   It could be not enough shots to find the true centre. Hornady (podcast ep. 50) did some testing and found five shot groups averaged +/-0.3" away from the true centre at 100yd. A chronograph will let...

   I've found 2213sc to be more accurate than 2209. 140gr eld-m at 2713fps in a 23" barrel with 2213sc.

   It’s measured from the bolt face (when closed) to the crown.

   For maximum “modern bolt action pressure” I would use the CIP or SAAMI spec as bolt thrust is related to the taper of the case.

   Interesting idea. Another approach would be one meal a day, and then eat when you have to haul something out. Food is also good for when you need body heat. This is all at your own discretion though.

    I think your mate has some issues you’ll need to sort out first. With some very rough numbers from GRT you should expect about ~2900fps with a 24” barrel, 2213sc, and the 143gr.

    If you mean muzzle velocity, then yes. If you’re talking about bullet speed during flight then SG increases as velocity drops because velocity decays faster than rpm.
