OK for the NAY SAYERS the action and barrel i have was assembled by the man NED ROBERTS himself and shows under the action next to the barrel lug an 80K psi proof ok engraved by i assume ned roberts himself or who ever did the test with the barrel on it ( no history prior to the gentleman i got it froms aquisition )
clearly i should in the name of gun information slap a no go gauge in it and see if the chamber and bolt are still servicable BUT ASSUMING that goes as planned
what are your thoughts of a load of 7828SSc in the BOB.. i have good luck with it in my 6mm remington under 103 ELDX
and with UNKNOWN COAL the 20 spent brass i got with the gun had the powder and load data ( NO LENGTH MEASURE) at 117 RN with 49 GR 4831 which based on book is about 4-5 grains over max... but book max is based on short action COAL not the mauser box potential...... SO,,,,,,, would you back off the given data and find the lands and use it or look at the 7828 to try to take some pressure off the action and use the 24" barrel length to the advantage
probably because he saw how down loaded that load data is.... heck in my hornady vol 10 thats load data equal to the 250-3000 savage.. my hornady book is down loaded BUT NOT THAT FAR .... if he was flinging 49 gr he already knew dont make notes lolI also inherited my grandfather's 44th Edition of the Lyman reloading handbook. He had notes on some of the pages, but not for the .257 Roberts.
