I have been shooting the 290gr Barnes expander and they work very well in the Savage. The groups are acceptable for distances they are effective. I shoot the 250gr Hornady SST's exclusively in the black powder guns and have been pleased with them. The Barnes are better in my opinion when it comes to dropping deer. The Expanders mushroom as advertised and a blind man could follow the blood trail. I am going to try the Barnes original and the TEZ first. My understanding is that the TEZ is an Expander with a plastic tip to improve the BC. If they fly good there is no doubting about how they preform once they get there. I am looking to extend my effective range as I live/hunt in wide open country. If I was satisfied with a 100-200 yard load I wouldn't be inclined to move away from the Barnes Expanders as they flat out work. I have assembled some of the more exotic bullets from, Parker, Harvester and Dead Center and it will be fun to see how it goes. For now my go to load in the Savage is the Winchester 209, 44grs. of 5744 and the 2909 Barnes Expander. So far my Savage has preferred the heavier bullets over the 250's. My other guns all like the 250's best and I have found that the SST's work well across the board in a variety of guns. Which makes sense given the difference in twist rates from the Savage to then others. I have only taken 3 deer with the Barnes, which is far fewer than I have with the SST's but what I have seen so far is that the Barnes are significantly better at sealing the deal.
