Couple of brass questions

1. Every once in awhile I find these small dents in the shoulder on my brass. Toss it, or reload and let it fore-form back?

2. I've noticed my die only sizes the neck down to the red line, not all the way to the shoulder. Normal?

When using bushing type dies the bushing doesn't resize all the way down to the neck-shoulder junction.
Most all S dyes leave about a 1/16"- 3/32" of unsized neck. That's with the collar adjusted to hear a very faint click of the bushing when the die is shaken. I have always inserted the bushing with the script facing down.
 
1. Could be a speck of dirt or carbon in your chamber. Cleaning it should clear that up. If it's after sizing, could be too much lube as others have said. Either way, it won't be a problem to load and shoot.

2. Pretty standard for bushing dies and isn't an issue. The Short Action Customs modular sizing dies don't leave that unsized portion because the bushing sizes the entire neck along with bumping the shoulder back.
 
I see some people saying it is normal because of the die. Come on. If the die design is normal than we're getting sold a bill of goods

Didn't see a direct response to this part of the question so - shoot it again, no need to toss it.

Re: length of neck sizing. That's how the die is designed. Redding goes so far down this road as to make micrometer adjustable neck-only bushing dies to pair with a body die for even more precise control over length of neck sized.

To really maximize the utility of this kind of die, you need to set the die high and shoot the case several times until it won't rechamber with neck sizing only. That means your shoulders have moved as far forward in the chamber as possible, and you can then set the lower half of the die for correct shoulder bump. Until this point it's normal for about half or so of the neck to not be sized while setting the die high.

Once you get the shoulders set, then you get into setting the upper half of the die for length of neck sized. The point of Greyfox saying he screws the collar down until he can just hear the bushing click around is to still let it float without putting the bushing in a bind, that will get you the most length sized that the die can do. You can adjust outwards from there if you want, or leave it where it is.

Different brands of bushing dies will leave different lengths of the neck unsized, it really just depends on how deep they cut the space for the bushing. As previously mentioned SAC makes combination neck/shoulder bushings to resize more of the neck while still giving the tension control of incremental bushings if you really want the full neck length sized.

This is correct I run SAC dies on my 6 Dasher and I have the Redding Bushing die set for my 6.5 CM. I run a separate Erik Cortina mandrel die. As stated by several over lubing and or dirty chamber will leave dents! Also if the rifle is a simi-auto the case may be hitting on ejection
