Mossy, they ain't too hard to find. Go to the gunshack in Mt. Airy. I get 215Match. Bass Pro usually has them. I buy them by 1000. Clydes sports in Brooklyn (b-more) has em usually. You know you had such good luck out of WLRM I was thinking of picking up some of those.

In your Rem Mag, you can get by with Fed 210 Large rifle. Especially if you using powder faster than RL22. The real slow powders like RL25 and Retumbo, need the hot primers. IMO. Here in MD, no needed. I have seen some people using 210's in RUM's with great success in Texas.
