Good evening Oldbow!
Just checking in before retiring for the evening. Just returned from a gun club meeting and I'll tell you what I did for our shoot last month.
I used a couple of tables my club already have. They are 4ft wide and 5ft long and 34" tall with cutouts in the back corners for right or left handed shooters. The members shoot off them out to 200 yards and have no complaints with them.
The front rest start with a 2x6x32" and a 2x4x32" then stack 2x4x27....2x4x22 .... 2x4x17 .... 2x4x12 .... 2x4x7 and a 2x4x2 for the very top piece. I didn't glue them, just used a couple of deck screws to fasten them together to form the pyramid.
As I understand it, the NMLRA is meeting this month and will set the rules in writing. So far we haven't seen them yet and I just went by the rules posted at the start of this Table Shoot thread.
My club used to shoot .22 X matches at night and we have lots of X targets left over and I used them. They are white, 4" square with a line drawn corner to corner and a 1" circle in the middle with the X lines getting much thinner. They worked well as most all the card is hidden behind the spotter anyway.
Sorry if this is confusing. Robin jump in and help me!
Big John
