Thanks for all the great advice, slowly I learn!

300 WSN, what is the WSN designation and the 358 WIN?
45 70 I have shot and liked it, do they come in multiple shot?
I don't have any feel for how a 7MM campares to a 300 win or a 270
What is the order of size /caliber cartridge size etc. of the above bullets?

Stopped at GI Joe's last and got to look over some ammo for the 300win and 45 70 the 300 win cartridge looked huge compared to a 30-06 or 270 cartridge.

I am leaning toward the 45 70. Are they a black powder substitute or modern powder? I have heard comflicting information. Awrite up on 45 70in general would help, plain and simple

Thanks again Phil
