Canon,I'm much obliged to you for taking the time to explain just how to measure for expansion.I have a new box of Rem .338 ultra.I intend to shoot 10 rds. after filing the flat spots as you directed.We have state of the art measuring equipment at my workplace and I'll have them measured and use as a starting point.<P>I have an accurate load with 200 gr bal. tips that's going over 3400 fps using RL 22 with no problems ---- YET!! You can see this is not an academic exercise for me.I've noticed that engineers have a tendency to " fall in love " with a problem rather than solve it,so I appreciate straightforward advice on the " this is how I do it basis".<P>When strain gage data doesn't match expected results,it tends to get " weighted".Same with computer models.Thanks,again.
