Just wondering if there is a difference besides grain weight. personal preference or hardness of metal.

The 190's are slightly harder, and have a slightly greater cutting diameter.  That's it.

The hardness of the 160's today is about what the 190's were a couple years ago, they've all been boosted slightly.

The 190's make a great visual impression!  What a warhead.

Figured you would know Sir!

Thnkin of using that warbird - for a BHead this year.

Thank you,
