About the revision in the case and reamer prints, and
about hydraulic forming die setup we made, for 375 HE,
Saves a lot of time and powder, and gets them to chamber size.
The cases we and others necked had kind of what is called
small love handles or donut, at the shoulder. If we tried holding it
all in at the shoulder case too thick there when looked at
by sectioning case . Even when we sectioned them to check
after firing, But doing them in the hydraulic die, which is adjustable,
with debth changes in the die, we was able to get shoulder looking right, by stretching
out the donut, and shoulder forward, gained .020" length to shoulder, so
made our test gun chamber longer, leaving belt step in same place,
from base to shoulder to match, after firing, were better at the shoulder when sectioned,
IE looked better on the inside of case sides to shoulder corner,
and that is how we got the revision for reamer figured out best.
Then got all reamer prints at Manson, PTG, JGS, updated.
Case forming easier, proportions better, little more volume.
Our hydro die, we made adjustable base, made things lot easier.
In essence an adjustable chamber.. Ed
