bigcountry,
I gotcha covered...
I shoot 150gr (3pyro pellets) and a 220gr "Dead center" bullet made by Precision Rifle Bullet found here
This load can easily print M.O.A. groups or I would stop using it. Now recently, I was impressed by the Shockwave (Hornady) 200gr bullet and may buy some of them to evaluate.

Last year, I had an opportunity to take 3 deer with this load and it was complete and terminal upset...instantly! The year before that, 2 smallish does were milling around about 35yds from my stand for about 30-45 minutes. I had told myself either I get them both or they both walk. Wouldn't you know they lined right up at about 25-30yds and with one pull of the trigger they both piled up. Complete pass through on both and both instantly dead.
I like having the extra power that 150gr can offer and my accuracy isn't suffering. I employ the same logic as the guy that won't deer hunt with the 30-30..."but what if the one walks out at 200yds and all you have is a 30-30?"
..."well what if the one walks out and all you have is 90gr and a 350gr conical?"[][:@]
