I’ve personally had a ttsx fail to open. It was a 100gr bullet fired from my 257 wby mag. Impact velocity would have been in the 3400fps range. It was a broadside shot on a whitetail buck. Entry was behind the front shoulder and I found the bullet in the far side shoulder. I know other people have great luck with them but I sure didn’t. The buck required tracking for about an hour with very little blood. I was lucky and we had fresh snow. I shoot accubonds in every other rifle I own and have never had a failure, so I’ll stick with them. It could very well have been a one-off experience but that was enough for me.
