Welcome to the RPM XL What's New Page!


New 20 Max caliber based on 357 Max case.


We have Hornady dies in stock for $156.00. Cases form nicely by using a 222 FL die first and then into 20 Max. Cases must be annealed.
Have run the velocity to over 3600 ft/sec!


Working on another 20 caliber. 225 Win necked down to 20 caliber. Should be a cinch. Expecting both reamer & dies before long.
We expect the velocity to be at least 4000 ft/sec.


20 Rocket on a 225 Win Case. Easy to form one pass through dies. No neck turning.
We have them on the shelf. $156.00
Velocity as high as 4291 ft/sec with 26 Gr. Barnes.
