I agree that 1:10 would be best, and SEI does offer a 1:10 16.25" barrel.

Not that it makes a big difference, but the SOCOM M1A has a 1:11 twist.

190's want hurt the rifle, the damage comes from gas pressure and gas volume. If loaded to max or above as some do to push a 190 out to 1000 yards you have to be aware of the effect ambient temperature has on chamber pressures. A max load at 70 degree's is going to be an over pressure load in August at River Bend when the temp reaches 90+. There is less powder in a normal 190 load than a 168 or 175 for gas volume usually is not the issue. In fact you usually run out of case capacity with heavy bullets in 308/7.62 cases and can't get enough speed to take advantage of the high BC on heavier bullets. The old wives tells of heavy bullets is BS, the bullet weight has nothing to do with weapons damage, it's the powder selection and charge weights that are the problem with heavy bullets in 308 cases. You can blow any firearm up with poor selection of powder and charge weight even shooting 110 carbine bullets. As for performance the 190 is going to be a poor selection if the barrel has standard twist rate that is selected for 147/150 bullets. The 190 most likely will tumble long before it reaches any target beyond 600 yards. Not enough rotational energy to keep the butt heavy beast pointed down range and as there is more energy in the ****** of bullet because of mass it most likely will yaw and flip in flight.

Question Why?

Why a 190 grain bullet? You mean to tell me he can't get the job done with something a bit lighter and much less taxing on his gear ?

As for the 190s, he can shoot all he wants - at his own risk if he closes the gas valve.

H2O:

Not the OP of the comment but I have a question:

So on all three of the rifles, the gas system is located the same distance from the chamber or not?


So on the standard, scout and socom the gas system is located the same distance from the chamber, it's just the barrel length after that that is cut down? or no?

The gas port on the barrel is same distance from the receiver on all barrel lengths.
