Kind of an old story but may give you a little more info:

The Nosler 125 BT is the king of Pistola bullets as manufacturers drop their pistol bullet lines.

All reports of those ACTUALLY using the BT make it the top of the line bullet to use, anyway.

Thanks for the help, I'll take a look at the ballistic tip. Love the gun-time to start barrel shopping
