I have one and it shoots great.
I need to go look at my load data but that is up north in the vault.
I do know I used 2 - 50 gr Pyro Pellets. A 209 primer.
Even shot well with 90 grains BH209 but dang if I can remember the sabot and bullet I used.
Mine is a tack driver. Way fun to shoot
cayugad has shot a Remington Genesis for yrs and can help you far greater than I can.
Hey Dave......
Bring on your ideas.
