Remington R-15 .223 18inch Barrel (Velocity)

[tom223]

I am shooting Federal V-shock .223 55gr Nosler BT out of my R-15 with 18 inch barrel,1in9 twist I don't have a chronograph to see what velocity it is shooting. On the box it say's 3240 which probably out of a 24inch barrel. If anyone has Chronographed this load or have some info on what the velocity might be it would be very helpful. Thanks Tom

You are most likely under or at 3000fps. Just a guess cause gun to gun it varies.

Buy a chrono.

My experience with a 223 is : you increase/decrease about 24 fps per inch of barrel length.

I have an R-15 with the 18 inch barrel. I found it very hard to get 55 grain handloads to get over 3000fps. I tried a lot of different powders and varying powder weights and never once got anywhere close to the so called standard velocity of 3240fps. Having said that, velocity is not the be all end all determining factor in how good a certain load is. I will add this, I don't mind pushing a load a little hotter in a bolt rifle, but won't do it in a semi-auto.
