I just arrived back from Wyoming on my Deer hunt and wanted to let everyone know my experience with Barnes TSX Bullets. I shot my deer with my remy Mountain rifle in 270 win loaded with a stout amount of 4350 and 140 gr TSX. I shot him at 171 yards through both lungs and he took off like he wasnt even hit. He ran 100 yards before falling over but flopped around and didnt die for a long time. When I gutted him out the hole in each of the lungs was a size of a pencel. I found the bullet in the off side and the bullet had no expansion what so ever. I couldnt beleive it. So to say that I will not ever use Barnes bullets again is an understatement. Avoid them like the plague. I am very dissapointed and am actually sending the bullet to barnes with a similar article. I will put of pics of the bullet once I have more time.
