I have a 96 swede for many years and never messed with it. I got the urge this past year to change all that. Shot some cast and its fun fun fun! But for where I hunted this year my longest shot would be 250-300 yards. I heard many say shoot only flat base bullets in these and what is a good proven(hunting) flat base bullet for a 6.5x55 ? I scored and yes it was 250 yards but had dismal jacketed performance.
