22 LR Barrel Length

If the best length is 16 to 18 inches, why do manufacturers make longer(20 to 22 inch) barrels? does this not create bullet drag and slow the bullet spin and velocity?

Welcome @jrnovemberrain69

I moved your thread to a more appropriate area

"....the best length is 16 to 18 inches"

what makes 16" to 18" the best? Best what? Best velocity? Best accuracy? Best balance or weight? Best for tuning?

I have rifles with a variety of lengths. They're all good shooters. I prefer the ones that are 20"-24". I have shorter and longer barrels that shoot just as well. It's probably more how they look and feel

I have 3 BR rifles that have barrels that are 24 5/8", 25", & 25 1/4". They're by far my best shooting rifles. I also have an old Rem 513T with a 28" barrel that shoots way better than it should. But also have a Anschutz 1416 AV with a 18" barrel that's ridiculously accurate for a factory rifle

I've read one advantage of longer barrels beyond the max velocity length (somewhere around that 16-18 inches) is it lowers muzzle velocity spread. Faster bullets slow more once past point of max velocity than slower bullets. Which results in the velocity spread being lower with a longer barrel.

There are many factors to accuracy of course.

Shorter rifle barrels often yield higher muzzle velocities but that in itself doesn't make them better. But it's worth noting that shorter barrels don't always give faster ammo speeds than longer barrels.

Newer shooters and those who may not know better often intuitively assume that faster .22LR bullets are more accurate than slower ones. Muzzle velocity (MV) with .22LR has no direct relationship to accuracy. In fact the best accuracy is produced with .22LR match ammo which is typically on the "slower" side of MVs, around 1060 - 1070 fps.

When shooting at fixed distances (for example at 100 yards) differences in amount of vertical drop between faster and slower rounds is meaningless. Sight/scope adjustments take care of that.

Another small consideration is that slower .22LR ammo drifts less in the wind than faster .22LR rounds. While intuitively it may be the opposite, slower ammo is better when it comes to wind drift.

The "best" barrel length is determined by its use. It shouldn't matter a whit if it's MVs are a little faster or slower than those of another barrel. Most shooters who shoot competitively with accuracy in mind typically have barrels 24" or more in length.

Hello all. I realized after my post that I skipped introduction and went right to the question. I am not what anyone would consider tech savvy. Thank you for moving post to here. I live in Wisconsin and have been shooting just for fun since I was a kid. Life got in the way for a few years and I fell away from it. Started shooting non seriously about 2 years ago. Mostly handguns but some rifle. Only 25 yard max indoor. Looking to purchase a bolt action 22LR and sometimes overthink things. What I meant by "best" is what I understand to be full powder burn and after that bullet drag and how much that may affect bullet spin, and therefore accuracy. HOLY COW, 27 and 28 inch barrels. I thought CZ 457 American is quite long at 24-25 inches. Anyway, thank all for the responses. I am impressed with RC already.

I figured you meant most efficient.

No argument with that. Rimfire powder is pretty much totally consumed in a 16-18" barrel and little is gained beyond that (from what I've read).

As others have already written I choose my barrel based on use. Tony Kidd stated that the best accuracy is gotten from his heavy 20" non-fluted, non threaded barrel so that was the first I bought, except I had mine threaded. But that was for the bench. My field barrel was his ULW 16" barrel. The difference in rifle weight (same receiver) is >12# and 6# 8oz. No way would I carry a 12# rifle in the field unless I absolutely had to.

I'd assume for some, say in the pre-chassis era, to better balance and add weight out front the longer barrel would help for some sports. Or, say the 22lr was built as a 1:1 trainer for a larger caliber and they wanted to overall feel to be the same. Now, a shorter barrel can be used, will get similar velocities and the like for peactical purposes and the package will be more compact.

More pennies for your thoughts. Short barrels are good for hitting things quickly, What I call field shooting. Long barrels are good for hitting spots. Ie bench rest . But the stock configuration is important also. A small compact stock imho doesnt work well with a long heavy barrel , I have a 17 inch heavy taper gm barrel in a barracuda style stock that is marvelous off the bench . Way better than when it was in a LVT stock.
But thats for me , cause I shoot better with a barrel heavy balance off the bench. In the field I shoot better with a neutral balance.

I agree. My SG in bench configuration was tried with a minimalist buttstock and I just didn't like it. I put the Luth-AR buttstock back on and it was "Ahhh, so much better.". But would I want the target buttstock on it when it's in field configuration? No, absolutely not.

I always wanted to try one of those!

I have everything between 16” and 25”.

Optics, triggers, ammo, and bag position seem my biggest limiting factors. They all shoot about as I expect for whatever combo I’ve got going on, and about the same as others from what I read. I do know some very methodical people who can achieve that last .2” of excellence with patience, practice, and breath control.

I think it’s interesting that Kidd offers 20” bull barrels as standard on their Supergrade. Maybe there are manufacturing/economy reasons for that, but I also wouldn’t be surprised if they deemed that the sweet spot across the widest range of variables.

I believe that may be true with centerfire cartridges but not often rimfire. 26" is too long for rimfire.

I pick the barrel length and profile by what I want the rifle to feel like. IMO any barrel can be accurate, depending on how it is made more than anything.

Just built a 10/22 for speed shooting with a 16" pencil Faxon barrel but my target guns all have 20" barrels. Just bought a Shaw 18" bull barrel I want to try and compare it to my 20" bull barrel. I own an LVT with 20" factory taper (match) barrel that shoots great.

There's more to barrel length than just velocity. True the maximum velocity might be reached at around 18"-20", and you will begin to slow the bullet down as your barrel gets longer. But you could add another 10" over maximum and not lose maybe 50 fps, so it's not like your long barrel is putting the brakes on at anything over 20" long.
I don't own a .22 rifle with a barrel under 24" and some of my most accurate I own have 30" barrels and will outshoot any 20" .22 rifle I've shot against. But most of those are equipped with both target scope bases, and also quality target iron sights. And with iron sights of good quality the long 30" barrel really shines over a stubby 20" barrel. I also like the balance better for offhand shooting as it just hangs better with the extra weight.

But they do. Eley have used Anschutz 54 test rifles for many years. These have 26in and 27.2in barrels. Going by social media, they now have some Walther KK500s: 25.6in or 27.2in barrels. Way back in the day they had BSA, Vickers, Remington, and Winchester trst barrels: 28in-29in

RWS test with 25.6in barrels, quite possibly Walther, although Bleiker would meet that spec. RWS R 50 | RWS Ammunition

EDIT Lapua and SK both list barrel length for MV as 660mm/26in. https://sk-ammunition.com/products/rifle-match/

If you meant US companies don't use 26in barrels, that may be true. But it's not what you wrote.

Im old school and many of the old desirable rifles have long barrels and are extremely accurate. That is why competitive shooters want them. Those old timers knew what they were doing and were real craftsmen without any of the computerized machinery to do it. In this day and age I wouldnt doubt that some bean counter is figuring out how many extra barrels and profit they can make by telling everyone that a 20" is all you need. There is much to be said about the extra stability a slug gets in that extra distance.

All interesting info. I recently watched a video where they started with a 48" barrel and gradually cut it down and recrowned while testing velocity. There was not a linear decrease in velocity. And at some points it actually increased. I believe the conclusion was they did not know why. Some ideas but nothing concrete. It was , nonetheless, very interesting to see. Moving forward I will not overthink things and simply purchase whatever looks good and feels right to me. It's great to have choices.
