Looks like Kodiak Match is the winner by a narrow margin.By the velocity numbers, I bet they have a more consistent weight, which leads to the more consistent velocity and more consistent groups.It's also worth noting that the Crosman pellets were CPL and not CPHP from Walmart.
Any chance of building up a gas piston conversion on a Winchester Winchester 1029? I like the stock and fluted barrel on this model better than the 1000XS. It seems like the gains on a converted 1029 would be greater than those of the converted 1000XS.
