I'm just starting to load some light loads for my 41 and 44. Guns are M57 and M29 both 4 inch. I have Unique and Bullseye powder. My question is will large pistol primers be ok or should I still use the magnum primer. In some of my rifles I'll use a magnum primer vs lg rifle primer. I'm just not used to loading only say 6 grains of powder.
I have 215 grain cast SWC for the 41 and 245 cast SWC for the 44

Unique and Bullseye do not need magnum primers.

Ive also found with new Unique that Magnum Primers work way better. My gun/ brass is clean, accuracy is better. Just my observations. Im sure Magnum Primers are not necessary but Ive gotten way better results , with no pressure signs. Same with my .44 Mag

I've used 7.5 to 8.5 grains of Unique under an RCBS SWC cast bullet for over 40 years. I have tried other powders, but bang for the buck and 10 ring accuracy with excellent performance to 200 yards, a 210-220 grain cast bullet over the above powder charge is as good as it gets.
I might add that it's easy on the forcing cone and my Model 58 and Model 57 show no sign of gas cutting or forcing cone erosion. Other than holster wear they are virtually new guns after thousands of rounds downrange.

I like w231 for medium loads as well as Green Dot that is very close
to the same fps as w231 in all my revolver and pistol test, since
Green Dot is not always listed in loading manuals, but you can get
a "Guestament" on the amount of powder to use per the amount
of w231, at least with 38 spl. loads.

You don't check powder levels visually before bullet seating???? That's Reloading 101.
