BTW SuperCub that PRVI brass is terrific for reloading so hold onto it.
Thanks .... That's good to know as I just bought 200pcs of that brass as well as have some other 1F fed and WW brand here that I can beat up for load testing.
I'm having a 7x57 made up on a left hand Zastava and had it throated for 175s. Plan to make a load for the 160 NP.
That will be a nice rifle in LH. Unless you already have them on hand, I'd see if I could find some of those 175s. The RNs are not made anymore and scarce. A shorter throat may be a better route in case you have to go with a shorter bullet. I got a match chamber reamer for mine for that same reason.
More pics if you got 'em!
I will get more pics when I get it in hand. Those were from the builder.
