Looking for info on 38-55 loads using a 260gr fngc with either H4227 and/or Unique.
Rifle is a re-bored 336 approx 20" barrell.
Looks like folks are using around 17gr of H4227, any experience with this? Measured or even estimated velocities?
Only info I've seen with Unique is a 10gr load imagine its a powder puff.
Tried a search sure its been covered before, no other powders or boolits on hand.
Thanks, Matt.
