Rate of twist???

I have a rifle that does not have the rate of twist stamped on the barrel. Is there an easy way I can find out the rate of twist?

It is a .300win, and i would assume it is 1:12, but i would like to know.

A cleaning rod with a bearing handle. Use a snug fitting patch and jag. Mark the top of the rod with a felt pen and push it in till it has made one revolution. Measuer how many inches it took to make the one complete Rev. I would repeat this several times and kinda average the results.

Re: Rate of twist???

may not give you an exact one but it will be close, use a cleaning patch, or several, jammed really tight in the lands, mark your cleaning rod right at the muzzle and push it down the barrel (making sure it rotates as you do it) until you have made one full revolution. Mark the rod again at the
muzzle and measure the distance between the two marks. Should give you pretty close measurement as long as it doesn't slip too much.
oops someone beat me to it as I was typing mine

I feel it is best to check from the action end if posible. Cleaning rods can easily damage the muzzle crown. But I realze some semi autos or pumps this may not be possible.

X2 For Broz! When possible, I would NEVER stick anything in my barrel from the muzzle end....
