RE: How much powder above max do you load with barnes TSX.
True Stubble, but Barnes has made it known pretty publicly you can probably go 2gr over book.
For instance, they recommend (hodgedon) recommends 80-83gr of H1000 for 200gr XFB. You start with Nosler recommended start with a 200gr Partition and your well over max already. See what I am saying?
I have been working with barnes for quite sometime and its a totally different deal.
But it seems to work for you.
