The TC Contenders are a fantastic value for the money. Over the years I've had 41 different barrels for both the Contender & the Encore. Most of mine were Wildcats & most of them were made by Fred at Bullberry. When Fred & I hunted Africa he used a 17 caliber, a 6.5 caliber & a 7mm caliber. I used a 6.5/284 & a 338/284 both on the Encore frame. Between us we took a lot of plains game with no second shots being needed.
As mentioned the little 221 Fireball is one of the most efficient cartridges out there on the Contender frame, a little powder goes a long way!
