I have a drilling by Muchler, circa 1928-30, chambered for 8x57JR. (I've already slugged the barrel and checked the chamber). I'm seeking reloading data for this round.
I understand that GGCA is reluctant to give reloading guidance - understandably; however, can anyone point me to a source of reliable data? I have found a plethora of data for the 8x57JS or JRS, but other than some vague suggestions nothing for J or JR.
I have found .318 bullets in 170, 196 and 200 grains. All I need to get started are some reliable powder recipes. The only powder company that replied to my request for data was Alliant, but the data they gave me all had higher velocities than I am comfortable shooting in my gun (2300fps). As I understand, 1800fps was typical for the 8x57JR pushing a 196gr bullet.
My drilling is in excellent condition, tight on face and with excellet bores.
If anyone can assist me with some published data for the 8x57JR, I would be most grateful.
