Anticipating my new CZ with a 1 in 12 twist, I am curious as to anyone's experience with lighter bullets in the .223. Most of the emphasis in the gun press lately has been on heavy bullets. I have a Savage with the 1 in 9 twist, but still stick to 50 or 55 grain bullets since the velocity drops with the 69 grain or heavier bullets.
My buddy has shot the Winchester 45 gr HP's in the 40-round white box from Walmart with great results in his Savage. The velocity is over 3600 FPS from his 26-inch barrel. If you use light bullets in your .223, what has worked for you in terms of bullet brand, weight and powder? I have a box of 45 gr Sierra spitzers, and would like to try the Ballistic Tips or V-Max.
