148 HBWC and expander dies

Post by inthebeech on 10/17/2016, 5:42 am

First topic message reminder :

My expander ball is shorter than the length of the typical 148 grain HBWC.  I can feel the hollow base hitting the smaller "unexpanded" inside diameter as I seat them home.  Is this hurting my accuracy?  I am loading these at about 740 f/s and I usually buy soft bullets so the pressure may still be swaging them out to properly fill the cylinder throats and then also the barrel groove diameter.  I don't have a 'serious' leading problem which means a very slight amount shows up at 40-50 rounds, and my cylinder throats are .001 inch over barrel groove.  I'm sizing them equal to cylinder throats or half a mil under.  While my skill level is not sufficient to determine how accurate the revolver is, I do believe that I will be able to detect improvements in leading and accuracy.  This is more of a question about following established practices regardless whether I personally can detect their benefits.
I'm just curious of I could do better than the above in terms of less leading and maybe also better accuracy.  If so, is there a particular brand of die famous for extra long expander balls.  I realize that I can simply seat the bullets out enough to stay within the expanded portion of the case and I have done this but accuracy and velocity spread suffer.
Thanks,
Ed

Andrew,
he spun one out for me in about a couple days. just contact him via ebay and he will get it done. It seems like it will work as well as the .45acp die but I haven't used it yet since I haven't needed to load 38. I mic'd some key points and he built it to the numbers I requested.

Robert, I think i might just wait until you run it a bit to see if you are happy with it. I assume you are loading flush 148's on a dillon 550, correct? I have been loading magnus swaged which measure exactly .357"
Thanks,
Andrew

yes, the Remington 148 HBWC on my 550. I can try and run some sooner than later. I have it installed in the press I just never made the final depth adjustment.

after further review! I think he tapered my die a little too much. it is only .360 at the very top and tapers down to .357 by the middle. a .360 bullets only sits in .010 before it's too tight so that will probably squeeze down a bit at the hollow base portion. maybe, maybe not? I don't see myself reloading in bulk or using any .38 for quite a while to really test it all. hope this helps.
