Buckfever-
I'm all for Nosler Partitions, but I had some bad luck with one batch of them when I was testing several 6.5mm bullets in a 260 Remington (chambered in a T/C Encore with 24" barrel). The 140 grain Noslers were going out the muzzle at an average of 2712 fps (10' from the muzzle), and they did great in wet newsprint at close range. At longer range, over 200 yards, they didn't expand evenly, and they tumbled as a result. After tumbling, the rear cores would separate from the base, and some of them even made nice little mushrooms, but they didn't penetrate much farther. I couldn't afford to buy more bullets from a different lot, so this is a very limited sample.
It may have been this one batch, but it wouldn't hurt to check before you go hunting, at least if you expect longer range shots. My gut feeling is that the 140 grain Noslers belong in a 6.5-06, or one of the 6.5mm mags, for enough velocity to insure long range results. The 125 grain Partitions were great, as were 129 grain Hornady, and most all of the other bullets and factory loads I tested. Your T3, with handloads or some of the faster factory fodder, should be about the same velocity range as my old T/C. If your gun has a long throat that prefers long, heavy bullets, why not stick with the Hornady 140 grain SP for deer? The Hornady 160 grain RN also worked great out of my gun, displaying excellent, straight penetration, right through my chronograph. :cry:
