First of all, let me say that I deal with Savage on a daily basis, and I know all the people who work in customer service. Eric is a really nice guy, but he is new. He handles complaints the way he was trained. He does not work on guns, he only fills orders and tries to help customers that have problems that he is trained to solve. Evidentally the standard procedure for ejection and extraction problems are to replace parts until the problem dissappears. Like I outlined before, the problems that arise with extraction and ejection are a combination of parts with accumulating tolerances. Sometimes a different extractor will fix the problem,with a tolerance of a few thousandths, it's all it make take. The gun manufacturers cannot control the size of the ammo, and if it's not close to mean specs., so the manufactering tolerance in the bolt face diameter has to be accomodating for wide tolerance.

Now for the good news......

Since I have been receiving many calls with this problem, I began to study it closer. I have done many different things on various guns to remedy the problem, which included: making custom extractors, opening up smaller bolt faces to the correct diameter(.223 to .308) , making larger ejector pins,and I even bushed a bolt face to reduce the diameter to correct size.
Then I tryed something yesterday that made sense, and it is very simple. First let me explain.
The spring pocket diameter in the bolt head (under the extractor plate) measures .150". The extractor spring measures .145", but the detent ball only measures .125". When the detent ball is centered in the detent of the extractor by spring pressure, it has .025" clearance between it and the hole dia. This make for side to side slop that will not compress the detent ball and spring. When a cartridge is pressed in the boltface, the extractor,ball and spring can be deflected approx. .0125" before the detent ball compresses the spring. The result is that amount of movement will not spring back to center, essentially leaving the extractor claw not grabbing that much of the case.
Is everyone following me on this?.....the fix is simple, use a bigger ball.
I have some in stock, they measure .140", thus reducing the non-returning slop.
I have tryed this on several here in the shop and had 100% success rate, although there may be a combination of factors out there on a rifle that it may not help, but it sure as h#ll won't hurt. ;D
