neck sizing question

I have a 6.5 creedmoor and lapua brass that i have full length sized trimmed ect. and now once fired. With a redding die set can i neck size only? If so how many times?
 
The brand of die makes no difference(neither does the brand of brass). It's how you set up an FL die that matters. Any FL die can be set up to neck size only. It is, however, an entirely trial and error thing to do.
How many times you can use any case depends on the load used. Eventually, any neck sized case will require FL resizing. There's no 'formula' for any of it.
 
The redding die set comes with a neck sizing die. Is it important to set the shoulder back a little every time? If I neck size only and it chambers smoothly in a bolt action is that all I should be concerned with?
 
Are you sizing for benchrest or hunting? Bolt or semi , what rifle . A quick answer is yes you can neck size but how are you measuring your cases and how hot are you loading. I reload rifle for benchrest shooting only , I F/L size only to .001-.002 max have my trimmer set to the length , I trim every firing after sizing.I like all my cases to be exactly the same in every way possible. Keep in mind I'm not shooting quantity only 30 rounds per range trip.
 
Just read you other question. Fired cases can get longer and wider , it depends on your chamber . Using your neck or full size die by just sizing the neck down to the start of the shoulder chamber that case if it chambers with no resistance when closing the bolt your good to go , some even partial neck size 2/3 of the neck. I tried neck sizing for awhile found full sizing much better. What tools are you measuring your cases with.
 
"...set comes with a neck sizing die..." That'd be way easier than fiddling with an FL die.
"...that all I should be concerned with..." Yep. Neck sizing means you don't fiddle with the shoulders. Only the neck gets sized so the bullet will be held securely. You will still have to FL resize eventually though.

This is a paper puncher. I would like to get out to 1000 yards and beyond. I found IMR4350 with 40.6gr and a 140gr Hornady VLD match produced a very nice hole with five shots at 100 yards. I am measuring cases with a Hornady dial caliper. I do not have a tool to measure shoulder. I'm guessing thats not a hot enough load to keep me from going transonic at distance but I am new to this so that's why I'm here.
 
For my match stuff now I full length resize using a Redding S Die with the expanding ball removed and no bushing then neck size using a Lee collet. I rarely see over .001 runout with mostly less than .0005. This method has given me the most consistent velocity SD's and lowest runout of any of the sizing methods I have tried.

BTW Peterson makes a very good 6.5 CM brass with small primer pockets and Palma small flash holes. Most of the 6.5 shooters at my club are switching from the Lapua for long range. I switched to their .260 Rem brass and will never again buy Lapua if Peterson is available
 
A Dial caliper with the Hornady Comparator's attached will help you find your headspace an ogive settings. Your looking to shoot long range , developing a load for that distance you'll need to turn out accurate reloads . A good rifle loaded with store bought ammo with a good shooter will get good 100 yard groups , LR is a different ball game . Ranges are maximum 200 yards in my area , that's hard enough for me to get tight groups.
 
Run-out is picture a straight line through the center of a loaded round an the tip of the bullet is off center. A bullet may look straight but is thousands off center. Just another tool to buy, it never ends.
 
what is runout? what is velocity SD's?

When measuring SD with velocity what does run-out have to do with it. I could see accurate powder charges even consistent neck tension with all rounds being as close to exact. Then wouldn't a chronograph have to be used to measure velocity or am I missing something. I found alot of good reading on reloading in this forum , people always willing to explain things I'm not sure of. Nothing wrong with asking , again an again. Thanks.

Why necksize? Almost all bench rest shooters now full length size. You would have to work hard to find a competitive bench rest shooter who is neck sizing.
Full length sizing does not necessarily mean screw the die tight against the shell holder and then go another half turn. On brass that is only going to be shot in one rifle, I barely bump the shoulder.

Neck sizing affects neck tension which affects SD's, Litz's latest has a whole series of tests on neck sizing and SD. The neck alignment has no affect on SD but does affect accuracy. You want whatever your method and tools you are using to do both
