I don't know about the hollow point rounds. My fiancee's dad has loaded some for her and him for the past couple years (243 for her...257 wby mag for him) and I they've been s**t. The first time I thought maybe it was just her shooting, but after 2 or 3 lost deer I find it hard to believe that it's them that many times. Since it's not really my place right now (he reloads) I haven't said anything, but come next year after we get married, I'm gonna fix her up w/ some corelocs or power points that I know work.
