After a 25 year hiatus d/t eye problems, I am again venturing into the Thompson Center Contender series of cartridges. What triggered my return was the location of a long sought after barrel in the 257 TCU caliber. While there seems to be quite a bit of information on the 6, 6.5, 7, 7:30 Waters and a few other TCU cartridges, there is very little on the 257. Which is interesting since the few posts that refer to it speak of it in glowing terms as far as accuracy is concerned. Since many of you have served as mentors in many other areas of LRH, I thought maybe, just maybe, someone might be able to assist me with some reloading data for this cartridge. I currently reload for some 25 to 30 cartridges including some wildcats such as the Gibbs and Ackleys so I'm not new to the game, but I'm always challenging myself to new ventures.
