nice rig you got.i just hope my .50 bmg will fit the table and still let me use the front rest stop.im looking for something steady.i was shooting from the ground .i put some flat stones down but i had to put a 2x6 under my front rest to get on target.i felt like the board was moving around.i was trying to do the adjustment with the main shaft.so i had to put two 2x6's under the rest you could see they were moving around.can you sit behind the gun so you don't heard it when you fire it.i hope so i ordered it today ,is the hard to get it steady.my 240 pounds should help,thanks,keith
