I did just that & commented on it in the other .38/.38+p/.38+P+ thread. It was a little heavier when weighed for the average of 4 cases & powder capacity was slightly lower, compared to "reguler .38" from the same maker. Probably because they had to keep the external dimensions so the thicker walls reduced internal capacity. A bit like the *groan* .308Win/&.62mm thing.
