[QUOTE="Pdvdh, post: 384860, member: 4191"] I don't want to add so much water that the water ends up being squeezed out forward of the case neck, thereby fouling the bore. I absolutely agree that a water-wetted bore downstream of the bullet and case neck will increase case pressures. I absolutely disagree that placing a thiin film of soapy water solution between the cartridge and the chamber walls will increase pressure. The reason I'm going to use a soapy solution is because the soapy water is slippier than non-detergent water, and the soap will break the surface tension of the water and allow for a well-wetted thin film of water over the entire case surface, rather than a bead of water here & there, as appears on a freshly waxed auto finish. The reason I'll only fire one shot, is based on 4+ years of college engineering education, 30 years of engineering practice, 35 plus years of shooting and reloading experiences, and avid research and education related to reloading, hunting and shooting; I [B]know[/B] that the pressure will not be increased, and that case head flow into plunger holes or ejector slots in the bolt face will not be increased by the lubricity of water between the cartridge case and the chamber walls. Call me cocky of you choose. I have no doubts. Place water or any other liquid in the bore and pressures will increase. BuffuloBob stated that he was grasping at straws trying to identify a plausible explanation for increased pressures because clhman stated that factory rounds were jamming up in the .22-250 - which would imply a possible common source of elevated pressure for both the reloads and the factory ammo. Like I said, I have no explanation for elevated pressures from the factory loaded ammo. Any bore fouling or blockage should have been removed with the first shot fired in that .22-250. If the following shots were also sticking, I'd pull the bullets and conclude the factory loaded ammo either wasn't factory loaded ammo, or that the factory loaded ammo was defective for some unidentifiable reason. BuffaloBob never said he had high confidence, or any personal experiences to believe, in his hypothosis. I'm seating bullets now... :) [/QUOTE]
