I was hoping someone here can suggest some high B.C. bullets for 45 caliber rifle.

Barnes has a 500 grainer that they list as .412, and I have a few discontinued Barnes 450 gr. slugs that are near that mark. Availability from them is so so.

I know that 45 caliber is not considered a long range machine but again, if someone can suggest a few items I'd be grateful.

Have you looked at Cutting Edge Bullets web site. If they don't already make what you want they can make them.

Going there now.
Thank you.
