So I need to develop light 44spc loads for cowboy shooting. I plan to use 44m cases. I just read were a guy throws his charge then fills the case with corn meal to keep the powder in place for a better burn. This would help with my 38spc loads in 357 cases. Anything I should consider doing this? I read a while back where a guy filled precision rifle cases with a light fiber material for the same reason. That story said to weight the fiber and add it to the bullet weight then develop the load based on that weight.
