So the specific rifle I'm intending on trying this on is the kral 20" barrel for PB's. I don't know what the twist rate of the barrel is yet but after watching all of Matt Dubbers AB101 videos a few times, I'm pretty sure the barrel is most likely too fast a twist rate for optimal long range stability using high velocity pellets/slugs. I'm currently pushing 28gr .22cal slugs at 920fps and have room to go further if needed but I'm thinking that if I want these and other slugs and even the RD Monsters to perform well out at 100+ that maybe reducing the initial drag and possibly overall spin would help.
I purchased a spare PB barrel and am planning to essentially sand/polish down the landings of the grooves for the first 50-65+% of the barrel then polish a graduation for the next 10% and leave the factory grooves/landing/choke.
Needless to say I plan on doing this with great trepidation and would welcome a scorning from any of the many seasoned tuners here...
