Has anyone here built one? Thoughts?
My use would be shooting steel to 500 yards. But sometimes in a match the steel has to react (spin) and .223s struggle. I figure a 103grain at 2600 will make a huge difference over a 75 at 2400. My restrictions would be a small frame lower, factory ammo, with a muzzle velocity less than 3K.
Such a short barrel to be going that slow with a 75 in 223? 20 inch tubes should be able to hit 2750 really easy... and that should make a difference. You may be well under even 16 though.
