I recommend making your own if you shoot a lot. I make them with a tool from 22sharpshooter.com and primer powder or roll caps. It’s fun to do and cheap. Lots of videos on how to do them. I use .005 brass over aluminum cans and can reuse them.
They need to be snug right on top of the nipple. As much as this compound is very impact sensitive, it isn't as sensitive as fulminate or other commercial mixes. Getting enough in the cap is just as important as it's fit. Acetone should do the trick to firming up the mix. If the jostling of the caps is loosening the mix, massive a piece of foam in your tin to hold everything still would help.
I just got 1000 RWS #11 for $104.
Just take your time mixing and use all antistatic stuff. I use a shot glass and thin wood dowel to mix. Found a package of antistatic micro spoons on Amazon to measure the mix with.
I have never tried it, but Sodium Silicate (Waterglass) should not only bind the priming compound, but seal it in place giving some protection against moisture. I've read that Sodium Silicate was used in some of the original percussion caps and early cartridge primers as a sealant and binder. Many of the pyro folks still use it in fireworks wherever a glue or sealant is needed. If I purchase one of the cap punches, I plan on using Sodium Silicate just to see how well it works.
It comes with the priming mix. I've bought more with the other chemicals. Must make sure it is a powder form, or get a mortar and pestle of at least 8 ounce capacity and very highly polished(marble is the best), to grind the material. Some glass is in pellet form and is not usable here.
You can buy it in liquid form in quantities as small as 4oz. to gallon jugs. Building centers such as Lowes and Home Depot, as well as Tractor Supply sell it by the gallon or five gallon containers for use in sealing concrete floors. Rutland is one of the brands.
Don't think we're talking the same thing.
Just be sure what you use to seal the caps won't end up being a nightmare to clean up or out later.
Sodium Silicate is Sodium Silicate, AKA "Waterglass". The liquid that Rutland makes is 100% Sodium Silicate, granted, a gallon is more than one needs, but it is also available by Lynn Manufacturing, Inc. in a 4 ounce container for less than $4. Since the liquid form is water based, just use distilled water to thin the solution if needed.
Yep...done just this last spring. 5.00 per tin.
Yep, easiest way to stay in caps. Toby is about as good as they come. Ships fast!
