reBAL,
I have fired three out of the four new rounds, 30-30, 35rem, 45-70. All but the 30-30 shoot really great in my guns. The 45-70 first time I fired it I shot a .875" group with my 1895 22" barrel. 35rem 1 1/2" group all at 100 yards the 30-30 my 336cs doesnt seem to care for it.
Once you get passed the plastic time which doesn't weigh anything you have a flat-nosed bullet with lots of umph. The 35rem kicks like a horse so I think they have it loaded pretty tight. I don't think I would worry about the 325gr bullet not killing any game it will do it.
I am taking it bear hunting next spring and deer hunting this fall, wish me luck.
