If you end up going with lighter projectiles make sure they are sturdy enough for big animals. The Blitz and Vmax types aren't designed for big game. They will work on light animals but you will likely loose a few big animals with them. I religiously ran 100grain Hornady and always had a good run with them. Still run them in one rifle.
In another rifle I now use 87 grain Hornady spire points, and 85 grain Interbonds if there's a bit more at stake. These both shoot in the same group at a hundred yards.
The only projectiles I had a bad run with were Lapua Mega 90 grains. I had to give a number of stags a second shot with those. My mate I hunted with at the time commented on how deer that shouldn't have were getting up.
