I just received this mold:
https://www.mp-molds.com/product/402.../?currency=EUR
Based the (non-dimensioned) reference drawing the nose eyeballed a little long to me. The description doesn't say anything about a specific OAL or intended cartridge. Being the adventurous type I said "meh" and clicked -add to cart-
Seems my suspicion was correct. Loaded to max OAL in the .40S&W it barely fits in a magazine, and in 10mm (my real purpose for getting it) the ogive is below the case mouth at max OAL.
Anyone know the back story on this one?
A) Was it perhaps intended for loading .40 long in a 1911 platform where you have the extra mag length?
B) Intended to load 10mm with .40 brass and pseudo-headspace on the bullet? Doesn't really seem to do this well as the loaded round slides in the throat without a firm stop, sized at .401" anyway. Maybe going a bit bigger would help but then you run the risk of scraping off the coating.
C) Just meant to squeak by in the .40 for some ill begotten attempt at a LFN longer range load?
D) Long loaded in a revolver? But also without a crimp groove.
E) Another cartridge entirely that I'm missing? This design pre-dates the brand new (at the time of this writing) 400 Legend so it would be something old.
Please ignore the wrinkled bullets. I'm well capable of making them pretty. This was just a quick run on a brand new mold to test my hunch on OAL
.40S&W
Top: 10mm case max OAL
Bottom: .40S&W case loaded at 10mm max OAL
Since I already have it I'll make some more and just shoot them. May work fine even if they look odd...
