Thread: Economical Gong Gun cartridge?

I recently built a 6mm CM to take over from the 308 to reduce recoil so I could better see splash, but its not shooting worth a damm so its back to the trusty old Lithgow 308.

All this got me thinking, pouring 46 gns of powder for the 308 and 42 for the 6m CM behind a projectiles at a $1+ a pop isn't viable for me. The 6mm CM being hard on barrels just compounds the issue. Some matches are approaching 160 rounds - a hell of a lot of rounds and even more $$

The 6x45 thread has a lot of very interesting data on the "wee" 6mm's

I wonder what a 6mm/204, 6mm ARC or 6x45 AI with a 95 gn projectile and 27 gns or so of powder will loose to the the bigger boys. By way of comparison, the 308 ammo I've just loaded is a 165gn G1 BC .47 at 2780fps Any of the wee 6mm's will give about the same velocity for 95 gn projectiles of a similar or better BC - and way cheaper to shoot. The 6x45 AI really shines in value with its use of 223 brass (I have 500 Lapua cases !!)

just remember copper wire was invented by 2 scotsmen fighting over a penny
