In a modern and high pressure action I think that the 6.5 X 55 is capable of much more than many manuals give it credit for.
I have a stable of Swedes', but am reluctant to load them much more than slightlyover the middle of the road recommendations. Course, they perform so well there is little reason to try to push it and risk injuring my brass or actions.
Does anybody out there have some real life experience handloading a 6.5 X 55 in a high pressure action? I'd really like to see it's top end practical limits.
