Without a doubt Erik Cortina has done more to enhance the world of competitive shooting in the USA than anyone over the past 60 years in my opinion! Through the world of F-Class shooting Erik has brought through his development of his videos on YouTube an untold number of new shooters. I am an old XTC or NMC shooter having come up through the ranks shooting with USARADCOM rifle team and the AMU at Ft. Benning Ga. and as much as I hated to see that course of fire and participation decrease these past few years, it's a breath of fresh air to see the F-Class shooting world accepted so well! My hats off to Mr Cortina so please keep up your good work sir!
