I get the idea, but the problem is the radiused ogive will do the same ironing and spreading ahead of the ring picking lead up, so I would expect the pressure issue to be the same on the first shot even if the end cleaning result is better. It would be interesting to run a pressure gauge on a barrel while doing this. I've also wondered before if one took a semi-jacketed bullet and cut it off and chamfered it at the leading edge of the jacket if that wouldn't scrape the lead off pretty well. But I'd be firing it at low pressure, just to be sure.
