In my experience, powerbelts tend to like lower charges of 777. Mine shoots a 5 inch group at 25 yards with 110 grains of 777, but drop it to 90 grains and the bullets touch at 25 yards. Every gun is different too. My brother shoots the same gun ( T/C Omega) and his shoots great at 110 grains. I just like loose powder better because it is cheaper and you can custom load for your gun. Personally, I would stick with the 295, get some loose powder and experiment. Load 85 grains, shoot 3 times, load 90 grains, shoot 3 times, 95 grains.............. See which is most accurate for your gun.

By the way, loose powder 777 is 15% stronger than pellets, so 85 grains is roughly equivalent to 100 grains of pyrodex or 777 pellets. You would have plenty of energy. My elk load is 90 grains 777 powder and a 348 grain powerbelt.

By the way, is your girlfriend ready to marry you or can I ask her out! You lucky dog.
