For what it is worth,almost 40 years ago,I began loading 7 Rem mag,also.My local gunshop sold H4831 for $1.60 a lb.That was ww2 surplus 4831.I had good results loading 70 gr behind a 160 gr Sierra,and I think this was similar to a 1000 yd load in Sierra's book.I recall at 71.5 I got only 4 loadings before primer pockets loosened up. (DO NOT USE THESE LOADS<THEY ARE OBSOLETE AND DANGEROUS)I was 16 without a mentor,finding my own way.
That old 4831 is gone,and all the 4831 we buy today is different.That old loading data,and the old loading data in PO Ackley,is out of date and dangeous.The powder changed.A buddy brought me some swollen brass with the primers fallen out,a 30-06.What gives? It was his dad's sporterized Mauser,and his dad had an "old reliable" load of 4895,I think.A reloader buddy duplicated the old load with modern 4895 and it became dangerous.
Use new data,offline or keep your manuals current.
