He's got 5 or 6 of these videos out now and his son is in #3 or4. The only thing I don't agree with is how he shoots prone in every video so far. We don't always have that option so I'd like to see him shoot from a tree stand or using a stump or fence post for a rest. Those are real life shots I've had to make frequently at 300 to 400yds.
I agree, but with a caveat.
It might just be that the ability to go prone, with a rear support, is his "requirement" for "X" distance. IMHO it's one of the things "learned" from practice;
what support/level of stability, combined with the conditions is required to make a shot at "X" distance.
For instance, in my case:
Off hand.. 100 as long as it's not gale force winds blowing me around, not much time needed
Sitting unsupported: out to 200, same wind as above, not much time needed
Prone unsupported: 250, not much time needed
Prone supported backpack: 300-350, BDC reticle, hold on hair, Leupold Duplex crosshair junction
Sitting supported, tripod on a bag, variable winds, more time needed, use dope card or BDC reticle <15MPH: 400
Sitting, tripod, rifle clamped in, rear support (really a backpack in my lap) light variable winds <10MPH, more time needed, dope card : 550
I'm pretty good prone supported out to 600+ with stable winds, but I need time to get in position, a wind reading, maybe even a glance at Strelok with current weather entered.
The problem is, the vast majority of hunters aren't going to "get there" due to range limitations, practice time or desire. Equipment is the easy part, and not really that expensive, but learning you're capabilities takes practice. Go to your average public range and just watch guys shoot.. it's rare to see anybody not shooting from a bench.
Honestly, spend enough time shooting past 500yds and 300 and under becomes a given with your average bottle neck cartridge deer rifle. The conditions have limited effect and you're working with a 3MOA kill zone on a deer. It takes about a 16-17MPH 9 O'clock wind to push a 2800FPS bullet out of a kill zone at 300. The key in IMHO is to adopt the "train as you fight" mantra and make your practice more challenging than your average shots on game.
Off-hand is a great skill, but the vast majority of shots on game I've taken I've been supported by "something". Usually, the further an animal is away, the more time you have, and I've not had much of an issue dropping into a sitting/kneeling position, leaning on a tree etc. I've adopted using back-packs with frames because they make excellent rests for hasty sitting positions. About the only time I know I'm going to shoot off-hand is while still hunting and drives in wooded terrain. For both the ranges are limited.
