MOM~ They .408 case is a wonderful platform for a wildcat type cartridge. There are many custom rifle builders on this forum that can build such a rifle. Feel free to contact me if you would like more information on my build. 717.805.0940 EST.

Some of the shooters had a difficult time getting all 5 shots on paper due to the unpleasant conditions we had.
My son also asked me why I didn't hit the center of the target
My last sighter shot was in close proximity to the center of the 17" sighter gong. From there, I made a small correction, then went on the record target. Between the time it took me to make that correction, and shoot the first record shot, the conditions changed slightly, which shifted my group to the left of center. Fortunately, the condition was somwhat constant for all five shots.
