i really like reloader 7 for my pp 45/70 loads.cant find it anymore. is there any other smokeless powder that is available that is bulky and low pressure like reloader 7 i can use in my 45/70 loads? i do not want to leave a space between powder and the base of the bullet. i have used blackhorn 209 but it is too costly for a lot of 45/70 shooting. thanks before hand.
