JBJ Custom Guns has done 3 custom Weatherby's for me. Here is my 2000 yard stick Jim did for me. It is a sub MOA rifle out to 1500 when conditions are perfect.
Here is a pic of the business end with my Tubb Break and level.
Here is a group with my 257 Weatherby he did for me at 1200 yards. My log book says the wind that day was from 2' at 6 mph.
