I bought a box of T/C Prelubed 350gr Maxihunters today and shot 'em up the range in my new T/C Firestorm with 90gr FFG Goex. They shot well, but I'm a little concerned about their terminal performance and that they went down the barrel with very little resistance...Much less than a Powerbelt or other sabot. Is this normal? They also seemed to shoot better with a dirty barrel...possibly because there was a little more resistance? Anyhow, I couldn't pass them up...they were 5.00/box of 20.
