I have a Black Mountain barrel in .308 on my Rem 40X very accurate even though the throat is well worn, Your P17 could have been a Full-bore rifle at one time and the barrel rechambered to 30/06AI
get the barrel slugged if it was a Full-bore rifle the bore & groove diameters could be tight and the twist 1:13" it will still handle 168 SMK's I have shot hundreds through mine with excellent accuracy,
case capacity is about 4% more for an AI case any factory equivalent load will fire form the cases, I haven't loaded a 30/06 AI but have had a 22/250AI they are quite easy to load for no drama at all
if you already have a 30/06 just use the load for that.
