I really like what the 240 SMK can do (and would like to thank m21black for his advice waaaaay back on page 1). Since this thread started I have cut but barrel back to minimum legal and had some good short range shooting.

I have stopped for a while to have a 458 SOCOM installed on this action.

Has anybody made any progress with load development?

[QUOTE=Expatriot;18163]Have you ever had a subsonic bullet stop inside an animal?

If not then that bullet did not impart all of its "energy" inside the animal. Going to a heavier bullet is not going to increase the amount of energy imparted to the animal, all it will do is increase the amount of energy the bullet carries with it out the far side of the animal.


Have you actually ever shot an animal with the .300 whisper?

With your logic you should either to stick with paper clips or 12 gauge shotguns. Exit wound make better blood trails.

Resurrecting an old post to keep the information all on the one thread.

The 9.8 of SR4759 in a 16 inch barrel seems to do the trick. The old barrel was too long at 22 inches and cutting it back appears to have taken the variation out of the velocities for the 240s.

Happier again. Happier too that I am now using the RCBS Chargemaster to produce more consistent loads.
