I have not reloaded in 25 years. Back then I did 357 mag with Unique powder and 168 gr SWC.

Now I have a new lee single press, the anniversary kit. Is Unique still a good powder for 115 gr Hornady FMJ round? Is there a better powder? I will also be reloading 45 ACP later this year.

What is a good reload manual to get?
suggestions needed. (yes the unique will be new)

Edit to fix 155 gr to 115
