There is only one 450 Nitro Express. There is a #2 and it's called 450 #2 Nitro Express.A 3 1/4" case similar to the 45-120.
The way I see it it's a low case pressure 458 Winny. It'll toss a 480 to 500 grn slug out at 2100 to 2200 fps.
"When you see that in order to produce, you need to obtain permission from men who produce nothing; when you see that money is flowing to those who deal not in goods, but in favors; you may know that your society is doomed." Ayn Rand
