Re: free float 1022
I get the best accuracy from 10/22s by freefloating the barrel.
There are two things that you have to overcome to free float a barrel. The first is barrel droop. Barrel droop is caused by a loose fit between the barrel and receiver. The barrel should not wobble when it is installed in the receiver. Using an adjustable V-block only masks the symptom by swapping a droop for the inverse. You still have a bad fit between barrel and receiver.
The proper way to fix droop is to either get a barrel that offers a tight fit to the receiver, like a Kidd, or you can turn down the barrel a tad bit and sleeve it to get a proper fit. Going with a new barrel is more cost effective, unless you are handy doing machine work.
The second problem with free floating the barrel is that a stock receiver only has a single attachment point, which leaves the back end free to move up and down. You can fix this by either getting a receiver that has a rear tang or you can cut a locking lug into the back of the receiver and then bed the receiver to create a corresponding lock in the receiver.
This is what I did to mine. I first cut a slot in the rear of my receiver...
I then cut a slot in the forward lug. Once bedded, this will serve to make sure that the action goes into the receiver the same way every time.
I then made a pillar and bedded the front of the receiver. Note the lug left by the groove that was cut.
I then bedded the rear of receiver. Again, note the lug created by the groove in the receiver.
I am now running an 18" bull barrel that is completely freefloated and it shoots great. I get no movement at the back of the receiver when I push down on the barrel. I am now going to use this rifle for 100 and 200 yard F Class type competitions, my reasoning being that once I get a favorable condition, I'll be able to put ten rounds on target much more quickly than I could with a bolt gun.
Just FYI, I found that the above works best if you remove the barrel while doing the work. Also take care not to put too much stress on the V-block screws. I run about 10 in-lbs on them. The V-Block screws shouldn't be used to hold anything together. The only purpose they should serve is to keep the barrel from moving forward from the bolt slamming against it.
I've shot groups with my rifle with the V-block not installed and it may shoot better. I can only get about five rounds before the barrel starts to move forward, but testing indicates that running without the V-block may be the thing to do.
I'm keeping an eye open for a Ruger receiver. I want to try permanently affixing the barrel to the receiver so that I don't have to use the V-Block at all.
