Especially if you own an 8x57jr double rifle (.318" dia. bullet, as opposed to later .323" dia., designated "S" for spitzer bullet of larger dia. at 157 grains for improved ranging trajectory) rimmed mauser, and you found good regulation load, what bullet weight did you find most satisfactory? The early 8x57j and 8x57jr cartridges used a 227 grain bullet, but I think the German makers regulated the doubles, using the rimmed or flanged cartridges of course, for whatever bullet weight they thought most appropriate, from the heavy ones to the lighter ones of around 178 grains. Does anyone know, for a fact, that a particular bullet weight was most commonly used for these double rifles in this caliber?
