I think this would be an excellent idea - but I'd press them and see if they're going to make the actual 25-45 Sharps die.  If they don't, I think the 6x45 will work fine.

  I found an issue with the Lee Seater Die & its why I want to go to something else . Its not a big deal , but with these SGK HP Bullets  ( had no issues with the Speer Hot Core 87 gr. lead spear points )& the semi floating seating stem of the Lee Seating Die , it will sometimes catch on the Stem rim & not seat into the Stem , it catches on the outer rim , because the Flat HP of the SGK . The case & Bullet only have to be out of alignment a little for the Bullet to catch on the rim of the Seating plug . This may be because the floating Shell Holder of the MEC Press , but the way the Lee floating Seating stem is allowed to float with out a guide at some point in the beginning , can be am issue if you don't catch it . I could see a deeply seated Bullet if you are not on your toe's.

    The Forster is set up much better , as the photos show  below . The Bullet is held with the case & guided to the Seating stem .

    Die Body , Case/Bullet Guide , Spring , Seating Stem & Seating Stem Body

  The Spring hold pressure on the Guide all the way into the Seating Stem Body

  My concern is the small difference in the case 's may not hold the Bullet/Case in proper alignment . I do have the Seating Die in my Shopping Cart , so when I press the Button we will find out  how it works .

    I also need more Brass formed , I have these below to do some accuracy testing & finish breaking in the Barrel .  26.3 gr. H335 & CCI Primer with 90 SGK .  Meets my 2700+fps threshold & has the most consistent ES & SD

 ... because the Flat HP of the SGK .

This, right here.  That is one FAT hole in the end of that 90SGK.  I was surprised at that, looking at it face to face...  I'm running the RCBS dies for this caliber in a 12-year old Rock Chucker single stage, and I'm not having any issues, thus far.  On that note, at this point, I haven't loaded a whole lot of ammo for this thing yet...  :thumbup:

  I'll disassemble the Lee Die today to show how its a little loose in the Die Body , not a bad Idea to have it floating , but not for some Bullet designs . I catch it when it hangs up , but it slows the process down making sure the alignment is good enough for seating .

  Until they come out with something better , this 90 SGK is the Bullet for me to load in the 25-45 Sharps , so I have come up with something .

Here is the Lee Seating Die disassembled & its a decent idea to have the Seater plug floating , I believe there should be a Guide for it , at least to a certain extent , because it just flops around inside the Top adjuster .

 Look how much play is in the Seater Plug in the Adjuster & the Die Body, there is no guide for the Plug .

    I tested a couple of the rounds loaded with the Lees Die & the one seated with the Forster with my Concentricity gage , at the Bullet of the loaded rounds  & there was no difference in run out between the two , all had a total 0.003" run out , some could be the Bullet . I get a total of 0.001" from Sierra Match Bullets in a 308. 

  I will do some more testing to see if if the Case neck is causing the run out or the Bullet & or both.

      I sighted in the Scope on the 25-45 Sharps today , on a very gusty wind day , had my meter going crazy , it would steady out between 5-7 mph & then go up to 20 mph real quick & drop just as fast in a blink of an eye . 

     The 90 gr. SGK bullet with H335 @ 26.3 gr. , WW primer & they shot real good , as I wrote in the James Madison Trigger review , ten shot groups , were not small because of the wind , but a lot of them were in the same 1-2 " hole , with that funny wind.

     I think the combo of Ammo, Rifle & Trigger did great .
