I am sure that either of these bullets will work equally well. I see no reason that nosler would put out a bullet inferior to the Partition and I would trust any product they put thier name on. Thats not blind loyalty, it is rather a reflection of the perfect expierence I have had with the Partition. I do load other bullets because I share the train of thought of some experts that claim the pemium bullets often fall shor of great performance on deer size game. For bigger or tougher critters I have complete faith in the Partition and the Barnes X bullets. The X bullets have performed great for me in the lighter weight per caliber on deer. For example I might use the 120 grain partition in 25 caliber but drop down to the 100 or even 90 grain bullet in The X for the same game. I always use at least one weight lighter with the Barnes X.
