Big Dog Posted May 17, 2006 Report Share Posted May 17, 2006 Hi guys. I need some of you old dogs to click into this debate. I have a question about barrel length: on a .222 will there be any difference in accuracy and o/a performance between barrel length at 20" and one at 23". Power burn off and all that stuff. A 20" barrel with a T4 will be short that a 23" barrel. Seems nice but would I regret it> On a 6.5 x 55 would a 20" barrel be to short? Would the power burn up? Would you loose accuracy and would it hammer the shoulder off you?? Or would it be peaches and cream. What is the wisdom out there. Quote Link to comment Share on other sites More sharing options...
The Bear Posted May 17, 2006 Report Share Posted May 17, 2006 With the 6.5, i can hardl see much difference between a 20" and a 22" barrel, its not a high velocity calibre so its fairly unimportant. With a .222, well im not sure, the case capacity is relatively small so i dont think you will have complete powder burn problems and you can also move to slightly faster burners if you wish, again, its not a particularly high velocity calibre and you dont have to meet certain velocity or energy goal to be within the law in said calibre either. As regards accuracy, well, i doubt you would notice any difference. Barrel length is mainly a concern for "Overbore" cartridges such as 22-250, 220 swift, 243, and big magnums such as 7mm Mags and Remy Ultra Mags etc where the whole point of the cartridge is to give you more powder/velocity which needs that long barrel to give a good burn. Some small cartridges such as 6mm Br can benifit as you can stretch the velocity a bit with a longer barrel. Look at 6mmPPC, probably the most inherrently accurate cartridge in the world ever and most of those dont use long barrels though, c.20" maybe. I would always be tempted to leave a good gun "be" myself, dont mend what isnt broken, but if you wanna make a nice "4x4 CAB" gun for foxing, try it out. Programs like quickload will give you definitive data on load dynamics but i wouldnt expect to loose more than 50 -75 fps in the .222, maybe 75 in the 6.5? Remember though, the 6.5 punches above its weight due to superior B.C. and sectional density in the bullet, its never been a high velocity round or poky with the recoil. Im not sure if mine is a 20 or a 22 but it gives me 2950 fps with a 120 grain projectile which is plenty in the UK. Quote Link to comment Share on other sites More sharing options...
Big Dog Posted May 17, 2006 Author Report Share Posted May 17, 2006 Thanks The Bear. I am not cutting a gun, I am in the market for a .222 and can get it in 20" 22" and 23.5". The 6.5 I don't have but would like to put one on next year. I appreciate you input. I must get my head around Ballistic stuff better.

deadeye ive Posted May 17, 2006 Report Share Posted May 17, 2006 Is the .222 getting any nearer BD ?....................FWIW if the lenght of barrel feels comfortable with your shooting style then go for it and don't worry to much mate ...........I'm talking factory prepared shortened barrels here ,not DIY via a gunsmith Quote Link to comment Share on other sites More sharing options...
Frank Posted May 17, 2006 Report Share Posted May 17, 2006 Big Dog, I have a CZ .223 with a 22 inch barrel and to me thats a wee bit short and in the begining i thought it might effect speed ect. But, as you can see from my posts, it does not. I know another fella that has a T4 on his CZ, the barrell is down to 20 inches and has no effect on the rifle at all. The 6.5 should be fine aswell. How is the firearms appllication coming on for the .222 anyway? Quote Link to comment Share on other sites More sharing options...

Frank my cz has a 23 inch barrel, as im having a T8 fitted at the mo he's gonna take 3 inches off it to bring the can a little closer to the end of the stock (cosmetics) He said it will make very little difference to the performance, i hope he's right Quote Link to comment Share on other sites More sharing options...
miffy Posted May 17, 2006 Report Share Posted May 17, 2006 I had the barrels shortened on my .22/250 and .308 both were shortened to about 17" due to the vaimeco mod that i had fitted. the accuracy was not affected at all Quote Link to comment Share on other sites More sharing options...

That is certain to loose a fair bit of velocity. It still killed a few foxes at 300 +yards and grouped less than 1/4" at 100 yards what more does anyone want??? Chrono'd it at over 3600 with 50 grain pills Quote Link to comment Share on other sites More sharing options...
mry716 Posted May 17, 2006 Report Share Posted May 17, 2006 Thats no use Miffy - get a Middlestead and run them out at 5278fps http://www.reloadersnest.com/detail.asp?Ca...100&LoadID=1147 Quote Link to comment Share on other sites More sharing options...

SPEEDY Posted May 18, 2006 Report Share Posted May 18, 2006 On a 6.5 x 55 would a 20" barrel be to short? Would the power burn up? Would you loose accuracy and would it hammer the shoulder off you?? Or would it be peaches and cream. My Remington Model 7 in 260rem has a 20" barrel and I can get a 120gr pill going at 2900fps and that’s plenty quick enough for most game that I go after. An extra 100-200fps only makes a difference on the range or hunting game past 350m other then that as the saying goes "Dead is dead it doesn’t come in degrees" Quote Link to comment Share on other sites More sharing options...
Big Dog Posted May 19, 2006 Author Report Share Posted May 19, 2006 The FAC not through yet but it should be moving by next month. 6 mth wait Dead-eye yes this would be a factory gun Quote Link to comment Share on other sites More sharing options...
