Following your gents advice I did some looking around on line. I found a place called America's gun Store and they had some Ultramax 38 Special cowboy loads that were pretty much the same bullet weight and FPS as the 38 long colt and less cost. The 38 LC was listed as 650 FPS and the 38 Special is listed as 700 FPS. The 38 special is a basic Round Nose Lead bullet and should work out great for my NCOWS shoots.
Thanks for all the advice.
If this round works out like I hope it will then I am sure I'll be buying more of it. The 38 LC was going for $289.00 a case (10 boxes @ 50 rounds per box = 500 rounds).
The Ultramax 38 Special I bought was $139.00 a case (same total as the 38 colt above 500 rounds).
The specs of the round should not be too powerful for my ASM 1851 conversion. if I find they don't work out I have an old 38 special revolver I can use them in. So I've got a plan B.
I really don't doubt they will fit my ASM and do a great job. Now they have been ordered and are on their way. I might not have them in time for our first shoot (this Sunday) but I will have them in time for our next one. And I can't wait to show off my pistol and hear it go bang.
Now I think I'll buy a cartridge pouch for my belt to hold them in while my .45 loops are kept filled with my Schofield ammo. I figure that way I can have my cake and shoot it too.
