Several years back, the ISRA was offering a "new shooter clinic" to increase interest in service rifle competition. I believe it was free, or a small donation, regardless I thought it would be a good way to spend a Saturday. You were to bring rifle, ammo, and a sling they would provide the instructors. We shot iron sight at 200 yards prone, kneeling, and offhand.

Prone I was pretty good (actually better than expected), kneeling I was ok, offhand was the most humbling shooting experience ever. John from WOA was one of the instructors. I was a little bummed I didn't get paired with him otherwise it was a great experience. From that I determined I'd use any and all available resources to improve my accuracy.

FWIW I was running a untouched green label HBAR. Some work on the trigger, or a new one, would have made a huge difference.
