All CVA Break-Action In-Lines are capable of handling a "magnum"
powder charge of up to 150-grains when using pelletized powder (typically
charges of loose powder exceeding 110 grains by volume will not fully burn
in the barrel). Such "magnum" loads should never be fired in other CVA In-
Lines that do not feature the one-piece Monoblock barrel design.
From a cva owners manual.....
Also does not list BH209 as a safe propellant for cva barrels....and states the max load for looase powder in 100gr. and only 150gr. loads in pellet form.....
