Can anyone tell me why the 150gr. supreme elite bullet in the 270wsm is classified for cxp3 and the 160gr. supreme elite bullet in the 7mm wsm is not classified for cxp3?

Welcome to the Forum.

Not sure who makes the bullets you mentioned. I would contact the manufacturer and pose the same question. Take care...

One can only surmise that either the bullet construction is not up to heavy game standards at the velocity it is driven, or it has not yet been tested/rated.

Welcome to the group! I hope you will spend some time with us discussing issues like this one.

I assume from your screen name that you are a shotgunner. While I do not currently own any, I do like a Franchi shotgun. I am not a shotgunner, so I have one utility shotgun I use for all purposes, but I have shot Franchis and they are really nice guns.

FranchiGuy,

Welcome to the side

Firstly your talking about Winchester ammunition I think. CXP ratings are used by them for years.

Could be that they market polymer tipped bullets with the Supreme Elite name but internally they may be different. Not sure though.

Looking at Winchester's website it appears that the difference is bullet construction. Bullets, and guns, are like golf clubs. You have to pick the right one for the particular set of circumstances you're facing.
