So I solved the dilemma of the non-scrunching .38 loads when trying to use a roll crimp. I could not get my .38 dies to seat the capsule before trying to crimp it so the capsule was hanging out of the case too far.
I first ran the cases thru a .38 resizing die and re-primed them.
Then I took the decapping/depriming pin out of my .300BLK sizing die and set the depth to where a .38 case would be crimped by the resizing area where the shoulder of a .300BLK case is.
I found that a 5/16" bolt fits the bore of it perfectly.
I figured out how much bolt length I needed to push the gel capsule to the depth I wanted it using flat washers to set the depth.
Then I just held the bolt down with a 4lb chunk of iron while I seated the capsules. This was for testing only. All I need to do moving forward is to either buy another decapping pin and cut it down as the capsule seater or cut down a bolt to go inside the .300BLK die. The only problem is retention of the bolt so it doesn't fall out the bottom of the die.
These have a full top 1/2 of a capsule full of rice or shot (directly on the powder charge with no wad) under a fully filled capsule on top of it. I overfilled these to where they would barely fit together so I could make sure they would crunch down.
