No problem. I plan on shooting 600 gr at maybe 2100-2150fps.

I am also interested in the 540 gr GS at 2250 to 2300 fps.
That's supposed to be an impressive whacker and the SD is around .300.

600gr at 2500fps--Nope, I am into being able to shoot a 2nd shot or more if needed. Also,I have no desire to have the gun become permanently imbedded in me as a foreign object!!
