20 gauge bore.

Keith, well said. Snap caps in 20 ga. that I have around here measure about .680" diameter across the body, not the rim. They would not possibly slip down a normal 20 gauge bore of .615" diameter. Something is fishy.

Still waiting for the Sauer 20 ga. bore diameter and the diameter of the snap cap body [not the rim] from GR8BAY. It would be hard to make any sort of a case with any of the agencies the complainant contacted without those simple measurements.

Possibly GR8BAY used the wrong sized snap caps. Maybe he put 28 ga. snap caps into a 20 ga. Sauer.

Just get some new snap-caps...Geo

Appreciate your comments and insight guys. I don't have appropriate tools for getting the accurate measurements some have asked for. However. I placed the 20 gauge snap caps in 3 separate 20 gauge guns and according to my rough measurements, the snap caps slide into the bores, out of sight, with the defective rim beyond where it should be seated as noted below:

JP Sauer double - 1 1/8"
Pre 64 Winchester Model 12 Pump 15/16"
Winchester Model 1300 Pump 1 1/2"

Thus Keith, you are correct; if I had attempted to chamber a shell, the defective snap cap would likely have prevented the shell to be seated in the bore. It remains regrettable however, that this product is still on the market, as the plastic rim does not hold up.

Again, thanks for your comments.

Sounds like you may have used 28 gauge snap caps. No pictures, no measurements of the snap cap or the bores , leave little to go on. Odd, too, that the rims broke off completely over the storage period.
