For the Bushmaster 450, I was only able to get a 5 shot group because the scope mount came loose and I ran out of ammo before I realized what had happened.

I plan to go back tomorrow to test for more groups on the bench.

**Rifle2: Bushmaster .450, FF Forend, 16" Barrel, Millet 1-4x**

Here is the ammo I will be chrono'ing.
