Range Report Part II: Rock Island Armory Rock Ultra MS

I used its second range session to raise the round count, make sure everything was holding together well, and get past what might be considered the break-in period, were such a period required. Thankfully, the Rock Ultra MS handled the 400th cartridge as adeptly as it did the first.
