My Tip of the Day-armprairie
Oh, It's [U]five[U] grains to the mark!
When using the old beam type scales (like I'll use till my dying day), look, then look again at the marks on your scale. Make sure your cipherin' the way the scale makers intended (sorry to use big words). Make sure everything is sitting squarely in the bottom of the vees. A little grit in the wrong place can raise heck with your day. Be as careful with that little jewel as you would your own eyeball.
Foot controlled case trimmer.
I used a motor and foot pedal from a sewing machine that I bought for $10 at a thrift store to make a powered case trimmer.
