Extreme Long Range Precision Shooting

***For COURSE DETAILS please click on picture below.

1-Mile is just the beginning!  Success in Extreme Long Range (ELR) shooting demands an inexplicable management of your meteorological / environmental instrumentation.  This is a key priority if you wish to get effective 1st-shot firing solutions using your existing / preferred ballistic equipment computation devices.  In this tier-1 course of instruction, custom tailored for super-magnums in ELR rifle configurations, we will teach you how to perfect the symphony of data management systems in a way that still works in real life field environments.  We will show you how “process prioritization” related to ELR shooting will get you on target out to the maximum effective range of your rifle.  This is NOT a course for the novice who wants to hastily send rounds downrange until he finally hits the target…  in this course, Rex will expound upon the dynamics and priorities that professional ELR shooters must master in order to be effective at distances out to 3,000 yards.   Don’t get sloppy launching rounds downrange in vain hoping that a miracle will eventually happen, train with Rex Defense LLC.  This is our passion and Rex will get you squared away with any concepts you wish to master related to this niche craft.  Ask the experts in the field, Rex Defense LLC is equipped to deliver the proprietary knowledge in a way never done before. See you on the range.

RX3000 ELR - Alumni Reviews


“I’d like to thank Rex and crew, as well as, Joe and the crew of HDMR for one of the greatest weekends I’ve ever had!!!   The rugged Texas landscape was a perfect backdrop for the ELR class.  The gift Rex has of being able to put out so much information in an understandable and digestible manner is inspiring.  Rex’s instruction made hitting out to 2500yds attainable and repeatable.  HDMR’s accommodations were amazing. Joe and crew welcome everyone in as part of the family.  If anyone is on the fence about attending any of Rex’s classes, just go for it, the people you will meet and the instruction you will get are unforgettable!”
