I am starting to reload the 40 and would like any suggestions anyone may have. I already have some titegroup powder and Montana gold180 grain cmj's. It will be mostly for my g35 for idpa and Uspsa. Big question is how much grain titegroup for the 180 grin, start at 4.2 and work up to 4.8 grn? Wanna kill these ads? We can help!
