[QUOTE="tbrice23, post: 1069387, member: 59502"] My build has been completed for long enough to give an update on load development. The barrel is Douglass XX SS 26" magnum sporter contour on a Vanguard action and B&C stock. A little disappointed with Douglass because there are a few reamer marks in the chamber and I asked for a 1:9 but they sent a 1:10 twist so no surprisingly I'm having better luck with 140 vld than 150s. This barrel was pretty picky on what powder it likes. Imr 7828ssc is going to get more attention but it's usual diet is h4831sc. The target pics are at 200 yards but the groups look much more impressive at 100yards. Overall im getting 175 to 200 fps over my original factory 24" 270 win barrel with better precision. ( Royinidaho would be proud:D). Not BR match precision but I'm always trying to improve my loads. [/QUOTE]
