I'm looking to reload some new rounds for the 7mm rem mag. Could someone help me with some starting data for the 160 grain nosler accubonds or partitions. Thank you
I would start with H 4831 or H 4831 sc @ around 60 grains and work up.
Partitions will show pressure signs sooner than the Accubonds because of the extra bearing surface
so start with the Accubonds first and when signs of pressure show up reduce the charge by 2 grains
and try the partitions if you want to.
There are other good powders but the most accurate in my experance has been with the H 4831 sc.
With the 160 accubond I ended up at 71gr H1000, with federal brass, federal 215 primer, gave me aboput 3070 fps with a 26" barrel.
Work up to this load, my last tin of H1000 was about 1.5gr faster than the previous.
