So you're saying Thor 300s?I think you’re referring to the Hornady 340 gr Bore Driver ELDX? I’m not following your statements about inches.
But, I agree with @ElkArcher918, no, those are both soft cup/core bullets and would likely perform similarly on an elk.
I too prefer tougher mono bullets (or much heavier lead bullets) for elk.
Yes or very heavy (420-600 gr) lead.So you're saying Thor 300s?
