I have been using PSB as a filler with good results for a time now, but in the back of my mind, there is always a little concern about the itty bitty balls mixing with powder charges of large kernel powders. Yep..I use compression and maybe that takes care of the situation, but there is that little voice telling me some PSB might be in the powder, at least the top layer.
Soooo...Why not put in the powder charge through a long drop tube, seat a card wad over the powder and then the PSB high enough to give correct compression.
If there is no air between the wad and the bullet there should be no problems..right? Am I missing something here?
In the old Govt. carbine loads (55 grs of black) for the 45-70, they used a couple of "jute" wads to occupy the extra space created by the smaller powder charge and had no problems. They also tried, just shoving the bullet down farther as well.
I think I am on safe ground here, but want to check on the collective wisdom of the wise one, before I take the plunge.
