If your chambers have no leade or freebore, the slightly shorter case should allow using bullets with a little more shank out of the case, if needed to hit the crimp groove.

That little difference or .1" will most likely make no difference to the average pressure generated - however, case capacity should be measured.

I recall in my old Rolling Block .45 3 1/4", that RWS cases held 6gr. LESS than did the Bell brass.

I used to load 122gr. 1F with a 580gr. PP bullet (.451" over patch) in the Bell brass, but for the same fitting load, ie: lube wad and card in the RCBS cases, 116gr. was all that would fit. I barely had more than .2" of bullet held inside the case.
