OK I know this just Wrong in so many ways :veryconfu
But it works ....and lowers my bar bill when others bet me I am full of it :bigsmyl2:
Well I know 9 mm and 380 ACP are not the same
Also they have different load data and head size
But in a screw up (by me) loading 9 mm with a Dillon 550 press
I loaded some 380 ACP cases with 3.8 gr of HP 38 and a 125 gr cast bullet ....slightly less than the starting load for a 124 gr jacketed bullet
But at the same OAL as the 9 mm load I was loading
So to not waste anything I shot the loads in my Glock 22 ...Err 17 .... I switched barrels
I also shot some in the High Power
Worked just fine
Extracted
Not as good of a group :cry:
Just had a different POI
Not in any way plan on shooting a any more of this loading as the 380 ACP case has a slight bulge IMO due to the chamber size
BUT I was just wondering what kind of change there would be in the chamber pressure
As both of the cases were loaded to the same overall length
But as the 380 ACP case has less case volume
I would think the pressure would be slightly higher
Thanks
