Cramer #B1,2, and 3 . B4 is 7mm .
27-130 and FP , my FP casts .279 @ 142 gr .
279-124 NOE , mine casts .279-129 gr .
280473 GM Lyman . Pope design . Mine casts just barely scuffed in my .280 sizer so probably about .2799 and 124 gr with a long tapered GC shank . This one has lots of room to move metal into grooves and the GC shank gap . It's probably the best bet for this down size .
NOE offers at least one fat 6.5 in the 270-140 .
