100% in agreement on the Remington Thunderbolts...
22 cal bore question
- Thread starter Narragansett
- Start date
A friend of mine re-lines barrels. PM me and I can connect you.
----
The only .22 LR barrels I have seen honestly shot are were on match guns or gallery guns that saw tens of thousands of rounds down the bore.
More often, wear in a .22 LR is due to large amounts of improper cleaning from the muzzle and/or with a segmented rod.
I'm not inclined to clean a .22 LR until the accuracy starts to fall off, meaning no more often than every 500-1000 rounds.

OP
You see the prices for smoothbore Model 510's? Up to 950
Maybe 8mm OD,,that's the size they adv Redman's 22rf liners for being.
They are 5/16 d (.3125) in 'Merican measurement.
I used an 'O' letter size drill (.316) brazed to a length of drill rod and a pilot ground onto the tip of the drill for boring out the old bbls.
TJ's Liners 22 liners are the same dia, or at least they seemed to fit right in that same dia bored hole. I never made up a different tool when I started using those.
TJ's liners are hammer forged
Redmans (Brownells) are button rifled.
Numrich's liners looked like they were rifled by pulling a bent and sharpened coat hanger through a piece of automotive brake line tube a couple times.
I've always epoxied them in. But using Loctite (Bearing/Shaft Retaining) seems to be the most popular method of late. Though some just use the Red thread locker mix.
You still have to chamber and headspace the project. Cut any extractor slot necessary, maybe a feed ramp on some.
Cut and crown the muzzle. Then often reblue the bbl.
It can be quite a project beyond just boring out the old bbl and sliding in the new liner.
Centerfires go the same way but the liners run up in OD size quite quickly.
Boring out a bbl to a 1/2" or 5/8" diam hole is not that easy w/o some equipment help. The 'ol Black&Decker kind of meets it match when trying to do that kind of job.
Breaking off your extra long drill down in there is a real possibility too. Then there's some real hard thinkin' to be done before proceeding with the program.

I remember this advertisement years ago for the Remington Nylon 77 .22lr semi-auto rifle. 100004 wood blocks shot at a rate of 1000 per hour. If you read the whole ad on line , it'll tell you the bore was as new when cleaned after the marathon.

I don't think so if waxed bullets (like modern bullets are lubed) are used. In fact, using these bullets prevents leading. And prevents rusting. I almost never clean the bores of my .22s...I think cleaning degrades accuracy until you foul the bore again.
I bought an old Meridan pump .22 that had the bore ruined. I don't know how old it is but I had to reline the bore.
Had liner installed 25 years
Ago it cost $65 back then.
It is in a Stevens mod.44
With a Fecker scope
I am sure it shoots better
Than when it was new
.
OP
Was the bore rusted or shot out?
Out side of gun good inside
Looked like dirt road.
This is heavy barrel half round
Half octagon, the liner was made
By Walther, it is very accurate.

Many gunsmiths use Loctite (the strongest one) for cementing bore liners in place. Lothar Walther .22 liners are the best.

Recently quoted $225 for relining a 22 rifle.
