Resurrecting this one...
I still think I will keep the glass off of my service rifle, but for CMP Modern Military I thought it might be worth a shot to try again at the close up friendly distance of only (lol) 200 yards. Bought a decent mount and when the weather was too bad to even enjoy skiing I played around with position to find one that worked at least OK for all positions.
Off to the range today. No way to get there without 4x4- this is what the range road looks like
after it has been plowed:

If one of my kids did that, I'd make him come back for a do-over.
So here's the Modern Military upper that I pieced together with a Criterion USGI spec 20" skinny barrel and parts from the bin:

Yep, that's the infernal 1X-4X Vortex on top, just waiting to mock me with frustrating shots at my 100 yard range.
Here's a 5-shot group off the bench with my 69 grain Nosler Comp reloads:

So not too bad for the first time checking out the self built upper. Seems like reasonable accuracy for the platform.
Because I had a bunch loaded up, thought I'd try some of my 80.5 grain Berger reloads:

Very promising! This barrel & upper combo seems to like the same chow that I feed by Compass Lake heavy bbl upper.
Awkward for me from the bench (edit), but I thought I'd try this upper with a sling. I would not mind prone in snow, but I wasn't going to do slush so I slinged up on the bench. POI definitely shifted downward. Straight downward at least, but ~4" down. After a couple sighting in shots, back to the SR-1 target:

Ugh... I was thinking I was using consistent technique, but those two high shots were the last two I fired. Most likely culprit is 'me', but I still think it's possible that I could be having fits with the scope. Next trip I'll mount the carry handle rear sight and try with and without sling. Hope to get it sorted out before the Modern Military match at Pembroke.
