Since trying out the 100gr TTSXs and finding how much my .257 likes them I have shot a few animals. I had been finding petals left behind in the wounds but the bulk of the bullet was missing and the game died quickly. I finally recovered one. My wife took a broadside shot on a Cow Elk which broke a rib on each side and the stump of the bullet was caught by the skin on the off side. I did not find the petals to know exactly where they came off but will find out when we butcher later this week. I suspect they shed on the way in because despite perfect shot placement the Elk moved off a short distance and bedded down. We waited 30 min then trailed it up. After slugging through near waist deep snow for 300yds we found it laying down and still alert 40 yards from where it was 1st hit. It got up and a high shoulder shot put her down for the count. Needless to say I am less than impressed with the TTSXs and will be switching back to my tried and true TSXs, which have never failed me and have held together even on heavy bone hits at close range. Has anyone had similar experiences? Maybe they just cant handle the velocity of the .257? I am a staunch Barnes supporter and this is the 1st problem I have ever had with them,I am quite disappointed to say the least.
