what rate of twist is best?

[Guest buttonhook]

I'm looking at upgrading the 10/22 barrel. I see it is offered in 1:16 twist and 1:9 twist. someone explain to me when to use what twist.

I would go with a 1:16 twist, that seems a more proper twist rate for the shorter (and lighter) .22 rimfire bullets. Most .22 rimfire target barrels I have seen are at 1:16.

IMHO, a 1:9 is too fast of a twist rate for a .22LR bullet.

I also see them in 1:18

The 1:9 twist is usually used for stabilizing heavier bullets like the Aguila 60gr. SSS rounds. If you plan to shoot lighter rounds or just regular bulk pack stuff, I'd probably go with the 1:16.

9 twist is for the heavier bullets and the only one out there is the Sniper Sub Sonic from Aguila. They are a very specialized round that I wouldn't recommend a purpose built rifle for. I have used them at various times and even had a rifle that shot them well. Problem was I could not find a use for them that warranted the extra cost. They do have a phenominal amount of penetration (16+ inches) but what are you going to be shooting with a 22 that requires that much.

The 16 twist is the standard for all 22 long rifles and shoots all but the lightest rounds well given you use quality ammunition.

The 18 twist are for the lightest 22 LRs and shorts (If your rfile is built to shoot shorts). By light I mean 32 grain or less bullet weights. Th 18 twist is used for "Stinger" barrels by various manufacturers. Because the Stinger and others have such a short and light bullet, at 32 grains or less, they require less twist to stabilize. I have been told by numerous people that the purpose built "Stinger" barrels shoot Stingers, as well as other hyper velocity rounds, very well when compared to the miserable performance they give in the standard 16 twist barrels.

If it were me I would get a 16 twist barrel because it will shoot the most ammunition accurately. As long as you do not plan on exclusively shooting the Aguila SSS or any of the "Stinger" type rounds 16 twist you want.
