I agree with @BBarn , I think readjusting the dies may be in order.
I just did the check and dont feel any catching anything, feels smooth. So I guess I need to make an adjustment.
That line is the horizon where the brass head is so thick it doesn't expand on firing, therefor doesn't touch the sizing die. You could know that if you'd measure it.
I too have had a split but never case head separation. I guess time to adjust some things
If you have a generous chamber... as all my .45 Colt rifles seem to... that is not an uncommon sight.
I am using lee 4 die set for 44 mag and 44 special using a lee 4 hole turret press. I have two separate (same) die sets set up so I dont have to adjust for mags or special. I have not heard of this spacer before.Do you know where to get them?
On the other hand, I have had impending case head separations in 460 Smith and Wesson Magnum cases but that cartridge produces a much higher pressure than the 44 Mag if loaded to maximum pressures for that cartridge..
Thought of that too. Think I will
I know it's not the 44 Magnum but I do have .357 Magnum cases I have been reloading for about 15 years and still going strong. I don't load them light either, I shoot .38 Special ammo when I want light.
Enjoy, be safe...
I'm the same with the .44, if I want it light I'll shoot the specials. Although i have never loaded over max recommended for the .44 magnum rounds. I try to stay a little under. I think the hottest is 20g of A#9 under a 240 grain xtp, or maybe 23g A#9 pushing a 180 grain xtp (those are moven 2000fps+ outa the Henry) but still a grain under max. I feel better hearing from everyone for sure.
Incipient case head separation occurs in BOTTLE NECK CASES.
IT is caused by the shoulder being excessively pushed back upon resizing and then being blown forward during firing. Repeated excessive sizing results in case “growing” in length and the metal stretching above the head area.
Practically never happens with straight wall cases.
Those.44mag cases will crack in the neck area between the 30th and 110th loading, in my experience...
I’ve got some .22Hornet and .303Brit cases with incipient case failure rings I’ll photograph later... It’s cold in the basement this morning...
Some of the Hornet brass was new in 1977 when I bought my first Hornet.... still using it!
