Yes it will stabilize the light bullets fine. Try some 85 gr BT's or 75 V-Maxes for Varmit bombs.
For the heavy bullets I will also tell you the 120NP is great. We shot many Whitetails, Antelope & Mule Deer with this bullet from just a few yards to near 400 & we never recovered a bullet & the kills were dramatic!! The 115TSX does the same but drops more, the BC is not good. The 100TSX is neat too. With the 120NP, I was getting over 3,200 with RL25, with your 24" tube you should get 3,100 & change. Work up slow, RL25 kicks butt in that round & Retumbo looks promising.
