One thing to note; he was experiencing slight pressure signs using factory Hornady 140g ammo (very flat primers). He now reloads his own ammo at 2.775" length instead of the much longer factory stuff (I think he said the Hornady ammo came in at 2.82") and the pressure signs have dissapeared.
Wouldn't that increase the pressure ?

Re: 6.5mm Creedmoor ammo in UK
It depends, the longer overall length factory ammo may have been jammed into the lands which would increase the start pressure? Although I would have thought that the maximum pressure would cause flattened primers, not the start pressure.Mitch308 wrote:One thing to note; he was experiencing slight pressure signs using factory Hornady 140g ammo (very flat primers).
