I'm shooting in IDPA and USPSA. I've been shooting 45 ACP in a Redhawk 45colt that was milled for moon clips, but I have so much freebore that my accuracy is not what I need.
So I thought I'd try the same thing with the GP-100, mill it for moon clips and go major. I want to do it with shorter brass for the reloading edge.
I had thought about the reduction in case volume and was thinking that I would probably drop to 6 grns of Titegroup and work from there, up or down. I need 1350 fps with that weight bullet.
It could be that once the speed loaders are out of the picture, that I have more than enough clearance from the grip to drop the clip right in.
The smart thing to do here is get the milling done first and see if length is an issue.

Thank you all for the thoughts and cautions. I appreciate all the responses.

Reards,
Charley.
