I have a "new" (to me) 375 ultra mag. Unfortunately all bullet makers feels like giving me very blunt nosed projectiles. Has anyone ever used Lehigh bullets. A search didn't pull up anything on the forums. they have a 330 grain solid that is stated bc of .9 but the length is 2 inches. Probably too long for my twist. According to greenhill it is, but I've also read that as your fps go up you can change the 150 constant in greenhill. Which of course would help me out. Just hate to spend 65 bucks for 50 bullets for nothing.
I emailed lehigh and they wrote back very quickly with a response that the bullets were for a 12 twist. Which lines up perfect for 375 RUM. Is there any documented evidence that brass will wear out a barrel a LOT quicker. There seems to be a lot of bmg guys using solids. I just haven't seen/read where brass vastly deteriorates the barrel. I'm not saying it isn't going to wear out faster. But, we are talking about doubling our BC here.

Reason: my grammar is horrible
So, am I right in thinking that the problem with mono metal bullets like Lost River is that accuracy is sensitive to bore diameter? Do you think having the grooves helps? How do you think the Nosler E-tip will fare without grooves as to accuracy? Nosler usually gets the accuracy right on their bullets.
Barnes TSX with grooves seem accurate for most people. As I remember GS Custom have small rings on their bullets. Haven't heard accuracy gripes with GS.
