I'm in the process of working up a load for my 7x65R drilling, with a bit of help from various users of this calibre here and in Germany. The published load data isn't a huge help as it is all for bolt actioned rifles able to withstand higher pressures, rather than for an elderly breech-loading rifle.
Even though I'm being very cautious, it occurs to me that the pressure indicators I'm used to in bolt actions with cases spacing off the head will possibly be different to a rimmed cartridge spacing off the rim and essentially immobile in the chamber, therefore no flattened primers. Is there anything specific to rimmed cases that I should be looking for as I work up to near maximum loads for this kind of rifle?
Thanks,
Adam.
