Spanky, congrats on the new baby. I can't help you any on loads for it. I had a 6mm Rem Model 7 years ago and hated it. It's long gone and I own nothing around 6mm. Excuse me for saying this, but to me they're bastards....they are not a varmint rifle and they're not a big game rifle. Yeah, yeah, a hundred guys will jump on here and tell me how many deer or coyotes they've killed with the .243. I've killed as many with a .22lr or a .45-70...so what? I guess they might be sweet on antelope or similar, but we're short of them here. I just have no need for one, my pistol caliber carbines, the .45-70 and the .223 and .22-250 will handle anything I need....that isn't mentioning the larger necked calibers, 7mm-08, 308, '06, .30-30, 7.62, etc. I don't deal in hides, so whatever kills effectively in a particular situation gets used, if it is Handi.
Pete
