No ejector?

Calib,

What is your sport? You will get different answers based on your sport. They seem to come in and out of favor as the rules change.

The flat spots on the necks is new to me. I would like to learn more about that.

My sport with this gun will be mainly long range hunting, rocks and some steel, who knows maybe try some elr stuff.

Mgunderson - the neck flat spot is caused by the offset nature of a typical ejector, which pushes on the inner edge of the casehead so as to make the case neck move out toward the ejection port as you pull back the bolt. The offset spring/ejector makes the case mouth/neck fly toward the ejection port after it clears the chamber. The flat spot on the neck is simply where the case mouth/neck starts moving outward after it clears the chamber, but hits the inside wall of the action before the bolt has been pulled back far enough to allow it to cleanly fly out the ejector port. Even a very light ejector spring can cause this to happen. Resizing with a bushing die will not completely remove the flat spot; you have to re-open up the neck with an expander mandrel first. I'm guessing that if it was something you needed to be concerned about, you would probably already know; even mild flat spots are visually pretty obvious. However, if you think it might be an issue, check just below the case mouth with a concentricity gauge. You can do this before/after resizing to determine whether your resizing process is fully removing the flat spot.

most of the ctg damage (flat spot on the neck ) is caused with Remington or other flat faced bolt actions...cone breaching helps avoid this by alowing the spent round to gradually move to the side when using a spring loaded (M1 type ejector) ejector ,,,I replace the original spring with a weaker spring stock which cures most of the issues,,,,you can see that cone breaching not only helps to feed the ctgs into the bbl smoother ,,but also helps get them out (eject ) smooter too,,,the Kelbly TG ,,static,,ejector solves the problem entirely ,,,you can pull the bolt clear to the rear and eject the spent round or just part way back and remove the round by hand,,,,Roger
