What the bullet finally looks like matters not if it works reliably and consistently to get the penetration and damage needed.
I agree, one thing I should have noted with the RN was the wider path of destruction it left.
Did you shoot these for accuracy also ?
Yes, I did, and the 7mm 175 as always, has shot sub-moa in my rifles.
I will always over look Sierra for the reason that a 165 grain 30 caliber Sierra Game King out of an 06 was stopped by a white tail's shoulder.
I don't doubt you, and I don't doubt the stories like this from 'premium' bullets either.
I have a few stories myself.
