Fotis - that’s a nice rifle. I think the buttplate design will temper your interest in heavy loads! I changed the buttstock out on my Browning 1886 to a shotgun butt style and that made quite a difference to comfort and handling.

The problem with the 45/90 is the lack of published pressure tested loading data. There is plenty around for the 45/70 but high pressure data for the 45/90 is hard to find.

CRS - did you ever have those loads you refer to pressure tested ?
