Biggest Hollow Point Underwood Maximum Expansion. 45 Colt VS. 40 SW
In a journey to try to find a decent load for the S W Governor, I am testing the Underwood Maximum Expansion 220 gr solid copper hollow point in. 45 Colt. To compare that to something else I am testing the Maximum Expansion 140 gr solid copper hollow point in. 40 S W through my 5 S W M P pistol. I do a 4 layer denim and 10 Clear Ballistics test with and without 1, 4 MDF and a chronograph and practical accuracy test. Always appreciative of any channel help :)
