Biscuits,
Many, many, many years ago, I started using Unique with my very first 357 Magnum loads. Over 30 years later, I still have that same canister of Unique. Yet, a million reloaders cant be wrong with the greatness of Unique, I just never found it to be that way!!! And so it goes
I shoot the RCBS 44-250-K bullet that weighs in at around 260 grains. Green Dot is my powder of choice. Seven to 8.0 grains of this powder gives right at the 1000 fps from my Ruger SRH in 9.5 barrel. Accuracy is great at 50 yards with the scoped SRH. I think Green Dot may be a sleeper when it comes to the 44 Magnum. You will get 1000 loads from the Green Dot as opposed to 700 with the Unique--just a thought.
If you have a canister of the Green Dot available, give it a try. Maybe a fellow reloader might have some for you to try before purchasing a pound of it. But then again, the Unique may work perfectly for you! Good-luck
