3DNWV:
I use to own a JC Higgins Model 51, and I could shoot 1/3" groups with RL-19 along with a Hornady 180 gr. Innerlock bullet. I sent it to get the stock and metal restored, and one of UPS's employees stole the rifle which was left to me by my dad.
I have some information on my other computer I will try to get to you. The model 50 was totally made and assembled in Belgum at FN. The rifle should shoot very very
well. Good luck.
