Hi Lafeswede,
Appreciate the 'Dacron tuft' mention...
I'll try it.
I plan to begin loading .45 LC maybe by Summer, and in Smokeless, 'Target Loads' especially, yes indeedy, there'd usually be a lot of undesireable space in a Case of that volume, inviting irregularities of Burn ( unless one point the Revolver straight 'up' and tap it a few times, before each shot! or even then...)
