Got this email back from CVA today. I emailed them wanting to know if you could use a 3 pellet load with conical bullets in the Optima "Or magnum rated cva muzzy"

With a conical lead bullet the pellets will not work you need a bullet
with
a gas check on the back of the bullet. With conical bullets you
should use loose powder ,100 grains is max. If you use the PowerBelt
bullet
you can use the heavy bullets and use the pellets , 150 grains.


Has anyone used pellets with all lead conicals?

I've only used loose with lead conicals but I have used pellets with powerbelts. I prefer the loose for both in most loads.
