The 6UM

That thing is shooting laser beams! I'm curious why or how the 6UM came about? Everything I have ever read or listened to from Unknown Munitions is that they like big cartridges. It seems like over the last few years he is always going bigger!

People can grow:)

Form and I talked about building one off of a 26 Nosler but figured out fast the brass sucks. So Jake and I did some figuring and decided on the 6.5 SAUM ADG brass. We wanted to hit 3400 FPS with a 115 grain bullet and a 20” barrel.
