i just shot a ladder for my 6BR at 500yds. BAT SV, Krieger 1:8, Varget and 105 VLD target jammed .010. No surprise here, 29.8-30.0 was the sweet spot on both ladders I shot. On the first, 29.6-30 was under an inch 3 group. Second, 29.6 was out but 29.8-30.0 was still good. My question is, would you just start with seating depth tests at 29.9gr to give yourself .1 lee way on either side for a buffer (bad powder throws and the general innaccuracy of a chargemaster)? Just trying to get insight on reading ladders. Thanks.
