Well, I decided to take the plunge and get into reloading.  I went with the Redding Deluxe die sets in all of my calibers, and I have a couple of questions...
 
1) Do I need to buy a crimping die like the one Lee makes?  Is crimping a good idea, or is it a bad idea?  All of my rifles are bolt actions (.25-06, .260, .30-06, .300 Wby).
 
2) Can I mix new brass with pre-fired brass when working up loads, or is this a bad idea?  All of my fire-formed brass has been fired only once (thus far) in my rifles, but I'm wondering if the fact that this used brass is of slightly different dimentions than new, unfired brass would present an inconsistency when trying to work up a load with both types of cases.
 
Thanks!

I have never needed a crimp on rifle rounds up to .375H&H. I don't see the need for it on the hunting calibers you have.
I always segregate brass by brand and how many firings. By number of firings I can keep track of the brass for safety reasons. Each brand of brass differentiate in weight and sometimes there are slight differences in internal volume because of this. Less volume with equal charges can create higher pressures. Again, this segregation is for safety reasons.
Good luck with your new hobby. It's a blastWink

My friend you have just started a never ending journey for perfection.

Reloading is very rewarding.

 

As for a crimp die. I would only do Pistol and anything in the RUM family and bigger.

 

I would keep all brass separated. Once fired, fired 2 times ECT...

It make life allot easier and will be much safer

GOOD LUCK and keep us posted on how it works out and the knowledge you learn on the way to finding that perfect load.

Thanks for the info on the crimping guys.  Can any of you recommend a good single stage press?  I'd like to stay with Redding in that I already have some of their equipment, but I don't know whether I need a turret press like the T-7 or a single stage like the Boss.
 
Thoughts?  Advantages and disadvantages?

redding is fine i myself like the rcbs rock chucker but i run all rcbs stuff, the nice thing about a turret is that you dont have to screw and unscrew dies all the time, but the heads on the turrets have some play in them, which can affect things, not  a huge deal if you dont shoot competition just because you have some redding equipment doesn mean you have to have a redding press either, i like a single stage because it makes me feel like i have complete control of the whole process

its not if its a good idea or bad idea, its if it is needed or not. some types of actions and guns are more "abusive". tubular feed mags, on levers, and semi autos if one is having trouble. I use one on a 7/30 waters win. lever. Additionally when reloading for ar15, sometimes the case mouth tension wanders, and a crimp die helps to even them out. It also helps stop set back. taper crimp dies work when set back may be a problem in pistols such as the 357 sig, or 45 acp.

hunting rounds are subject to little abuse and accuracy is the consideration. thus the least amount of deformation in the bullet possible is desirable and consistency of load, which rules out mixing brass.

I can tell you that the crimp that is milled into seating dies does not work at all.  At least my RCBS dies don't.  I hear that the lee factory crimp works, but have never used it.  I don't crimp my 338 win mag rounds and haven't had any problems with them.  If you shoot a bolt action load the  magazine full and after a few shots you can measure the OAL of the shells left in the magazine to make sure that the recoil hasn't pushed the bullet in deeper.  This I have learned so far, but I am also a newbie in reloading.  The single press is nice, especially if you have a lot of time on your hands.  It also helps to curve OCD, I hear.

from your question, my reference was to Lee only, rcbs and most others will fold the shoulder or ring the neck. ok whats ocd??

while a gun and related articles can be eye appealing, dazling and each different, reloads should be dull and boring -- no suprizes

I prefer a single stage because I'm into extreme accuracy and prefer to do things step at a time with no variation. Redding makes fine equipment and their presses are excellent. Once fired brass becomes the exact size of the chamber and as such will vary slightly from new unfired brass. I prefer to keep chamber formed brass separate from new brass. Once you really get into this you will find that neck sized chamber formed brass of similar weight will shoot better than new length sized brass of random weights. Be careful if you are OCD as this reloading thing can get real serious and you can find yourself getting more and more into honing simple ammo into the perfect loads.....

 I seldom  crimp for bottleneck cartridges, although I think it is a very good idea for heavy bullet loads in handgun or any dangerous game cartridges, as others have already suggested.
 The Lee Factory Crimp Die is great, and works consistently despite trim-length variations, unlike other dies which have a taper crimp feature built into the bullet-seating die.
 If you use taper-crimp seating dies to crimp, I suggest a uniform trim length, (which you want anyway!), and performing the crimp as a final and seperate operation to bullet seating. In other words, seat all your bullets without any crimp. Then back off the seating stem or remove it completely. Now, place a cartridge into the shellholder and raise the ram fully. Slowly turn the seating die down until the it contacts the rim of the case mouth, lower the ram and turn the die another fraction of a turn, until you achieve the desired crimp.
 The reason I do it this way is to prevent scrunching the bullet through a partially crimped case mouth in the last fraction of an inch of seating travel. It probably doesn't matter a bit , but it seems more sensible to me.  Therefore, I do it that way when I decide to crimp!

Rich,
Weather you resize the neck or full lengh of the case, Mic it afterwards to insure proper case lengh. If you only resize the neck, you'll need a universal decapping die for the primers, also always trim brass with the primer pocket empty.  And yes even if your not OCD prone "you will be, you will be!!!!!"   LOL

no doubt, then you will start putting your cases in your tray in order neatly stacked in rows with the head down on one case the next the head up so they all fit nice and smoothly yeah you will fit in soon!

 HA!  Wait until you experience the emotional distress of crushing a case while sizing it and realizing that you are now going to have one EMPTY slot in your tray!   Yikes

Why would I need a universal decapping die for a neck-sized case?  I don't understand...the decapper included in my Redding deluxe die set won't work?

Or worst stick a case in the blasted thing.  BTW: Brass melt at 1800 degrees F  hardened steel 2400 degrees F   Discolores the thing but it cleans it right out!!!!   Ask me how I know!!!   The decaping die is also normally the resizing die on a two die set.
 
you normally resize the full lengh while decapping.
 
 
My bad, depends on the die set you have.
