43 Spanish Rolling Block Load Data

Slight compression, no need for grease cookies, wads or lubricated bullets... No yuck in your barrel, no need to wipe after shot, no stink, no black gunk on your hands... Great for muzzleloaders too.. Hope this helps.. Rick

They are the attraction of black powder..

Like the AA 5744 load. My most accurate was IMR 3031. I have used IMR 4198 with good results.
Sorry, but I will not give exact load data.
Want to try some Norma 200.

Regarding the statement about Trail Boss "I have heard that Trail Boss at same loads as for BP FFg works very good" I do not believe that is accurate. TB has large flakes meant to avoid double charging in old black powder cartridges. See the IMR website which shows only 12 & 14g charges for 45-70.
