SSS Posted February 19, 2010 Report Share Posted February 19, 2010 (edited) What are the benefits of a shorter barrel on a Rimfire other than making it easier to handle? I know it will slow down the projectile slightly, but does it improve accuracy? My CZ is 16" as it is, but someone mentioned having the barrel chopped the other day. I dont know what I will gain from it, but a lot of people do it and anchutz do a short barrel as standard. There was also a ruger 10/22 on here not so long ago with a 12.5" barrel. Can you enlighten me please. All the very best, SSS Edited February 19, 2010 by SSS Quote Link to comment Share on other sites More sharing options...
albob Posted February 20, 2010 Report Share Posted February 20, 2010 most have it done because it is easier and safer to manourve for use in a 4x4. some do it to cut the weight down. some do it to make it easier to use on a bipod(talking hmr mainly). as for acuuracy,i would say no difference,as it can shoot well at either long or short barrel because if shorter improved accuracy,we would all be getting the hacksaw out.cannot think of any other reasons. oh,some cut it off because of damage or rust to the screwcut/crown and decide to go with less barrel length. al Quote Link to comment Share on other sites More sharing options...
Billy. Posted February 20, 2010 Report Share Posted February 20, 2010 (edited) I fancy getting the hacksaw out on my S/A, as I never use it any more... Can someone let me know where I should measure from, so that I don't turn it into a sect 5 rifle. Oh and if I stick a sound mod on the end, does that have to be after the 12.5" or can it make up the barrel to the total length of 12.5"?

vmobiler1 Posted February 20, 2010 Report Share Posted February 20, 2010 12.5" maximum without a mod 12.5" would be minimum barrel length not maximum. . . surely??? Quote Link to comment Share on other sites More sharing options...
alexm Posted February 20, 2010 Report Share Posted February 20, 2010 (edited) The whole rifle has to be no less than 60cm overall and the barrel has to be no less than 30cm without the mod... IF the mod is removable. If the mod is permanently pinned to the barrel then it counts as barrel...

All the very best, SSS Rimfire Magic do Factory Barrels for the Ruger 10/22 from 14 inches long, so I believe! I am thinking of getting a shorter (14 inch) barrel for my 10/22 (When I get it, which will hopefully be today) purely to reduce the weight and to make it easier to handle from inside my 4x4, especially with a mod fitted! I am not overly concerned about the accuracy issue with a shorter barrel (If there is one) as it will be mainly for lamping which is fairly close range (20 to 30 yards) compared to daylight shooting (Out to 140 yards) which I use the 17HMR for!

Dekers Posted February 20, 2010 Report Share Posted February 20, 2010 Perhaps a very small weight advantage (more if you have a heavy barrel of course), but frankly the only advantage I see is ease of handling, especially in a vehicle! Rifles are notoriously difficult to handle out of your 4x4 so shorter makes it easier! Factory barrels available in 14 inch for sure, individuals have cut them a bit shorter! A shorter barrel does not mean better accuracy, it can possibly be worse! Quote Link to comment Share on other sites More sharing options...
stevethevanman Posted February 20, 2010 Report Share Posted February 20, 2010 You do loose some velocity in a .17 HMR, however you can cut down a .22LR to about 13" and the velocity not be effected With a .17 HMR..I would not go below 16", as that is still fine for vehicle shooting and you dont loose too much Fps, the amunt you loose is about 150fps. And to put it in context, in a 20" barrel, you can make up that velocity just switching from remington to hornady!! So if you have a 16" barrel with hornadys, its the same as shooting 20" with remmys, so really it makes no differance, I have found the groups open up about 1/2" with my 16", however I havent had it long and fouled the barrel in much Steve Quote Link to comment Share on other sites More sharing options...

SSS Posted February 21, 2010 Author Report Share Posted February 21, 2010 On that basis, I may well buy a new barrel or have mine chopped. Anyone know where you can buy stainless barrels for a CZ452? All the best Quote Link to comment Share on other sites More sharing options...

All the best Simple answer is no, but probably worth having a chat here........ Border-barrels.com Mckillopeng@hotmail.com Border barrels have a bit of a name for barrels, and Neil Mckillops rifles have won British championships!! Neil is a top man, done some work for me and a few pals, excellent engineer and his prices are very reasonable!! Couple of points though, CZ don't do a stainless barrel, theres are nickel, and even if you do find a stainless one it will almost certainly cost you more than the whole rifle did to start with!!

SSS Posted February 21, 2010 Author Report Share Posted February 21, 2010 Cheers dekers, I had a look on the website and I see what you mean, not exactly cheap. I will stick with the standard barrel and look at getting it shortened and re-crowned. All the very best, SSS Quote Link to comment Share on other sites More sharing options...
Vince Green Posted February 22, 2010 Report Share Posted February 22, 2010 The "official" line is that within reasonable limits barrel length has no effect on accuracy. With a scoped rifle this makes no difference. However, on a target .22 it is desirable to have the front and rear sights as far apart from each other as possible for maximum accuracy so target rifles have long barrels for the sole purpose of extending the sights.

Dunkield Posted February 22, 2010 Report Share Posted February 22, 2010 Everyone quotes an expert in these situations, one of the few people I let work on my rifles tells me 14" is the optimum for a .22 shooting subs. Mine was 21" and is now 14" and if anything is more accurate than it was before, possibly due to the new crown, who knows? TBH I don't care as long as it performs the way it does, it's irrelevant.

Good answer , I concurr .Harnser . Certainly some basis in that answer, ...who is this "official" line?? But this pays no attention to bullet stabilisation, which would also tend to improve in a longer barrel, nor does it take account of any potential extra drag in a longer barrel. People also keep on about propellant burn being over by 12-14inches or whatever, generally true in most RF, but that takes no account of the pressure still being higher behind than in front of the bullet even when the burn has finished, the bullet will continue to accelerate along the barrel but at a much reduced and diminishing rate after the burn, energy really drops off as the bullet leaves the barrel and the pressure dissipates. Botton line is, all these things tend to only make a marginal difference in a rimfire (not necessarily so in a centrefire), they would only be of concern to absolute top target shooters who tend to win by fractions of points these days as opposed to whole points back when I was a lad! Practice with your gun of whatever length, and just get used to what it does!! Jobs a goodun!! Quote Link to comment Share on other sites More sharing options...
macca Posted February 22, 2010 Report Share Posted February 22, 2010 Hi, Full burn of propellant in a 22 takes about 16 inches of barrel length. More barrel length allows the bullet to go to"sleep" before it leaves barrel. Most target barrels exceed 24 inches (My bench rest rimfire is 30" long). Many quality barrels have a 1-2 thou constriction (you can feel this when pushing a firm patch through a clean barrel) at the end of the barrel - this enhances accuracy - early BRNO's (these are now called CZ) had this quality. Cutting those barrels definitely reduces accuracy. I dont like cutting barrels, I have no problem full length rifles out of a vehicle. We usually have two people in the vehicle - driver and shooter.

Ozzy Fudd Posted February 22, 2010 Report Share Posted February 22, 2010 some people are just more used to handling shorter barrels than others, i prefer using a longer one myself... Quote Link to comment Share on other sites More sharing options...
