Take a look at the top of the "powder slide" on your Star Reloader,, if it is stamped "2.8" followed by the
letters "B E" that means it will throw 2.8 grains of bullseye powder, that should answer Your question about
what type of powder to use.
I could find no reference to the type and wieght of the bullet that you mentioned in your post so can't give
any recomendations there, but a 148 grain lead wadcutter bullet with 2.8 grains of Bullseye powder should
put your load at about 750 feet per second, and with good accuracy and not much recoil.
as far as primers go, any brand name Small Pistol primers should do, I prefer Winchester brand , but everyone to thier own. good luck with your reloading ! REMEMBER, a double charge of powder may blow your gun up !!!!
