I've been using TiteGroup for over a year. Works great. My concern is it doesn't take up much space in a 45 acp case. I load in 100 round batches, so I charge 100 cases, weighing every 5th charge, inspect them all, then set projectiles, then seat & crimp. I just witnessed what a double charge of TiteGroup will do to another reloader's 1911. So I'm thinking a bulkier powder will make double charges easier to spot.
I was using Unique good results, pretty dirty though. Switched to TiteGroup for 9 & 45 as it was cleaner, cheaper and more available. There are dozens of published loads for 45's using various powders. Don't really want to buy them all to find one that burns clean and takes up more space. Any powder suggestions, other than the obvious- be more careful during the loading process?
