This season I want to finally use the .303 99 Carbine but most importantly a 50/70 Springfield in unbelievable condition and is a family heirloom. To my knowledge, no one in our family has fired it but is quite tight and mirror bore.

Does anyone know where I can buy low pressure black powder loads for this? Buffalo Bore is out and they have to go on back order. I can't wait.

I'll gear up to reload if I have to but do not plan on shooting it much. I would rather buy 2 boxes of ammo and be done rather than gearing up for reloading.
