Will your 223 5.56 shoot 62 grain bullets accurate at 600 yrds the rifeling twist is 1in9 How heavy of a grain can i use with out wearing the crome lined barrel?
1 in 9 is actually the ideal pitch for the 5.56x45 SS109/M855 cartridge. The reason the military went with 1 in 7 is because it could fire 62 grain ball ammo and 64 grain tracer ammo to matching flight characteristics. You're perfectly fine with the barrel you have.
As for the chrome lining, that all depends, and I personally advise most civilian shooters not to bother with it. Several companies offer chrome lined barrels, but most of them don't line their barrels to the actual military specifications (in spite of their claims of being mil spec). This often results in the chrome lining being substandard, eventually flaking off, and causing a reduction in accuracy. You should also note that non-chrome lined barrels are typically more accurate than chrome lined barrels, because of imperfections created by the chrome lining process.
Some manufacturers of cartridges up to 75 grain actually recommend a 1 in 9 pitch. It will not, however, properly stabilise the 77 grain cartridges, nor the 80 grain .223 Wylde cartridges (which require a specific chamber, anyhow).
Also note that, while .223 Remington and 5.56x45 are dimensionally similar, they are not one in the same.
The longer the barrel allows several things: Higher velocity bullets ( From better containing of burning propellant ) The longer barrel help the bullet become and stay stable thus creating a more accurate firearm The higher mass of the long weapon helps control and direct the recoil The longer weapon allows more stable and accurate aiming The longer barrel allows the use of flash suppression and gas redirection with out risking the operators health
Not necessarily. A barrel shorter then 8 inches will have a hard time getting up to 300 fps, and anything over 16 will take up more air. If the barrel is stationary, a longer barrel will lead to greater accuracy, but if you are moving with a long barrel your shots will be less accurate then a regular one.
Each gun barrel has a unique spiral pattern which leaves an imprint on any bullets that are fired. It's my understanding that they can match up the grooves on the bullet with the grooves on the barrel of a gun fairly easily, even if the bullet is all mashed up and deformed from impact. Hope this helps! Dee
If a gun was parallel with the earth and was fired and at that very instant someone standing by the barrel dropped a bullet from beside the barrel, both bullets would hit the ground at the same time. Bullets start falling the instant they leave the end of the gun barrel. That is why hunters hold their rifles at an upward angle. It looks like the bullet will shoot up into the sky. The bullet…
Need information on J Stevens 410 double barrel side by side shotgun patented April 20 1915 Does not have a model number Top of the left barrel has 410 gauge stamped on it?
value will depend on condition. also is one of your barrel riffled for accurate slug? is it still operational and accurate? I have a Stevens 1915 410 with one barrel riffled and its in perfect working order, dead accurate, and its in the best condition I have ever seen for that time era. Mines been feeding the family for generations.
BB are inherently inaccurate. there is no best BB. The reason is the BB barrel is smooth and the BB tumbles as it is fired from the gun. Pellets usually are fired from a rifled barrel (One that has grooves in it) and they spin as they leave the barrel, making them more accurate. The only BB gun the I know of that spins the BB's is the Gamo P23, but you MUST use Gamo…
