I have a 22" rechamber 358JDJ Contender and it's great, accurate with the right loads, kicks plenty hard but my dentist reinforced my fillings after I got it. Great round, easy to load for and lots of fun. SSK does good work and stands behind it. You won't go wrong with either of the two you related and I see T/C is now putting out the 375JDJ as a factory barrel, with loaded ammo from Hornady. I never thought I'd see that happen.
JD Jones could probably do that with all his round for the T/C, make loads of the royalties and concentrate on his other firearms works. He does great stuff.
