I must have misunderstood the question. I thought the first post was asking specifically for PD loads, not deer loads. Are you recommending using deer loads for PD's? I have shot a fair number of PD's with "deer loads" mostly to use up odd lots of ammo or bullets. However, I was never very satisfied with the results. I much prefer shooting PD sized critters with 70-80 gr bullets in the 6mm Rem. Much better 'splat' factor. The 85 gr HPBT also works well.
As for powder selection slow powders like 4831 work very well with the heavier bullets used in deer loads, but give up too much velocity with the lighter bullets I prefer. Hodgdon data shows 4831 to be over 220 fps SLOWER than H380 with 70 gr bullets, for example. Also in my rifles accuracy with 4831 has been ok with the lighter bullets, but not quite as good as some of the slightly faster powders. Vic
