Ok here's my "take aways" from the clinic.....
I already had my rifle tuned and tweaked by the Doctor well before the clinic, so there wasn't too much more to do...(trimmed some springs, etc) Until I tried to break down the rifle and the trigger group would NOT come out! No way! But after handing it over to Thomas, his expert eye spotted the problem in seconds: a roll pin had walked out just a tiny bit, blocking the trigger guard "hinge" from swinging open. I doubt I would ever have figured out how to correct it but the Doc knew, and all was well again!
Then, I was able to pass this knowledge on to another shooter who had the exact same issue later in the day.
The weak point of my M14 was the irons, (I should say, me using irons) but I wasn't concerned since I was going with an aimpoint micro on an arms 18 mount. ..... That is, until I started to get stovepipes every time I mounted the aimpoint!
Off came the red dot, and now I had to go to irons! Luckily I changed over to Italian rear sights from Hungry.... And boy does he know how to use them!
I zeroed at 25, then re-zeroed the elevation knob for 300 yds, but i only had 1 click of "down" remaining. But how to shoot at a hundred with only 1click of adjustment? Hungry just said, if you shoot right on the bull, you'll print 5" high at 100.
Dammed if I wasn't! amazing! 6 o'clock hold got me on target.
P mags (I was shooting with my AR on day 4) are very reliable under stress. zero stoppages or feeding problems. All the ones I used were "5.5" mags.
LAR mags were not bad, but they did have some issues after being stressed and abused in the heat...... And from Hungry stomping on them every chance he got! Lol
I was awed by Billygoat's Isralie mag change demonstration! Wow!
What did you-all learn?
