in my quest to find a accurate pellet in the sig Virtus, I have tried the following : Crossman premier HP 14.3 gr these are my go to pellet , and I find them to be fairly accurate and cheap to shoot. Predator polymag shorts 15.89 GR not as accurate as I was hoping for, several flyers ... Gammo redfire 15.4 GR these were accurate no flyers good grouping. I can't figure out why the gammo did better then the polymags other then the weight , they should have been closer in accuracy.? FX domed 15.9 GR The most accurate pellet in my pellet test . I was able to group them nicely and performed great. H&N field target green 9.57 GR I was surprised that these did not perform well at all. lots of flyers, and not accurate in the grouping. ?? so far first : fx dome 15.9 2nd crossman premier HP 14.3 GR 3rd gammo redfire 15.4 GR With the Crossman the cheapest, and with decent accuracy , they seem to be the best cost / accurate choice from the list.
