PhotoRecon Posted September 29, 2009 Share Posted September 29, 2009 I typically load 9mm, 38 Special and 45 ACP on my RL1050. I also have the tooling to load .44 Magnum and switched the RL1050 over to 44 to do a small run of LSWC's. My 44 tooling doesn't see anywhere near the use the other calibers I have. I immediately noticed when loading 44 rounds that the expander die seems to expand the case more on my 44 brass than it does on my other calibers. My theory is that the expander on my other calibers is not as effective as they once were having worn down from use. Has anyone else noticed their expander die on the 1050 series wearing down over time? Does anyone happen to know what the 45 ACP expander die dimensions should be? Regards...

Aircooled6racer Posted September 29, 2009 Share Posted September 29, 2009 Hello: The expander die is adjustable so you may have to adjust your die. I have loaded alot of 9mm and 40 and have not noticed any wear at all. The oxide coating has worn off but the shoulder has no wear on it. Hope this helps.

I should have been more specific. I'm focusing on the lower part of the die below the bump that ensures the neck is uniform and in some calibers supports the case while the swager rod comes up into the primer pocket. The ones I have look worn but without a measurement from a new expander die there isn't anyway to tell. Regards... Link to comment Share on other sites More sharing options...
dillon Posted September 29, 2009 Share Posted September 29, 2009 On the 45 expander die, the lower portion that expands the case neck measures .454" diameter, +/- .001". Link to comment Share on other sites More sharing options...

98sr20ve Posted September 30, 2009 Share Posted September 30, 2009 (edited) On the 45 expander die, the lower portion that expands the case neck measures .454" diameter, +/- .001". Thank you... Regards... If it comes out the sizing die @ .454 +/- then the neck expanding portion won't do anything. If it comes out the sizing die smaller then that then it will open it up to that point. If it comes out the sizing die larger then that you could have some serious bullet tension issues. Edited September 30, 2009 by 98sr20ve Link to comment Share on other sites More sharing options...
