I loaded up some 41 mag using 10.0 hrs of unique powder with a Winchester large pistol primer and 210 gr truncated fmj bullets does that sound too hot?

All the reloading manuals are different.

Nope!Actually,I think you'll find it right nice.Not a real magnum load but with just enough bark to let you know your projectile is on its way.

I like 8.5 grains Unique for JSP/JHP. I think your load is near (not over) max for Unique and jacketed bullets.

Just check with Alliant powder co . for load data using Unique in the 41 magnum . Regards Paul

You are easily approaching MAX with that load

10 grains of unique is going to get you 1200+/- FPS depending on barrel length

I use 7 or 8 grains of Unique with a 210 grain cast lead SCW in my Model 58.

If I want a more powerful load than that I go to 2400 powder.

I generally don't shoot jacketed handgun bullets, so I can't comment on that.

Alliant lists 9.7 grs of Unique as max using a 210 gr bullet so you are just slightly over the listed max . I would choose a different powder for more power . HS-6 / 2400 / Enforcer all will give you what you want at less pressure . Just my thoughts , Regards Paul

If that is the Hornady bullet, use their data! If you don't have their manual, call their customer service number, 1-800-338-3220. they have always helped me with the loading data questions, even strange ones!
