I beg to differ.
I shoot M95 Steyr and M91 Mosin with far less than perfect bores and both shoot just fine.
I have seen number of rifles with pitted and dark bores,frost,even parts of rifling rusted away yet still shooting on par with many modern rifles.
If you are looking for cast plinker you might be better off with K31.There are many more choices of bullet molds in this caliber than for 8x56R.
That's great, but my slightly frosted Chilean .308 is good for maybe 30 shots and then I'm pushing strings of lead from the bore.
I did buy a k31 recently, though. The dies were the hardest things to find. I found a set yesterday after a frustrating month.
