I got to shoot my Bergara barreled Encore today. Very disappointing! Nothing but vertical stringing; and I mean three inches or more! I know the scope in on tight and it's a fine Zeiss. I'm shooting 110 gr. by vol. of BH209 and a Boat tailed 250 gr. Barnes with a blue sabot. Win 209 primers. Not the Win 7 primers. Tried another bullet and sabot , no change. I also shot 100 gr. BH209 with the Barnes and got a little better. Do you think I'm just not at the sweet spot in the charge? Oh, and no horizontal dispersion at all. I don't shoot this bad and neither should the Encore. It has a wonderful trigger and hing pin. It's tight. Any one suffer this before? What's up ?
