I usually shoot 325 gr JHP for plinking.

Plinking. Heh.

Like a 325-grain bullet goes "plink"!

I "plink" with 325 gr JHP in the S&W 500 Magnum too. My new S&W 460 is still unfired. I will probably take some of my "puffball" .454 Casull rounds out to give it an initiation. The "puffballs" are 200 gr jacketed flat nose bullets with 37 gr of Win 296 powder. About 2000 fps at the muzzle of the Ruger .454 Casull. Quite a flame too. Easier on the wrist than the 300 gr Hornady at 1500 fps. Shooting a box of 20 of those Hornady rounds will leave you with a nervous quiver for an hour or two. Pretty physically punishing.
