I appreciate all the advice here. I think I lucked into a pretty accurate rifle for the kiddies, as it shot everything pretty well.
55gr Ballistic Tip - 48grs Big Game
70gr Sierra Blitz King - 41gr Varget
95gr Ballistic Tip - 44gr VV N560
The 20" barrel is fairly stout, I'm sure it helps out quite a bit. These loads all show a lot of promise, especially the 95gr NBT. I'm fairly amazed at what the cheapest M700 made can do, right out of the box...well, with a slight trigger tweak.
