Zep 0 #1 December 10, 2009 I have an old .22lr semi automatic with a 23.5inch barel that I want to shorten by 6 inches I typically use RWS subs and a suppressor. I normally shoot at around 40-50 yards, sometimes out to 80-100yards By reducing the length will I lose much accuracy/stopping power?

SkyChimp 0 #2 December 10, 2009 shorter barrel means less velocity and accuracy. Does anyone else find it funny that we made a SPORT out of an EMERGENCY PROCEDURE?!?! Quote Share this post Link to post Share on other sites
Zep 0 #3 December 10, 2009 That I know, I was more wondering if anyone had experience of using a shortened barrel. (not actually the cutting of the barrel, that I'll do in a lathe along with crowning and re threading for the suppressor) My thoughts were more along the lines of I'll lose around a quarter of the twist and how will that play on the accuracy/velocity also as it's a semi auto will it have problems recycling as that I use subs.

JohnRich 4 #4 December 11, 2009 If you ruin the accuracy and functionality of this rifle, are you going to cry over it's loss? If so, don't do it. If it's a rifle you don't care that much about, then go forth and experiment. Why is a six-inch shorter barrel that important to you? Also, that would make the barrel 17.5", and I think the BATF requires a minimum of 18" to be legal. Do you want to spend 10 years in prison over a .22 rifle? Or have your wife shot to death by ATF agents, like they did with Randy Weaver? Quote Share this post Link to post Share on other sites

Belgian_Draft 0 #7 December 11, 2009 Quote I have an old .22lr semi automatic with a 23.5inch barel that I want to shorten by 6 inches I typically use RWS subs and a suppressor. I normally shoot at around 40-50 yards, sometimes out to 80-100yards By reducing the length will I lose much accuracy/stopping power? I found out many moons ago that 16 inches is pretty close to the best length for velocity. Depending on the particular cartridge you may gain just a tad (not much, though) by going longer than 16, but in many cases velocity actually dropped off slightly. This is because there is so little powder to burn that it all is consumed very quickly, in the first few inches, and the gases just don't have enough energy to overcome the friction and continue to accelerate the bullet much past 16 inches of bore. Contrary to "common knowledge", in a .22 a shorter barrel can be much more accurate. This is because most .22 barrels are pretty flimsy to begin with so shortening them really reduces the effects of vibration. I say go ahead and cut it if it is legal and that is what you want. You will be pleased with the results. Just make sure to get a very good and precise crown. That will make or break the accuracy of the finished product.HAMMER: Originally employed as a weapon of war, the hammer nowadays is used as a kind of divining rod to locate the most expensive parts adjacent the object we are trying to hit.

Zep 0 #8 December 11, 2009 John, Here 17.5" barrel is perfectly legal, Suppressors are legal. I would be a little upsett if buy shortening the barrel ruined the gun, it's my favourite gun for shooting Mink and ferrets being that it is so quiet I can knock down a mink and another before they realise that anything is amiss. The total length of the rifle is 48" 8" of that being the suppressor, it's to long and badly balanced for using in brush. I think that losing 6" off the barrel would lose the front heavyness and make it much eaiser to hold steady whilst aiming. I know that in a perfect world I would have time to use a tripod and the little critters would stay still to be shot at, but we don't live in a perfect worldBelgian_Draft. what you say does seem to make sence, I think what I'll do is wait till Spring and the local gun fair, buy an old CZ or similar (50€) and experiment with that. I concur with what you say a well crowned barrel makes all the difference, I use a brass round headed screw in a drill with a little lapping paste.

Correct - for shotguns, it's 18" for the barrel and 26" overall.Mike I love you, Shannon and Jim. POPS 9708 , SCR 14706 Quote Share this post Link to post Share on other sites
LouDiamond 1 #11 December 12, 2009 What kind of gun is it that you want to do this to? A good example of a short barreled 22 that is still very accurate is the Ruger 10 22 Charger. Technically it's a pistol but you can get regular and charger 10 22 barrels that are already threaded for suppressors for a couple hundred bucks. Suppressed 22s are like shooting a pellet gun and a blast for plinking. Here is a purpose suppressed one."It's just skydiving..additional drama is not required" Some people dream about flying, I live my dream SKYMONKEY PUBLISHING Quote Share this post Link to post Share on other sites
Zep 0 #12 December 12, 2009 Its a French "Unique X51 bis" Unique armes did make a 17.5" barrel version of the X51 but they went out of buisness years ago, and I've given up trying to find one on the second hand market. The rifle has a neat little feature where you can turn a knurled screw and it will hold the breech open after firing. not seen that on other semi autos Gone fishing Quote Share this post Link to post Share on other sites
Ron 10 #13 December 12, 2009 You should not lose much if any accuracy at the range. I have a 10.5" AR that I can still hit out to 100y with. Now.... Personally if this is a fun gun and you like it... I'd just buy another that is setup like you want.
