[QUOTE="Brent, post: 27086, member: 99"] [b]Re: Throat errosion concerning the large case 6.5\'s[/b] Steve, I'm so glad you responded to this post. I swear, I learn more from you in one or two posts than I learn all year on some things! [img]images/icons/smile.gif[/img] I appreciate your time sharing all this with me. Glad you didn't leave one sentance out either. [img]images/icons/smile.gif[/img] I'll let dad know about the 155's, that's interesting stuff. I agree with you on the PPC case design word for word. There are definately diminishing returns the longer the case is, that's about the only difference I can see.
