I'm trying to decide between two Sako rifles, both in 375 H&H. One is a factory TGR-S (995) with a factory synthetic stock, 20 inch barrel and express sights. The other is an AV with a Jim Borden custom fiberglass stock and a NECG ramp front sight. I have heard that the TGR-S shoots loose from the factory stock under recoil because of a small recoil lug. (but you hear all sorts of things)

What can folks tell me about these two action types? How are they different? Is one better for some thing than the other?
