Matt,
Find the nearest Range that holds "Across the Course" ("X-course", i.e. 200-300-600 yds) Highpower events, either CMP's EIC events and-or NRA Highpower. Contact the Match Director and get signed up for the first event on the schedule. Just go and do it. The old hands will help you out and you'll learn more by DOING in one day than you can by reading books all winter long.
If there is no range near you holding "X course" events, find one that does short course Highpower. Lots of CMP local clubs out there doing John C. Garand type events at 100 & 200 yds. By doing the basic skills of marksmanship at short range, you'll be set to graduate to the long course whenever the oportunity arises.
I started shooting CMP and NRA short courses 4 years ago at our local CMP club. Got the basic skillls down in short order. Made NRA "Expert" my second year of competition. My third & fourth years I started traveling to some "X-course" events.
The changes in distance over "X-Course" are nothing more than elevation changes on the rear sight. Any moron can master that in one lesson. The hard part as range increases is being able to read wind.... I'm getting better, but still working on it
I'm "tickling close" to "Master" Class now, and all I shoot "X-Course" with is my Match Grade M1. I probably could have made Master this last year but I'm bound and determined to shoot my first Master class X-Course score with my M1, then I'll proudly hang it on the wall and go over to the AR....which should see me holding my own a bit easier.
Enjoy the challenge..... give Highpower a try and the skills you long for will come to you. Guaranteed.
Best regards,
Swampy
