Black Butterfly Ammunition has partnered with North Carolina based Performance Gunworks to make case gauges for the 450 Bushmaster. This gauge helps you check your ammunition to ensure that you do not exceed maximum OAL of 1.70 in the body case length. This also checks important areas in the base, body and neck due to the tapered nature of this case so confirm the body will chamber. It is recommended that even randomly check new brass. This tool will work with both brass and completed ammunition.
FAQS: How do I use this tool?
Take a completed round, drop into a clean gauge, then set a straight edge over the top. If you can see a sliver of daylight between the straight edge or it is flush, then you are good to go as far as case length and body size. Remember to always, measure the COAL to insure you fall below the SAAMI spec of 2.26" with the projectile inserted.
