Since you bought the Omega scope from Natchez and you probably took advantage of their sale, you got the scope without the BDC reticle right? If that's the case, you'll need to aim high with the Nikoplex reticle at 200 yards, especially with only 100g of pellets. That's one of the main reasons I decided to go with loose powder. You have more room to play with the load and see what the rifle likes. You can't do that with pellets. It's either 100g (2 pellets) or 150g (3 pellets). With loose you can increase the charge in 5g volumetric measurements. Or you can weigh it if you like. It's really going to depend on you to get out there and test different loads and bullets/sabots to see what you need to do to hit black at 200 yards. Personally, I think a 12X12 target is plenty for 200 yards. If you can't at least hit somewhere on that target, you probably shouldn't attempt to take game from that distance.
