Forming the 17 Javelina **Pics**


Registered Users do not see the above ad.






As you can see above there are 5 main steps in forming the Javalina case.

This is how I form it using 223 LC09' brass and the following dies:

1. 221FB FL die w/o stem

2. 17 Mach 4 Form die #1

3. 17 Fireball Body die

4. 17 Fireball FL die w/o stem



The following steps are the forming process that I follow for forming:

1. Trim to 1.672"

2. Run through 221 FB

3. Run through 17M4 Form #1

4. Run thorugh 17FB Body die

5. Run through 17FB FL die

6. Expand w/ KM Expander

7. Trim to 1.535"

8. Turn necks to .198"

9. Anneal cases and clean







This is a labor instensive case but worth it IMO. Do the math, 9x100 = 900 repetitions, not to mention the clean up. Make sure the headspace is proper as well because with this many steps it just takes one turn to many to off set it.

So, this starts out life as a 223 Remington case and is then trimmed and reformed to make something between the 17 Mach IV and 17 Remington? Looks pretty cool.

Cost-effective...

I really like that you do not have to fireform. Saves money in components, gas to the range and costs associated with putting a new barrel on it because of the dreaded throat erosion. Well done, sir!
