Why not load down a .45LC?
Well, I have a .45ACP loading set up and about 1500 cartridges and a couple of 1911 variants, and nothing at all for .45LC, not even a barrel. If I get a barrel, I'd like it to be for a .45ACP. (I figure it'd be close enough to the Colonial era black powder rifles used on East Coast for white tails to do the job on the local black tails.)
And there's the "detonation" question I've been reading up on recently.
The Kabooms sound like they are from a variety of causes, but one that really caught my eye was a complication of a long setback, bringing to mind the long throats in the .357 barrels.
Seems that with low power loads, the grit from the primers used for those loads was blowing past the bullet and building up in the throat. After several shots, the build up was enough to stop a low power load "in the barrel". Kaboom.
If the experts are having trouble recreating low power "detonations", it might be because they are cleaning the test gun too often, and clearing out the crud that causes the kaboom.
So, anyhow, to thoroughly mangle the subject, I'm going to be wary of low power loads. (Especially in the .357 barrel.)
