I screwed a 5 gallon bucket into the concrete mixer, so now I just slide my 5 gallon bucket into the one screwed in. I also used 1x2s screwed in with gasketed screws in the bucket that holds the brass. The lid on the brass bucket is a gamma lid, screws on with O rings. It's still loud, but it's in the garage.

I loaded 20 rounds of ladder tests in 5 round groups for the .308. 42.0-44.0 grains of IMR4064 in .5 increments in LC11 brass topped with 168 grain Nosler CCs. The first group out of the new barrel was 5 shot at 100 yards .93". Im hoping to shrink it a little more.
