All:

I have a question. I was able to pick up some woodleigh bullets for .577 at a considerable discount, but I have a question.

Some of the bullets are the full .577 NE, .585 diameter bullets - 750 grain soft nose.

The other bullets listed on the Woodleigh box says this:

Calibre: 577 BP
Diameter: .585
Weight: 650 Gr
Type: Weldcore SN
Quantity: 25

My question is this: Can these be shot in a full .577 Nitro Express rifle? Or, does the 577 BP listed on the box indicate it is only for black powder rifles?

Any insights you can provide would be greatly appreciate.
