I'm hoping it shoots as well as an acquaintance's SURREY barrel marked MK2 .
If it doesn't shoot factory ammo, don't be discouraged.
If the ways aren't tight, glass bed the action with the stock and things will come together very quickly.
I bought and gave a home cut down MkII to a young fellow last fall.
It had some serious accuracy issues, mostly becaue neither he nor his father knew how to properly clean their firearms and took the MkII apart, screwed up the ways and ended up splitting the fore end.
I glued the fore end, bedded the receiver to the ways with Acraglas, then cleaned the fouling from over 80 mixed lot surplus rounds "Dad" was given and all shot off one Saturday afternoon. (I know you won't do this and have probably seen similar abuse)
"Dad" liked to drink a few beers while he went shooting. Great way to teach a youngster.
Anyway, thankfully that 44 dated Winchester brass was Boxer primed and non corrosive, because it was close to a month after their shooting lesson that the rifle was brought back by an "indignant" Dad.
I asked the Dad if I could take the 14 year old to the range with me to sight in the rifle and emphasized PROPERLY.
I took a box of Winchester Blue Box 174 grain and a box of hand loads put together with a recipe that will shoot acceptably for hunting in most rifles, loaded on the brass, fired in that rifle he gave me.
The rifle was fitted with a fixed 4X US built Weaver and it was sharp/clear.
The Winchester Blue Box shot a bit high, after bore sighting but only took a few clicks up to bring it 1 inch above POA, with a 2 inch group at 100 yds.
The hand loads shot almost to the same POA but slightly lower. The groups were tighter, slightly over 1 inch, if we did our part.
The young fellow was recoil shy and anticipated every shot with a bit of trepidation, causeing a flinch.
We fitted a recoil pad to the butt and took him back to try it out. It was a take off Sorbothane pad from a shotgun, so was easily fitted to his butt stock after we cut it flat.
His groups tightened up to right around 2 inches with both factory and hand loads.
We went back and he properly cleaned the rifle, then reloaded all of the ammo we had shot off.
I gave him a Dewey cleaning rod, that I had from an estate sale, along with a bottle of Wipe Out, brushes, jag and patches.
He came back to me this spring, with a Cooey #60 that his grandfather gave him and we cleaned it up. The stock was beat to hell and there wasn't any finish that was visible. I don't think that rifle was ever cleaned from the day it was purchased.
After cleaning the crud from the bore, the rifle shot well.
Oh, the MkII was locked in his personal closet, because his "Dad" wanted to use it to hunt with and the young fellow didn't want it screwed up.
I don't think his Dad really minded and was pulling his son's leg. I think he was quite proud of him and how well he shoots and takes care of his firearms.
The Dad must be doing something right with the youngster, because he came over one Saturday and helped with a bunch of clean up and split some firewood for me.
Nice young fellow.
