If you want to shoot off some full-auto weapons go down to the Knob Creek machine gun shoot. I hear it's a blast.
I've shot basically everything under the sun as far as full-auto US/Russian military arms. M249, M240, M2, M134, 12.7mm Russian, PKM, RPK, AK47, MP5, Sweedish K (like a greese gun in 9mm), and a MAC 10. I'd really love to fire an H&K21 and a UMP45.
