sheesh, put even a 28" barrel on a 223, and it will get the 90 and 100 gr bullets to 2800 fps, and they have the SAME BC as the match .50 bullets. THAT'S why they are able to do well at 1000 yd matches, even at a "mere" 2600 fps muzzle velocity.
1. My Barrett has a 29 inch barrel and gets 2900 fps with match ammo.
2. The BC for the 750 grain AMAX bullet is around 1.01 (pretty much the highest BC of any small arm projectile out there)
3. My McMillan with the 36 inch barrel gets 2950 with match ammo (different powder load.
4. There is no way in hell that ANY .223 projectile will ever have as high a BC as a .50 match projectile.
5. You don't know anything about .50 caliber rifles or shooting as shown by the post you put above.
This is the quote of the year for you...
"...put even a 28" barrel on a 223, and it will get the 90 and 100 gr bullets to 2800 fps, and they have the SAME BC as the match .50 bullets."
Screw that...I carry a pair of snubnosed S&W .500 loaded with custom splitnose, blended metal bullets. They do 50000 fps and fragment while flying down range, due to air friction, so they impact like little shotgun shells.
Just last week I was out shooting homeless people [for the meat, of course], kidnapping underaged girls and dragging them back to my combat winnebago and I've actually replaced my CAR15 with a can with this brace of snubnosed S&W .500.
Of course, I still keep my CAR15 with a can close at hand, but for day to day carry around the aslyum, the .500 Smiths are the shiznit.
