  1. It doesnt not have the sizing ring nor the adjustment knob. Its a collet but its different from a normal rifle die.
  2. I've been playing around with this die for a couple days now and I can't seem to get any crimp out of it. Im using a 550b and im to the point where I barely do any belling to seat the 125gr montana gold bullets so I can get as much neck tension as possible. I followed the directions as they say to screw the die till it just touches the shellplate, then halfturn more. Ive done that and ive even gone as far as camming over and i see now evidence of any crimp ring or anything. Could it be a defective die or something? One other thing I found not clear in the instructions is when they say screw die to touch the shellplate, there is some slack in the bottom of the die, so im not sure if they want me to screw the die till it stops or what. anyways, any help would be appreciated.
  3. Ok, i'll try a little more cam over like you said. Is there maybe a better sizing die than the dillon which doesnt require so much cam over? also, when you have cam over, does this mean i have to re-adjust the rest of my dies?
  4. You don't say which sizing die you're using, or whether the 0.001" "growth" is in overall case length, but ... I've experienced this problem with Dillon sizing dies in both .223 and .308. Even when screwed into my 650 enough to produce a slight "cam-over" of the operating handle, they would not push the case shoulders back enough on FIRED cases to pass my Wilson case gages. (If the 0.001" growth you mention is in overall length - as opposed to base-to shoulder datum - not at all uncommon when squeezing fired brass into a resizing die) Opinions vary, but I've had great results using RCBS small-base sizing dies in station 1 for FIRED brass. For PROCESSED brass (such as that sold by Scharch Mfg and others), the Dillon dies have proven suitable for neck-sizing in station 1. YMMV. When I care enough to send the very best (read that as heavy bullet long-range loads), like Tom D, I do all case prep on a RockChucker... I'm using the dillon sizing die. The brass is once fired. I first take a measurement using a stoney point headspace gauge with my calipers that measure off the datum and them run the brass thru the sizing die and take a measurement again. it seems to either stay the same or grow larger. I even set the die to even cam over just a bit but no luck.
  5. hey, i got a question. Im trying to set up my sizing die for 223 on a dillon 550b but i cant seem to understand whats going on. I set the die so that it just touches the shellplate. i bought a headspace guage to measure some once fired brass that was shot out of my rifle. So im assuming i should be setting the sizing die so that after resizing it should be .001" shorter. But it seems how ever much i play with the die it doesnt change and it seems to get larger instead. any idea how to go about this?
  6. great info guys, thanks. ok i got it now. So in other words, the measurement i got from the oal gauge and comparator is 2.012. if i subract the .020" jump that is common in ar15s then that would put me at 1.992 which is around 2.318 oal without the comparator. Does this sound correct? Sounds like i should just use the comparator and set it at around the 2.260 oal and be done.
  7. its an ar15 that im testing this on and it is a stoney point oal gauge with a 223 modified cartridge. I know this is prolly overkill for this rifle but i thought id try it out. its almost like the case isnt going all the way in.
  8. OK I just got my oal guage and im a little confused. I screwed on the .223 case and put a 69 smk into the neck. grabbed my upper and slid the gauge in. I carefully pushed the rod in until it stopped and tightened down the thumbscrew. After pulling out the gauge it appears the bullet is barely in the case. Using the stoney point comparator i get a reading of 3.018. Im not sure if im supposed to account for the 1.000 that the comparator takes up or not. Can someone fill me in on what im supposed to be doing here? I know that comparing the length of this to a factory load at 2.260 oal is much shorter that what this looks like.
  9. 2 of the fl dies are steel which i use for rifle and i have 2 others that are carbide for pistol. im using a dillon 550b. Thats pretty much how i did it but i keep reading about taking headspace measurements and adjusting to get that right so im a little confused. I did notice when i ran some 223rem in the sizer die the length of the casing seemed to have gotten just a tad larger while my 260rem seemed to shrink, is this normal? IN A PROGRESSIVE, FL steel dies can be adjusted as described previously (touch the shellplate, plus 1/8- to 1/4 turn so the handle "cams over", then tighten the lock ring). Carbide dies should JUST touch the shellplate, then, run an unsized case into the die, check for the barest sliver of light between the die mouth and the shellplate (there's enough spring in most progressives to ensure this), and tighten the lock ring while the case is still in the die to ensure concentricity. You don't say what you're running your 223's and 260's through, but common wisdom is to full-length-size any round going into a pump, auto, or lever action. Most quality dies will NOT oversize cases (e.g. push the shoulder back too far), and, unless you're looking for benchrest accuracy out of a bolt gun, this generally isn't a concern. However, adjusting your sizing dies and checking with a headspace gage (e.g. L.E. Wilson, et al) is generally a good idea. 223's stretching is a common phenomena - shrinkage is unusual... YMMV... ok, this info helps alot. The 223rem and 260rem are both run out of ar15,ar10 rifles. ill follow your instructions and go from there. thanks

  11. Ive got redding and dillon FL sizing dies but I don't exactly understand how im supposed to adjust them. Can someone fill me in with how to go about properly adjusting them. thanks
