Yup, but with loose T7, they work great!!! They're all I use, see no need for the 209s and the problems they create. And if you want to make the musket cap waterproof, just get the flangeless RWS musket caps from www.DNRsports.com or cut the flange off the flanged type, and slip a piece of surgical tubing over the cap and you have a legal, waterproof, Washington state approved ignition system!

Has anyone used 777 pellets with Musket caps? Iknow they say it is designed for use with the 209 primers but we can't use the 209 here in Washington. Just curious if you get a full and consistent burn.
