[QUOTE="sable tireur, post: 1193152, member: 27307"] 6mm Remington, No there isn't anything wrong with the 6mm Remington. Except that for long range shooting, trying to stuff the VLD bullets into that case and make it work through a short action magazine defeats any gains you might achieve. The bullets intrude deeply into the case compromising the powder space available. The 6mm Rem. case capacity is only a grain and a little more than the .243 Win. yet it's nearly 0.200" longer than that case. This doesn't bode well for using those longer, high BC bullets at all. Now, if you get away from the short actions, going instead to an intermediate length action such as the Defiance XM, you have exactly what Paul Mauser used when he design the 7mm Mauser cartridge for the M98 system, room to work with the longer bullets. Then, if you improve the body and change the shoulder angle to a modern design of 30 to 32 degrees, you really have a much higher performance cartridge. You find yourself getting about 61 gr. instead of 54.5 gr. and a much better range of powder selection for higher velocities and cooler burning, better barrel life. If none of this interests you then ignore the above and continue being happy with what you have. There is a ton of interesting cartridges out there and we can't all agree on which one is the best. The best is the one you are comfortable with and the one which accomplishes your goals. No argument there. Regards. [/QUOTE]
