[QUOTE="davewilson, post: 93025, member: 4491"] 50, my personal opinion is that powder being forced through the throuat has very little to do with throat erosion.and ball powder being significantly less than extruded is also a very small factor. most of the throat wear happens while the bullet is getting started,the pressure builds up to 50 or 65k to get the bullet started and while this is happening the pressure is leaking out around the bullet acting like a cutting torch on the throat until the bullet moves far enough to seal the pressure. by now the powder chunks are all at least half burnt and there are no sharp corners or coefficent of friction other than the extruded would be bigger.i'm not so sure the powder isn't completely burnt by the time the bullet has only moved a few inches.
