All I will say is...
Many years ago, Remington caps used to be my nemesis. They hated me. They would not fire, or they would not fire off the charge. So I swore off them. Fast forward a couple years... I ran out of caps. All I could get were the Remington 40% hotter. I almost did not buy them, that was how much trouble I had with them. But I wanted to shoot. I bought the new Remington and never had a single problem with them. I would buy them again tomorrow if I needed caps.
The CCI standard caps... I ordered CCI Magnum and the store sent me standard. When I complained it did no good. They told me I ordered the standard even though my receipt showed I ordered the Magnum. Well I was stuck with them. All I had was problems with them setting off my inline rifles with loose powder. I had such problems that even though I had 10 tins of them I bought ten tins of the RWS 1075 caps. The standard caps were for clearing the nipple and for my friend that showed up and had no caps. I finally dumped all of that junk.
RWS 1075 caps... just great caps. They can be a little card to seat on some nipples because I believe they are just a little smaller in diameter then the #11 caps. But if they are on the rifle, the rifle is going off.
CCI Magnum #11 caps... great caps. Never had a problem with them on any of my rifles. They fit all of my rifles. And they 99% of the time will set the rifle off. These are the caps I normally purchase because they work, and because they are easy to get. Although they have doubled in price at my local store this last year, so I will buy a brick of them next time I need some.
