So, I'm going to try one more time to get into LR shooting. I have an older rifle that I bought before I retired (back when I had money). I didn't have time to do anything then, bought it for when I retired. I retired, things went south for a while (wife had cancer, multiple surgeries, chem, radiation etc. now doing better) so I'm hoping to finally start on this before I'm too decrepit to carry a rifle. The (possible?) problem is I have a .375 CheyTac made when Lawton was in its heyday. It is an 8000 action, Lawton barrel and muzzle brake; the barrel is the 11.5 twist Lost River Bore. I am totally confused right now, after reading on the web most of the afternoon, about what bullets to use. I had a number of e-mails saved with this but I just discovered they are gone. So, my questions are: -- Can someone tell me, or point me to, the actual dimensions of a LRB barrel vs. standard bore? Maybe I could figure out the rest from that. -- Are drive band solids OK with this combo? What about standard lead core bullets? -- has anyone published (semi?) official load data for this round? I have seen some discussion on this but would like as much info as possible. Thanks in advance for any help.
