Reviving this thread, because it's the only one I can find with any mention of .38 Long Colt.
I shot Walls yesterday with .38 SPCLs in a GP100. I was reloading using moon clips weak handed off a belt for the first time, and Dave N, (the RO running me), went through my split times with me. I'm losing about 5 seconds on each reload, (I can reload strong handed in about 4). Part of that is simply practicing; I've been strong hand reloading since 2012 and just tried this the other day for the first time.
The other part, (and why I'm posting in reloading), is that Dave said that I was losing a lot of time because I'm using .38SPCL rounds. He suggested that I look at .38 Long Colt for that kind of competition. I'd never heard of the round. He said that the case lengths are shorter which will make them drop in (and out) easier, and that I can load them with 9mm rounds which typically have a better profile for feeding, (pointier).
Looking around this morning for any information about this case/round. Looking for brass sources, loading data, even things as basic as do I need another set of dies or can I set up some combination of the .38spcl and 9mm dies that I have?
Thoughts, links, any help would be appreciated.
