Here's my two cents worth for the 6.5 Swede but is not what you looking for, just an interesting topic. I reload numerous calibers with cast bullets and Trail Boss powder. All works fine until coming to the Swede. Using a max load of TB, the rifle will not stabilize even the lightest cast bullet available, let alone anything approaching a 160 gr. However using the same powder charge of TB, the rifle stabilizes any jacketed weight bullet you throw at it.
