Not sure if this helps or adds more mystery, BUT, we recently bought a Savage Predator Model 10 in 6.5 Creemoor for the wife, when loading 140g Sierra bullets, no problem with the recommended COAL, but when loading the Nosler 140g BTHP, if you go buy Noslers recommended COAL, the bullets are jambed pretty hard into the lands. Cant remember the specs off hand right now, but will get back with more info if you wish.
