I was able to make them to shoot in both a Marlin and a Model 94....MV was 2100 fps with a stiff charge of W 748... but reloaded those 5 cases 10 times each and the primers went in tight on the 11th time...so if there was added pressure, it didn't seem to hurt anything...
one of those don't try this at home things.. unless you know what you are doing...
