The 47 has few cons, but according to many, it must be pushed hard to match or come close to 260 performance w/heavier bullets.
It's obvious the 47 needs higher pressures to match 260 MV and I would think this would negate any edge it may have in longer throat/barrel life.
I have to ask, is there a potential problem with ignition in cold weather using a small rifle primer with the 47?
I would think for a hunting rifle I would avoid it.
In my 6.5-284 I can attain 260 Imp speeds with lower pressure by going to a slower but accurate powder, according to QL.
AND, I don't have to buy expensive 260 imp dies and fire-form.
