Just thought I'd let you know that I to bought a 209x45 barrel and was very disappointed with the accuracy on the first outing with the T/C 155 gr XTP sabot. The gun was consistently firing 4-6 inch groups at 50 yds. However, on the next outing I fired 195 gr Barnes Expander MZ sabots and this time was rewarded with three 3 shot groups hovering around an inch. I know this isn't the fix for every one, just wanted to let you know that some of the 209x45 barrels do shoot very well.
