I currently own a Huglu 202B 12 gauge and would like to convert it to a 500 NE 3". Now that Hornady is making brass and bullets this round is very affordable. I have read Ron Vella's take on the monoblock construction of the Hulgu/CZ SxS. Can a 500 NE be built on this gun and use the existing monoblock to construct the gun? Also, does anyone know someone that can do this work? Thanks!
