I dont think anyone is stating it's impossible to get good groups using the 245 or 295 Powerbelts. What reviewers like chuckhawks.comare trying to demonstrate is thelack of consistent accuracy using the lighter bullets in a majority of CVAs like yours.
I think the important message here is that it's easier to get good groups using the heavier ones. The reason the 405 Powerbelts were not included (even though they fared real well at the range) is because CVA/BPI does not allow any conical over 400 grains with 100+ grain loads. Otherwise, the 405s would be included in the same group as the 348s.
There was a time when cva.com allowed the use of the 405 gr. Powerbelts with a maximum load of 85gr. blackpowder equivalent. Im not sure what CVA/BPI's stance is on this today. You can email them at...
