My Savage striker in the factory laminate stock weighed 8.5 pounds topped with a 6.5-20x40 Leupold. I used a cut down factory rifle barrel in .243, accuracy was on par with a good bolt gun.
I also used the factory 14" .308 barrel with a pistol scope and got phenomenal accuracy with 165 grain ballistic tips and 125 grain Sierras pushing the latter to an average velocity of 2874.6 fps. Neither of my barrels had a brake but with the rifle scope on the .243 you had to be careful!
I just sold my Striker and have gone back to the break open pistols but it was a fine piece, that's for sure!
