that could be, i know ken watters in "pet loads" mentioned going not past that weight wise. interesting enough, he had two sections on 44magnum, in the first section pet load was 22grains of 2400. second section he reduced it to 21grains saying it shot just as well or better.
given the time he wrote that it would have been hercules not that in reality it makes any difference.
i would have to look at again, but seems some of the heavier bullets had trouble cycling in the ruger semiauto carbine.
one other tidbit not related to anything, when i bought the marlin rifle, i got a box of 20rounds of i thought factory ammo. I ran it through a chrony. those 240grain bullets were doing over 1800fps. That beats the velocity and weight of a 38.55.
Ken Waters also never realized H110 and 296 were the same powder, often favoring one over the other and stating so, in several chamberings......
