Ric, I have a 43 spanish carbine and my chamber cast shows a SUPER LONG neck. Like 11mm mauser neck. Like half inch too long neck. Body dimensions are exact to 43 Spanish. Just the neck is stupid long. I seated (sat) a lyman 385gr bullet on top of the case and its not long enough OUT OF THE CASE to reach the lands or even have its nose in the barrel. I couldn't breech seat as Id have a .25 inch air gap ABOVE the case mouth. CRAZY LONG!!
Is this the case with your 43 spanish roller?? If so are you shooting it like this??I have seen MANY threads on forums dead end, discussing the long neck situation. My brass is formed via 44-90 sharps brass. OOOPS--- I let the secret out. Its a dead ringer for fit and it has a neck more than long enough to accommodate my messed up neck or a standard neck. Its CHEAP. Forms easy. You will need to trim excessively but aside from annealing twice to protect the process, its slicker than goose crap on a hot day. If the P&^P(&^ LEE dies had sufficient length, Id have left the DAMNED neck full length and fixed the DAMNED problem. But the P(&^)&^)*& LEE dies are about a 1/4 inch tall and best suited for 22 Long Rifle sizing. My gosh the company is cheap with the material. At 2.250, my case mouth almost touches the threads for the neck sizer stem! Almost is .010------ a paper thickness. Ive got 30-06 dies (from 3 other companies) that can squeeze another .25 inch of neck longer than the 30-06 and not have interference. These Lee dies are a joke! CHEAP- and SHORT! I digress--- but the CORNER CUTTING on the new model molds and now dies from LEE is stupid! Please forgive my rant. I now they sponsor the site but my goodness..... Back to the problem.
Please let me know about your 43 neck. My friggin bullet just sits in a .465 neck space fully unsupported. If I stuff it in the brass, its a 1 inch jump to the lands. Man its bad. Thanks in advance. Mike
