I was never able to get the 75grn Speer or the 86grn Rem bullets to expand at 25-20 speeds. The 70grn blitzkings certainly do expand, but with the low speeds of the 25-20 they hold together just fine. That bullet has a lot of empty jacket that upsets easily enough causing a fairly wide mushroom.
Would you mind sharing that load info? I have a friend who's father uses his 25-20 on our small deer, and this would surely be better than what he is using now.
