How much bullet do you have left in the neck? I use the 512s for 6 Dasher and 6.5x47 Lapua (with 140s) with no problem.The Frankford Arsenal #512 boxes are great for 6BR's using light to medium weight bullets.
But the lid won't shut on the long 105's and such.
Not sure. I had some 105 Bergers loaded that did not fit. But i mostly shoot the 80 grain bullets, which fit fine.How much bullet do you have left in the neck? I use the 512s for 6 Dasher and 6.5x47 Lapua (with 140s) with no problem.
I have 5-6 of these boxes from Dave, he will drill the hole length to the size you request, each box has surpassed expectations, quality work. I also use the MTM RS-S-50 for most of BR and PPC variants.
