I've got a bunch of 168 gr bullets I'm not using for anything else so I'd like to find a way to use them with the 300 whisper Randall made for me. The only book I have that includes the whisper doesn't show the 168 any slower than 1400fps. I like the 240's but they are not easy to find (and expensive) when you don't plan ahead and run out just when your suppressor paperwork comes through!
I know someone will ask so...
AAC Cyclone, sent the papers in april, I'm going to pick it up tonight.
