Welcome back to hunting Norb! I use a 2004 CVA Optima Pro 209, not as nice as their new lineup, but super accurate gun. As far as your load selection, Triple 7 is good, I used it for 7 yrs before switching to Blackhorn 209. If you are a loose powder guy, I would highly recommend this stuff, it pours great, shoots accurate, cleans up nice and you can shoot 20 or more rounds without swabbing. I also picked up about 200fps more with the same 100gr charge. If you go with it you will need to use either Federal 209A or CCI 209M primers, with the 777 you will need either Winchester 777 or Remington Kleanbore primers. Don't overlook primers, they will turn a sloppy erratic group into a sub MOA group. As far as Powerbelts go, see how your gun shoots them then go kill something with them so you can see if you like the terminal performance. Everybody likes something different. Good luck this hunting season!!!
