Stock they are great...but ive since opened up chambers to be .003 over groove diameter of .372 (chambers came stock .365-.367 and are now all .375) and have a wire spring set up internally. Now my guns are very accurate and i get no gas cutting etc
Seems kind of goofy that they would bore the chambers under-size. Perhaps they are trying to reduce pressures in case the shooter manages to load up with a hard cast bullet and a maximum load of Triple 7 (or something like that).
