Neck sizing ONLY w/ Redding TYPE S FL bushing die?

[RodneyDowns]

I'm about to order the Dies for my new 260 abut would like to know if I can use this http://www.midsouthshooterssupply.com/item.asp?sku=0007636531
for neck sizing only for 131.00.
I can get this http://www.midsouthshooterssupply.com/item.asp?sku=0007638531 for an extra $20.00+ but is it needed?
I dont see why I would need 3 dies if I can use the FL die to just neck size only.

Am I missing something?

You cannot use a Full-Length die to size the neck only. That can only be done with a "Neck-sizing" die. FL dies will size the body and the neck (if you have a bushing in it).

I recommend that you get the first set you mentioned above to get started. Then add a Type-S Neck sizing die if you wish to neck size only. I don't see the need for a micrometer on a neck sizing die. The micrometer is awesome on the seating die.

Ive been doing some searching since I posted this and found some information suggesting that for best accuracy and case life to use a body die that doesnt touch the neck, then a Lee collet die to resize the neck, then the competition seater. Part of the thought being that a neck sizer that uses the button with the deprimer streatches the neck out more.

Yes, I agree. Less stretching = longer brass life. I don't have much experience w/ Lee's collet dies. But I do like the fact that I can control the neck tension w/ bushings down to the .001".

I usually deprime in a separate step w/ the Lee's decapping die. So, I removed the deprimer/expander stem from the Type S dies. Redding actually give you a extra smaller expander cylinder piece so that it will not touch the neck at all and still deprime.

I haven't noticed any difference in accuracy between neck sized and FL sized brass. But, I don't shoot F-class or benchrest. For the sake of reliability and safety, I decided to FL.

Actually, it is generally considered that if one takes a Full Length sizer die and sets it up so as to not bump the sholder, it is operating as a Neck Only die at that point.

I do get your point about some of the body being sized (a little) when the die is used in this maner, so I'm not calling what you wrote incorrect, but it is not quite correct either.

So, you are telling me that a FL die can be used as a Neck size "Only" die, even though it sizes the body "a little"??

I think what you are referring to is "partial full-length sizing". I didn't want to bring this up because I know the OP is fairly new to reloading. From my personal experience, when you FL size the brass, the body gets squeezed circumferentially, the brass will grow longitudinally, which means the headspace increases. Then, the shoulder get bumped and finally the headspace will decrease to the desired length. This is usually a bit shorter than the fired-formed headspace length to ensure proper chambering. I just can't see why you want to NS using a FL die and risk increasing the headspace to a unwanted length?

Thanks Shootist2004, But I would still need to buy the comp seater and its 95.00+ so I would still be around the 150 for the full set new, and I would have to pay two shipping charges as well.

Thanks though

I am not new to relaoding at all. Been reloading since 1992. I am new to precision reloading though. I have always used just the standard rcbs dies and want to up the quality and get into 1000yd competition.

I know exactly what MitchALsup is talking about. Hes talking about using a FL sizer die and lowering it to just above where it contacts the shoulder. That still neck sized most of the neck. Its how I neck sized my 223 and 22-250 for years.

Ive always been in the NS camp and believed that NS gives better case life and better accuracy. I'm not as sure now about the accuracy part but it still makes sence that it gives you longer case life.
I did a lot of reading yesterday and found a few people stating that FL sizing made for better accuracy, but they ALL stated that it was at the cost of less case life. Many others claim NS gives better accuracy and better case life to boot.

ive also read that partial NSing is better than full NSing and vice versa. Not sure what to believe there or if it even makes enough difference to matter. I think some of the minute technical differences are more based on technical theory and not so much on actual measurable results.

I shoot mostly at 100-600m. So, I don't need the level of precision for 1000yds comps. I do have a sinclair neck-turning kit on backorder that I intend to try out and do some testing with regards to neck tension.

Yes, if you google long enough, you can find opinions and theories to support anything you want to believe in. I try keep an open mind and go with what makes the most sense to me.

The full length die will bump your shoulder back depending on how much you desire. The setup is important. Using redding competition shellholders can help ease setup pains.

I spoke with the folks at Redding and they said that partial neck sizing, while done, is fairly boutique. I do neck turn though and it's useful for a variety of reasons, but it depends on the quality of brass you begin with.

Because you don't have a NO die, and want to run a NO reloading experiment to see if you want to buy a NO die.

They said fairly boutique? They might wanna change that on their tips page then.,,
