Why not get the factory bbl tuned up? Ruger's barrels are capable of decent accuracy with the right chamber and a decent crown. I recently redid a bbl for a coworker, in a factory plastic stock, and it shot very decent groups. The better groups it shot at 50 yds were right around 1/2", some just under, some over, but very few over 3/4". All this with cheap ammo to boot. It is nice to keep the factory look but still shoot like you spent a great deal more on a bbl. Just my .02.
That's a very interesting post.
The accuracy you are posting is not bad for a re-worked Ruger barrel
(I had, however, VERY different experience regarding those).
A bad crown throws the accuracy away, I agree.
I'm not sure what you mean by the right chamber, and
I cannot imagine what kind of voodoo would work
on a chamber already cut,
unless the factory chamber is cut undersize
or too short (which is not),
but I don't expect you to share your trade secrets here.
Do your tricks work every time, on ANY factory barrel?
The reason I'm asking is because in my experience,
the bore is "bent" a lot of times, although the outer contour
dials reasonably if checked on a lathe, between centers.
Sometimes the bore is so "bent"
that is very visible with the eye
if you look thru the barrel.
I have cut many of those 10/22 barrels
(for shizzles, just to measure)
and I found that sometimes, on some of them
the bore is eccentric
as much as 3/16" (from my memory).
I doubt that there is anything to be done to make
that kind of barrel shoot reasonably.
But, if you feel confident that your method works,
then I'm encouraging you to start doing this in numbers.
A (fairly new) factory barrel sells about $15-20 on the EE.
You can make some serious money, considering
the 10/22 barrel crisis in Canada right now.
