I have a Hodgdon pamphlet from the 90s that showed around 50k cup with 58 gr at close to 3000 fps and their website now shows 51k cup/ 55.7/2800. Not sure what changed. Lou
Could be corporate lawyers desiring and advising clients to have a thick safety cushion when dealing with consumers.
In the mid 1970's I ran 58.0/H4831 with 150 partitions, 200 CCI primers in a 24" Sako L61.
Also 130 Speer Hotcor flat base with 60.0/H4831 both loads would put 5 shots in about 2 1/2" groups at 200 yards with a fixed 4x Leupy.
When we started getting what Hodgon labeled as "Newly Manufactured" H4831 my buddies and I ran the same loads and couldn't tell any difference. In regards to primers and cases, we would trim the .270 cases each time we reloaded, and the primer pockets were only beginning to flatten, like some factory loads. The cases were full as in a crushed fit, couldn't hear any powder from shaking.
