Lately I have been using the "Swedish capper" as shown on Mike Beliveau's You Tube channel(Duelist1954). It is made of plastic, roughly star shaped with the caps contained at the end of each "arm" of the star. Each one only holds 6 caps so you would need several, however at about $4.00 apiece I think that's pretty reasonable. The nice thing is they are small, light and so far they easily cap every gun I've tried them on including Remingtons. I don't know about the durability factor yet as I've only been using them for about 6 months, but at this point they have made me want to retire all my other cappers.
