another no4 mki* refurb project

[ssgross]

Read that a thousand times over. The butt is proper for the single-step socket. My guess is it shrunk as it dried out in storage, and will come back after a few years in my almost constant 50% humidity in northern Virginia. I'll need to keep an eye on it though - loosen the butt slightly if I'm not going to use it for a prolonged period.

Went to the range, and like an idiot didn't bring any proper targets with nice big black bull to look at. best I could find in my bag was 2" orange stickers and the back side of a student's old calculus exam (they get recycled into targets when they don't show up to class to get them.)
Attachment 105597
I shot off a simple front rest only, with cheap ammo. The orange sticker barely stood out at 25 yds. Shot my final 8 rounds at 100 yds trying for a bottom hold on the white rectangle. I was all over the place as I screwed with the front sight, but last 3 shots were just left with about a 2.5inch spread as expected.

I slugged the barrel last night. Slug is tight until halfway from the muzzle, then it slips and feels like it moves freely toward the chamber. So, I slugged both ends separately several times each looking for inconsistancy, tightening the slug by tapping it between 2 brass rods. I get .304 on the lands, and .322 on the grooves everywhere. My borecam shows the first half of the barrel a bit more polished and than the latter half. A little more JB paste on the muzzle half might help out.

Thanks everyone for your input, help, and support. It's been fun - no I'm ready to do another one! If anyone wants to know - the target pic is from a free android app called Range Buddy. There is a better one called "Ballistic X" that does more than just measure targets, but it's $8 and it's not $8 better than the free one.
