Re: Do belts affect accuracy?
I've shot many, many rounds of 7mm mag and .300 Jarrett (necked down, "improved" 8mm mag cases) and found them to be very accurate. I also size them so that I am headspacing off the shoulder. I've had two 7mm hunting rifles, one bedded, one factory, that consistently shot in the .4's, with carefully worked up handloads. My 7.5 lb. .300 Jarrett shots around .5 if I do my part. They have worked for me.
