Problem loading .50 AE, bullets too loose

was based on a revolver and we had a sizer die that was too loose and the bullet would spin. I had another sizer die made to tighter dimensions and did a good strong taper crimp and no more problems. If you are going to do a lot of loading for Roman you probably should get a tighter sizer die made by Lee. They are the only company that I know of that will make up a special one of a kind die. You will have to give them all the data including case mouth thickness. Also check if he has more than one brand of brass and see what the case neck dimension is on each of them.

I have the Lee dies and the sizer always resulted in stuck cases no matter what I did or what lube I tried. I bought an RCBS .50 AE sizer die and that solved my ptoblem. I still use the Lee expander and bullet seating die with no issues.

My dies are RCBS. Never had an issue. Still have a couple hundred rounds but no gun. Someday will have to pull them apart.

Duck tape. A modern version of a paper patched bullet.

Dip them in a viagra solution before you load them?

Smack them with a hammer then resize them in a lee sizer

Buy new bullets

you ought to get him started on swaging his own bullets as well. At $2 a pop on factory HP projectiles, it wouldn't take too many to pay for the cost of a swaging setup. Plus you could order the dies to give you that extra couple thousandths diameter to improve fit.

I use an NOE expander die and buttons. It will allow you to adjust the amount of expansion of the case and will allow you to get as much bullet tension you need/want.

The LEE dies seem to conform with SAAMI specs that show a loaded round measuring 0.529" at front of the case. My loaded Hornady component rounds mic 0.526" (I know, but they just do). A total of 0.006-0.007" of case pull on the seated bullet seems a good number (there is only about 2-3 thou right now). So this makes me wonder about the brass. It would need to be only about 0.0015 or 0.002" thicker per side to make this up and everything work like it should (0.0014" rather than 0.0012" thick). This would be close to the SAAMI OD spec of 0.529" with a 0.499" bullet (in proportion to what I measure now). I'm getting a few thou larger on the OD than the literal math would indicate, maybe my measuring point, but it seems consistent.

Roman only needs a couple mags worth. SO I did something sort of crazy. The ONLY die I have close from about 100 sets is a belted magnum sizer (I used a .338). I squeezed down the 1/3 front portion of the case mouth to around 15 thou under. The SAAMI shows 0.529, Lee was doing, 0.526 OD, the .338 die sized the OD at the mouth to 0.511. My ID dropped from 0.497 to 0.485". Notably too tight but would it work with a bullet seated into a heavily chamfered case? Sort of. The result was workable but I was worried about concentricity and maybe a tiny bulge in the case. I gently ironed cases using the LEE sizer (on loaded rounds) with the decapper removed. Not FL but just to iron out any malformities. It seemed to work and is doable for an emergency on maybe 20 rounds.

The thick jacket and generous bevel allowed a gently forcing of the bullet into the slightly necked cases.
