I can tell you this much the muzzle velocity of the 45 is 802 feet per second
and the BAR 30.6 was 26 to 2800 FPS also the used armore piercing rounds from what I read.
I also own the twin to thier car but I haven't shot at it .....yet
Thanks that helps me a lot, the inside of the trunk is good also the outside, just need the hinge and latches.
I will send for the gasket you mention and once again thanks For Your Reply and help.
