JaviPT22 Posted February 15, 2011 Share Posted February 15, 2011 Looking into making the dillon 550 more precise with bullet seating/ case resizing for 308. Anyone have experience with the uniquetek's setscrews for the toolhead? Does it work? There is a fair amount of wobble, which doesn't bother me when loading for pistol. Thanks in advance for the advice. I am looking for every way to keep using the 550 if I can... Link to comment Share on other sites More sharing options...
Powder Finger Posted February 16, 2011 Share Posted February 16, 2011 Not sure about that product but you may check out Whidden tool heads. The dies float so as long as the shell plate and die holes are aligned the die can "wiggle" a little to self align with the case. I have used a floating die setup for quite a while and it works well, good enough for David Tubb anyway. Link to comment Share on other sites More sharing options...
VegasSean Posted February 16, 2011 Share Posted February 16, 2011 You may want to repost this question (or ask the mods to move it) to the Dillon reloading section. A wealth of information in there, and it may get overlooked in this section. Link to comment Share on other sites More sharing options...
Ken Kwiat Posted February 22, 2011 Share Posted February 22, 2011 I believe the CNC machined toolheads sold by Uniquetek are the Whidden ones. I have about four-five that I use for LR rifle on a 650 (using the screws to attach). I think it has taken some of the play out. In my case I just wanted to be able to use my 650 as a semi-progressive for the LR reloading that I do. Didn't want to free up more bench space for a single stage when I have three perfectly good Dillon progressives. I also did the rotary bearing tweak that was talked about on the Reloading forum within BE. The CNC toolhead plus bearings seemed to have smoothed it out and I get great LR results.

Scott Steele Posted February 22, 2011 Share Posted February 22, 2011 I only reload 40 S&W on a 650 but I do use the Unique Tek set screws and found it to shrink my OAL margin. Link to comment Share on other sites More sharing options...
All-Gator Posted February 22, 2011 Share Posted February 22, 2011 You are asking about the inserts and screws, right? I use 'em and haven't experienced a noticable difference. With that being said, they do take out one potential source of slop. A-G Link to comment Share on other sites More sharing options...
JaviPT22 Posted May 6, 2011 Author Share Posted May 6, 2011 Thanks for the above advice, loading .308 for precision shooting. notice an improved average OAL with the whidden toolhead and set screws. Can get oal's of 2.800 to 2.802 using the same headstamps. Link to comment Share on other sites More sharing options...
427Cobra Posted May 15, 2011 Share Posted May 15, 2011 COAL is effected by inconsistent tips on most bullets, if you want maxium accuracy sort your bullets by Ojive and Bearing length and seat by Ojive length. I use 2 of each of these to sort bullets and 1 when seating, remember you said percision. http://www.midwayusa.com/viewProduct/default.aspx?productNumber=709931 http://www.midwayusa.com/viewProduct/default.aspx?productNumber=724733 Link to comment Share on other sites More sharing options...
