10/22 Smithing

[rlandrum]

I picked up a 1-12 twist match barrel off ebay. I was thinking of using this in the sporter class during my next match. I've never done any 10/22 gunsmithing and was wondering if there was any caveats I should be aware of before I begin.

Thanks,

Rob

I f you bought a barrell for a 10/22 as a replacement it is probably not a 12 twist,, most are 16 twist. Installation is easy.. Neil

I noticed most were 1-16... This one was listed as follows:

Stainless steel .920 target/match grade barrel 12 hole port with recessed target crown
Match chamber
This barrel is un fired and brand new.
1-12 twist rate button rifling

I've also picked up a ProMag stock, which isn't exactly sporter legal, but my current stock is for tapered barrels.

Any good references or techniques for bedding the 10/22?

i have had no problems doing the work myself on 10/22s. i am currently working on one now. planning on using a kidd 16.5" barrel and another hogue overmold stock. what is the barrel maker that you bought?

 

[rlandrum]

The seller claims the brand is "Outdoors" and that it is in fact 1-12 twist.

hmmm, never heard of them

hmmm, never heard of them

That makes two of us, and even google is stumped.

We'll see how it shoots. I didn't want to spend a ton of money on a Sporter Class gun. If it shoots well, great. If not... Anything is better than the barrel I have now, which probably has 50000 rounds through it.

Im no expert but that twist it too fast for a 22 long rifle. Stick with major brands you'll be better off. Kidd makes some very accurate 10/22 barrels. I had a Green Mt that shot 3/4 at 50yds. Buy once cry once. I built a all out Ruger and was never happy with its accuracy. Should have just bought a complete rifle.

1 in 12 isn't too fast for a 22 long rifle, just different from the norm. The fastest twist barrels chambered for 22 rimfire that commonly show up are 1 in 9, made primarily for the Aguila 60gr SSS round, which is admittedly a bit of an oddball. In the 1 in 9 barrels, "normal" 34gr to 40gr 22LR rounds tend to shoot more accurately than the 60gr SSS round shoots in 1 in 16 twist barrels. I wouldn't worry about the 1 in 12 twist barrel; put it together and see what happens - if it shoots, fine, if not, back to the drawing board. Also, grab a patch, a cleaning rod and a magic marker and see just what the twist is, just for kicks. Keep us posted.

I bought a Hall BR rifle from an experimenter. It came with a couple of 14 twist bbls. What I have found is that the fast twist bbls really 'take off' on you when the condition changes even a little bit.

I think what is happening is that the bullet is spinning a lot faster and this adds more vertical component to any condition change. Whereas a 16 twist might move half a ring up or down depending on the new condition the faster twist would move a whole ring or more vertical plus a little extra horizontal component.

I am eventually going to fit up a BR spec RF bbl to an AR15. Something around .850 diameter, about 24" long and a tuner. I will probably use a Bentz reamer although I may try a BR reamer at first. It will be interesting to see how it works out.
