It is a thinner jacket bullet, so it will easily expand and fragment and limit penetration at the 308 Win speeds. But slow it down to blk out speeds, and you should get some good expansion and possibly some decent penetration. I'd use it. I'd use a 110 V-max on deer in the blk out, which is a varmint bullet and would be faster than the 125 TNT. The main issue with the slower blk out speeds is getting good expansion with the tougher bullets. So having a bullet that will expand easily is a good thing. Kill something this weekend, and report back to us!!
