A HP has a limited working range and is dependent on softening the alloy, which makes the bullet less accurate.
Out to the practical hunting range of 200 yards, maybe 250 with some cartridges, I've not found softer, amlleable alloyed hunting bullets to be really less accurate. I've also found the HP to enhance expansion across that range. The choice of which to use just really depends on the equiment available to the castor. I can HP any bullet with the Forster tool and can also double alloy with the moulds I have. Either way produces very good expanding hunting bullets. The 2 alloyed bullet is a good option with both working equally well. No real need to denegrate one to justify the other.
