Don't know the guy but I'm sure, with his background, what you are taught will be sound. Next time I recommend Randy Cain of Cumberland Tactics. He's the best I've seen for new shooters (great for not-so new as well) He has a range a little north of Tampa FL. Its about time for me to attend his Practical Rifle class again.
Range tips? Pack a lunch. Spend the money for a Mag Lula loader. Your fingers will thank you.
