I'm surprised that EAA will only recommend the lowest power .45-70 loads. From data from Chuck Hawks web page, the .308 has a SAAMI mean maximum pressure of 52,000 cup. The 30.06 has a maximum of 50,000 cup and the .223 has a maximum pressure of 52,000 cup.
He also discusses the .45-70 and talks about 3 levels of loads. The first level is low pressure for old Sharps rifles and replicas and such and runs at 25,000 cup. The second level is for modern strong repeaters such as Marlins, etc and runs at 40,000 cup and the highest pressure reloads should be reserved for very strong guns such as the Ruger #1 or Dakota 10 single shots at 50,000 cup.
Now, if this Baikal double rifle is chambered in .308, 30.06, .223, .270, etc which all run around the 50,000 cup mark, surely it'll handle the hot .45-70 loads with safety. The only reason I can think of to suggest that it might be a problem is if the larger bore diameter weakened the action somehow, but I can't see how that could happen.
I'm picking it'd be safe for repeated full house "Hammer of Thor" type loads, but I'm sure as heck not sticking my hand up to be the one to shoot them first ...... a 500 grain bullet driven at 1800 fps is going to be extremely impressive at both ends in a 7.5 pound rifle!! Add a couple of pounds to the rifle and I'll think about it.
Still, the .470NE will drive a 500 gn bullet at around 2100 fps won't it?
That's some SERIOUS firepower!!
