Ruff,
Once fired 44 Mag or 44 Spl. brass ("use" to be available cheap).
Trimming to 44 R length was all that was needed. (that wasn't all that expensive either).
New dies from Lee were also inexpensive, used dies were at one time less expensive than new. You might find cutting down the length of the bullet seating/crimping die would help preform this job if your dies were set up for 44 Mag.
Recoil with BP loads is manageable, with bullets weighing 230 grs or less, provides hard hitting/knock down power, and is quite accurate.
I could load a box of 50 for about $5.00, where a new made box of 50 rounds was costing about $20.00. It didn't take me long to pay for the initial expenses for setting up.
It is, in my opinion perhaps the best CAS/WAS hand gun round available.
My best,
Blair
