Jon,

This ammo was available everywhere as surplus in the '60s and '70s, really cheap. I put most of a case of it through a Nickel 39-2 and a surplus Radom a long time ago.

One little bit of warning- the flasholes are on the tight side and tended to pull decapping pins out easily, which really slowed down an early Dillon.

For reference, check out the RIFLEMAN, 12/63 and 7/69, as well as an interesting article by Lee Jurras of Super Vel fame in the 3/72 SHOOTING TIMES.

The collector thing may be some smart advice today.

Good shooting.
