Ok so I have a 325 Keith mold and have a sweet load worked up with H110 around 1100fps or so but I'd like to try loading some down with universal.
Hodgedon's site has 6.6 grains starting load for a 300 grain cast.
Would I be safe to try starting at 5.5-6 grains of universal?
Also, at what pressure level does universal start to spike?
