highseas Posted August 23, 2008 Report Share Posted August 23, 2008 i would think it has something to do with less bullet drag and deformation their for giveing more acuracy in a caliber not known for great acuracy eather that or increased speed due to less drag hope this helps Quote Link to comment Share on other sites More sharing options...
Windknot Posted August 24, 2008 Report Share Posted August 24, 2008 Marlin made rifle barrels like this- might still do for all I know. Blurb was that it caused less bullet deformation and that it lowered peak pressure. Most user found that it worked OK with jacketed bullets, but that it fouled quickly with cast bullets, irrespective of the lube used.
