OK. sooner or later everybody using conventional carbide dies-one carbide ring-figures the case gets over sized. So, in one of my great reloading hauls there were two different kinds of dies for handguns. Both were interesting.
This is personal experience-YMMV: First up there were two vintage sets of conventional RCBS dies for 38 Special. Another for 357 Magnum. These were non carbide dies needing lubrication. Incidentally, nobody runs a case through my steel dies with no lube. These dies size the case retaining the taper.
The other 357 die set was the new fangled Lee with two carbide rings in the crimping die. New, those dies new are pricey.
I used the Lee set in a separate Dillon tool head. These dies make good ammo. Of-course I was shooting those rounds in guns that would have been accurate with cartridges having been being loaded on ancient Lee Whack-a-Mole dies-with the mallet. .
I ran the 38 Specials with RCBS dies in a RC the primed and loaded the cases in a 550. Sizing outside and loading inside the 550. These rounds were loaded to normal 38 Special levels for the informal match using both WC and SWC bullets.
Normally, loaded both 38 and 357 rounds with Dillon dies used start to finish. No, I have taken case measurements. Have I found any difference in accuracy? I could take these rounds sized differently mixed them up not being able to tell the difference. Now, for the acid test. I have access to the club Ransom Rest. Pushed to the max I can run a test there.
Personal bias: have a personal reloading rule. As you can tell there will be no running in circles with hair afire. If I'm looking at the net remember I;'m looking at the net! I may be getting something from the Twilight Zone. . Go look at Longshot's videos, So far, he has not drifted into Cloud Cuckoo Land. I recall one guru sharing how to adjust the primer system on a 550. Anybody who tried what he suggested was in deep do-do.
I'm gonna look at some video's now.
