I've been working on a subsonic load for a few weeks and getting pretty close to a final load.
So far,I've not found a load that will cycle the action,but that's next on the list.
When we load supersonic we always use the LeGendre crimp with our modified die and have noticed a considerable difference in velocity and accuracy vs uncrimped.
I have been reading not to crimp a subsonic round. That makes no sense to me. I would think the crimp
would be critical to maintain what little velocity a sub round has. Any thoughts? Thanks,Ken
