I have not attended Darrell's school but I did attend another school at the age of 54. I shot all my life and like many thought I was a good shot and I had made many excellent/lucky shots. When I got into long range , 1 1/2 inch groups didn't make the grade. I thought I needed better guns,scopes, loads, or anything except more skill as a shooter. Long story short, I took a three day class and my groups with same guns, amo ,ect shrank to 1/2 inch. I would highly reccomend anyone getting into long range take a shooting school from Darrell or anyone else who covers all the basics like he does and you will dramaticly improve your skills and confidence. Even if you have shot for years, the class will teach you the correct terminoligies so you can make sence of the things you read on the rest of the threads on this forum. The cost of a school is less than a good scope and will improve your shooting much more!
