I am new to the 45-70 world. I've spent the last 45 years shooting nothing but flintlock rifles and as age and some infirmities are starting to set in I am looking for a new challenge. I need some loading help using 5744 powder. I have 2 bullets I am loading and would like some expert help determining load specifications for the 525 gr. round nose lead bullet. I cant seem to find any "official" published info on this round and don't want to over load or under load these. I've guessed a bit and am thinking a good place to start is around 21.5 gr. of 5744. Does that sound about right? any suggestions will help. I am shooting a Pedersoli Sharps 45-70 32" barrel, business rifle with Soule rear sight and front globe with inserts.
I fully understand the need to work loads up but as I have never used any smokeless powder before it's a new deal. I am using an RCBS turret press and have been measuring each powder load on a scale. I've only loaded black powder up to this point but would like to try some of the 5744 powder as most people I've spoken with say it's the closest thing to black powder when used correctly.
Any help will be very appreciated.
