All kidding aside 7828 was developed for the 7 STW and my best load was with H 5010 (no
longer made) but H 50BMG is good and so is H 869 for heaver bullets and for 140class bullets
H 1000 and Retumbo are a little faster but start low with them and work up.
82grns H-1000 shooting 140 grn Accubonds and Bergers. Hits animals like a hammer of Thor. I shoot in deep south Texas so my loads may prove light to northern climates but it is not uncommon to shoot in 80 degree weather in February.
Has anyone tried Reloader 25? I was using H870 (no longer available) and AA 8700 ( no longer available) and had developed some very accurate and impressive loads for bullets up to 168 gr. Now I have to start all over again to find what combinations work well in my Rugr No.1. Any info would be appreciated. I would have a decent starting point. Can anyone furnish the pressure recommendations as well? The loading data tha I am finding is 53,000 psi maximum and velocities listed are in the range of my 7mm Remington Mag.
For some odd reason, my rifle didn't like any combination of bullets or weights with RL 22. I may try it again. H1000 and IMR 7828 were good performers with all bullet weights, just can't find any locally. My supplier has had an order in for over 3 months and has not received powder, primers, or powder. So I'm trying to work up loads with the powder that I have on hand for this season.
