The 6.5 lends itself to problems with cast loads. The leads are LONG on these old rifles the twist rate is very fast so the heaviest, longest cast bullet tou can find that fits your lead would be your best bet.
i will be stuffing some cast loads through mine once I get my bullet sizer.
Was thinking about this mold

I have a 8mm mauser project in the weeds right so molds will have to wait
6.5 swede FMJ
Im going to say with the long lead these tend to have again the longest bullet with the most bearing surface might be the way to go.
I picked up enough hornady 140s and Barnes 140s to have some some fun. Been using Norma MRP
I have not done much of any load testing I cut the hi/low data in the middle and been playing there so far.
I dont shoot as well as Mountain and Im not sure how are rifles compare but Im floating around +3 moa with my eyes probably keeping this rifle from at least 2 moa. Shot today but the lighting was awful with that sun so low and in your eyes.
im loading my 6.5 bullets to as long as the mag will feed them and they are still miles off the lands
im not up on whats better for these old rifles, slow powder or fast powders.
Right now Im taking advice from a friends dad who is a swede and shot the target rifle version of the M96 for years. He claims you want to use the slowest powder with complete burn vs the fast powders with higher chamber pressure and burning up the powder early.
his words, “they like a good steady push vs a swift kick in the ass”
I have no idea but he suggested RL22 and Norma
Im setting up for 100-200 yards. So I dont think I need to velocity to get the accuracy I need
