If you need to rebarrel your Garand, you might consider using a chrome lined barrel.
Criterion makes chrome lined Garand barrels for Fulton Armory and these barrels are available in .30-06 and in. 308.
These barrels are also as accurate as non-chromed barrels. And the chrome lined barrels are easy to clean and will last a very long time.
If you want to rebarrel your own Garand, chrome lined barrels are a good way to go because you will not need an expensive pull through chamber reamer.
Pull through reamer kits can cost around $200 whereas a chrome-line barrel costs an additional hundred bucks.
The chrome lined barrel is fully chambered and you can only adjust headspace by using different bolts.
The shortest Garand bolts are WRA followed by Springfield-12 bolts. If you install a chrome lined barrel a WRA or SA-12 bolt will drop in and headspace properly.
With other Garand bolts, you may have to lap the bolt in and 65 series bolts will be too long to fit.
So with a chrome lined barrel, just tighten and time it to your receiver. Then drop in a WRA or SA-12 bolt and you should be golden.
Some people are afraid of trying a chrome lined barrel because they can't be finish reamed. So get a short bolt and don't worry.
