SU-I totally concur with you about the HPBT Sierra. I have used it a lot in several cals and have always found it to be as tough as a cup n core bullet around. Plus it's always shined well in the accuracy dept as well.
I do kind of wish that it's BC was a bit better but I have used it more than a fair bit for chucks out to 500 so I guess it'll do just fine...
By the way, I'll give you a call tomorrow to wish you a happy bd...grins
