Way back when I first got into silhouette competitions (early 70's IIRC) I closely considered the XP100, but gadds it was just so ugly to me, so I chose a Thompson Center Contender instead and never looked back. I shot several different comps with that same Contender using different bbls/calibers. I did win a couple state (in class) and several local/regional matches with that Contender and still have it today. Ooops, not quite true. I forgot, I did trade the first Contender I owned for a 2nd gen somewhere along the line, but I do still have that one. I also hunted with it a good bit and took several deer and untold numbers of feral hogs over the years.
When my step-dad passed away a couple years ago I inherited his Contender that he used to shoot some of the matches with me. Since I already had mine, I shot dad's a few times then gave it to my 'yard' son. Hopefully one day he and I will go toe to toe with the two contenders at some old left over steel silhouetts, and maybe even a hog hunt or two.
