Having your own place to shoot is a big plus. Much of the things taught in even the better courses is still designed for the square range and student safety ( lawsuit prevention ) and not a combative environment.
Just as an example the scans taught in classes.
I'd have to give it some thought to find specific training scars, but I have lost a measure of intentionality in my shooting just in general. I used to be very intentional and procedure-oriented in my practice. Deliberately scanning, reloading, moving, or whatever. Now, on the rare occasion that I actually put in some work, I just do whatever. Not always the same thing, either.
Lack of deliberate action may be as much or more a training issue than training scars. In some cases, if you've burned in suboptimal actions, you're still doing something. Sometimes something is better than nothing. Sometimes it isn't.
The last class I took with Coach I had a jam that I could not clear. I raised my hand and the range went cold. I had my BUG and should have dropped my primary and engaged the target, but you know range safety and all that. That would not have worked out well in a real life situation. Excuse me, I have a malfunction could we continue this gun fight tomorrow?
I had to disassemble the pistol remove the safety spring and detent and finish the class without a safety. I effectively turned my 1911 into a Glock.
You can scan pretty effectively on a square range. You don't have to wave your blaster around to use your eyes.
Solely shooting on your own private range can also go the other direction. Not shooting with others around can cause real issues with safe gun handling.
A lot of otherwise very good shooters have been benched or sent home from competitions and classes for muzzle
How would you scan your 6 and still keep the threat in your vision with square range rules?
Well then, you should have finished the course of fire, because at that point, it would have worked!I effectively turned my 1911 into a Glock.
