I am thinking of ordering a lee neck sizing die for my ..243 and was hoping for anybodys input on them that have tried them.Do they really inprove accuracy that much.The gun shoots great now after full length sizing but after reading some on neck sizing and how it improves accuracy and extends brass life (without having to lube) they sound great to me.Any info would be great.
 
I use the Lee collet dies for practice ammo as it is very quick with no lube to add or remove. The ammunition is very concentric and slightly better than FL sizers I've used which should give better accuracy at least theoretically though I've not seen it.
 
neck dies

i have the complete set of Lee dies in 243 used them for about 100 rounds so far.I found the neck dies work great on my RSBS Press. They seem to be very good for fixing the runout on the cases as well.You can't go wrong for the money in my opinion.
 
I swear by these dies for all bolt action rifle reloading. I have zero issues with them and the price is amazing.

In my 223, I FL sized for the first time after 4 firings, and some of these loads are pretty hot.

Just make sure you never run a case through without the decapper installed. The collet will crush the case mouth and you'll ruin your case.



Also, as per the instructions, for extra precise resizing, run a case through then turn it 1/4 turn and run it through again. Helps with removing the ugly collet petal indentations too.
 
i just got a neck size die and a collet crimp die for the .243. I have noticed that when i take a loaded shell and roll it on the table, the bullet is very straight. When I full length sized, there was sometimes a wobble.
My groups now touch at 100 yards, so the proof is in the pudding I guess. I would recommend them.
 
I find these dies work great! Just make sure you dismantle it first and polish the surface on the mating taper parts. The factory finish can be a little rough, which leads to a slightly 'rough' feeling when re-sizing.

So, why use them for only "practice ammo"? With the advantages you list, I'd think one would use them for all ammo needs.

If someone had have asked me a month ago about lee dies, I probably would have said "don't but that $hit, get some Reddings or Forster"(because ignorance is bliss of course).
I just started reloading for a friend of mine and on the advice of another friend at Wholesale Sports I cautiously advised him to buy a Lee Deluxe set.

WOW! To say that I was extremely suprised with the results would be a gross understatement. I would put these dies up against any of my Reddings or Forsters. They seem to be very consistent and concentric(the rounds).

I was very impressed with the results to say the least and would not hesitate to recommend them to anyone.

I get around 2 inch groups of 10 shots at 300 yards in my 223 using lee collet dies. I use them in 2 other calibres and really like them. But I also find the redding nitride bushing dies excellent too.

I think the lee collet dies are something you have to try and see if you like em. A lot of reloaders are to some degree gear snobs. In that regard they would not even give lee a look.
You have to see if they work for you. But at the price they cost you really have nothing to lose but a few hours try out at the range.

True. But then make sure to read the instructions and follow them. They can be damaged fairly easily if not set up right.
 
Lee dies-use the collet all the time. I however use Forster for bullet seating as I like the design slightly better (have not tested run-out). I would however experiment with neck tension-I don't turn the Lee Collet a full turn after touching shell-holder and never crimp. My .243s, 22-250 and 270 shoot great using Lee...ofcourse neck sizing is only one of many variables to squeeze accuracy.

Once the brass has been fired repeatedly and becomes hard to chamber, I use the Redding Body Size die and a headspace kit to "bump" the shoulder back max .002". So, no FL resizing dies ever used...and I have mags, never had a problem chambering.
 
colonel we need more info. The type of gun is crucial. A semi needs to be full length resized everytime. A bolt gun can be resized every 5th time with the other 4 being neck sized.

If you are using the rounds to hunt, you should FL-size them, otherwise the c*ap you pick up in the field could be enough to prevent you from chambering.

This is my reasoning as the neck sized cases eventually become too snug and can be hard to chamber even with a little bit dust or debris on the shoulder. I always run my hunting cartridges through my gun before hunting to make sure they chamber easily and I have found some neck sized cases that were a bit sticky and when wiped off chambered more easily. I don't roll my cases around in the mud when hunting but bits of fuzz or dust are inevitable so I choose not to take any chances and FL resize.
 
I have used collet dies since the early 90's and never had any chambering issues and have used ammo so-loaded.

If I was loading for a dangerous game rifle where 100% reliability is paramount and that saw daily use in the field there is no way I would neck size but for all other uses in a bolt gun, Collet dies are great. As others have pointed out at some point you will have to FL size to knock the shoulder the back after a few loads.
