Excellent load cayugad.

The orange are the older actually disc's. They pretty well just drop in and sit there. I don't believe they waterproof your loads. In other words, if you dunked the whole gun in a bath, water could get pass the disc and into your powder. But like when does that happen anyway? But I guess thats the big commercial knight has. The red are basically not a disc but slides over a nipple on the breech plug to water proof your rifle.

A 209 expands them. And that will change your ignition I believe. I won't use them more than once. They are just too cheap to worry about it. The first time you fit a primer in them is tough. The second time they slide right in.
