Thread: Testing a conventional approach to load development

Let’s assume, when you say modern bottleneck cartridges, we’re covering rifles from the last fifty years or so. Do we ignore chamber differences and assume, even if we load to max, that nothing untoward is going to happen? No real damage and maybe the worst that’s going to happen is a stuck bolt or just some brass issues? Is this acceptable now?

Ignore this, can’t seem to edit. GPM raised the 260 load data issue and you’re gone part way to explaining your thinking. The chamber differences still bug me but if they’re still within tolerances can we assume we’re still ok? I ask this as I was getting bolt lift issues at the bottom end of powder charge when loading for my 270. It was my first handload so I was being conservative but it stuck with me, hence the questions.
