There you go...
I just got a new Z5 also.. for the heck of it last night I ran a .503 bullshop conical down it - it went down really well - so next I tried a .452 and several different sabots including a .458 sabot bullet combination- they all went down much harder than the conical - I was a little disappointed... but I had not cleaned the barrel yet -- so it still had new gun gunk in the bore... I cleaned it today but did not try any sabots yet...
