Thanks for all the replies, I appreciate the info! I know the Hi-tek coated 230 grain TC bullets shoot extremely accurate through that H&K 45 CT.

The problem I have with my HK VP9 is not the rifling. There is no throat. The sharp edges of the rifling 'shave' off a bit of the bullet and makes for poor accuracy. Jacketed works well. I suspect if it was properly throated it would shoot cast very well.
Unfortunately HK also 'nitrides' the barrel so using a throating reamer is 'difficult'.
Maybe they put a decent throat on the .45 barrels?
Don't know. From what I have read from others the VP9 might do ok with lubed cast bullets. I PC all of my pistol bullets and I suspect the sharp edge to the rifling is scraping the coating.
Every now and then someone reports a buildup of lead at the mouth of the chamber. Others with similar barrels don't report problems. From what I have seen lately many mfgs are not throating their semi-auto barrels.
I am guessing you mean the Walther. I have no direct experience with the PDP, but I have owned a PPQ for about 6 or 7 years. I am guessing the barrels are very similar. I have never experienced any lead build up problems with it. When shooting it I generally run from 50 to 150 rounds through it.
A vote for anyone other then the conservative candidates is a vote for the liberal candidates.
The PDP & PPQ have the same Polygonal rifling.
Just to clarify, the poly rifling is not the problem, it is the lack of throat. Some get them to shoot ok. I have not.
