when using sabots and the modern powder how many shots can you get perfect before the sabot starts fouling the groves and tell me about the primer setup,is it enclosed ,if you got a good close up picture of one please post.One of the primer hole/breech plug area, also does the breech come out or is that sealed up.I know i need to hold one a shooting one would be even better to make a judgement call but i know no one in my area with one.
