Another cap making question

[harleysboss]

So I had a chance to pick up 1000 RWS 1075 caps last year during the cap drought. They are older metal tins but were all new/old stock and had the sealed wrapper around the edges. I have sampled several of the tins and all the caps I tried fired without hesitation. I brought a tin of the old caps to the range a few days ago to try with a couple favorite rifles shooting proven loads. The results were very disappointing to say the least. The guns fired without delay but the accuracy was horrible. Patterns! not groups. I figured it was due to the old caps. To test this I brought a fresh tin of RWS 1075plus caps and fired my last three shots. Nothing changed with the loading except the caps. Last three shots almost touching at 75 yards. So now the question. I have the cap making kit and was thinking that I could use the old caps but load just a little of the fresh mixture into them to enhance the performance? What do you think? Dangerous?

Just my 2 cents, I think you would be better off making more of the cap shells. If I am understanding what you are saying, the old compound plus the new would not leave much room for sitting securely on the nipple/cone. Forget about using something like this on a revolver, the unfired ones would fall off for sure after a few shots.

Yes, that’s what I was thinking. Adding fresh compound onto existing. The cap seems almost empty in the current state. Maybe it’ll just be a rainy day project to make up 10 or so and see.

Let us know what your experience is. It will be good information to store away in the back filing cabinet of the mind.
