Converted these guns back to shoot a little more open patterns so my sons can hunt with them. They are actually better off shooting the factory full chokes and lead 5's out of these guns.
Interesting enough the 390 20g/ Pure Gold .570 shoots the best patterns with Remington Hevi Shot 3" 6's. The 391 Urika 2 12g/ Pure Gold .670 has always shot the best patterns with Hevi 13 3/2/6's and 3/2/7's.
Anyone shot Federal TSS through the Pure Gold chokes?
