Hit the range today with my first reloads.  made them on a Lee Handpress (and quickly bought a Hornady press).

45 Colt, CCI magnum large pistol primers.  I made 10 rounds with 30gr of FFFg Pyrodex, and 7 rounds with 35 gr.

I initially got the black powder sub because I kept reading about using magnum with black powder, but it looks like I can use with smokeless as well, just drop the load weight. Is that correct?  Those were the only primers I could find locally.

Anyway, they were just proof of concept rounds and make sure I wasn't going to "shoot my eye out."

Cimarron SAA clone, and a Winchester 94AE.

I purposefully kept the load under 40 grains since the weak link is the pistol.  I have some Accurate #9 to make hotter/rifle loads, as well as #5 for pistol.  Have a line on Trailboss too.

Trail Boss and magnum primers should be ok, right?

I've seen a lot of people say they use magnum when they do not have regular primers.  They start at the bottom side of load and start from there as the magnum does add to charge vs a regular primer.  As always it is best to use what the data books/reloading manual says.  Hodgdon has reloading data on there site if you need some info on trailboss loads for 45LC.

Thanks for posting.

I also have a Cimmaron SAA. It's a frontier 5.5"  in .357.

Question, why did you decide to use a black powder alternative as oppossed to a modern smokless powder?

Cowboy replication?

Mostly because of the primers.  I actually bought 3 lbs of Accurate #5, but couldn't find LP primers, only magnum.

So I looked in to it, and saw that MLP primers are recommended for BP loads.  So I went and got Pyrodex (first BP substitute I could find).
