I have mentioned this before,at Whittington/Raton lastyear, I shot well with a rather well used Lefever "H". During the adult beverage period, we were talking guns, what else. Mr. Joe Wood hauled out his guages and started measuring chokes, mine were cyl/ic...Coulda fooled me. But then again Unless someone else has checked them, I dont know and mostly dont care what my guns are choked. Just shoot em......That "H" sure knocks down the roosters.......1 oz #5's
