Im also for the 120-125 gr range with my 6.5cm for all around hunting.I like the flatter trajectory with nearly as equal wind bucking as the 140to 800. I also like less recoil for followups.
I think if you want to shoot a 'heavy' in the cm then use the 130 as thats what it is made for like the 6.5x47. The creed was designed as a target cartridge to shoot the 140's for paper and steel punchers at set ranges where trajectory was not a concern. So I think If you want to hunt long range with a 140 then step up to a 284/300 variant to match the weight with the punch and get the trajectory you should expect.
My 6.5 is a hunting rifle built for the 120gr range. 1:9. It will shoot .20in 100yd 5 shot groups with 120/123. Havent developed a 130gr load cause I like the 120's. If I wanted to shoot heavies then I would go all the way with the 150gr MK .713bc in a 7.5 twist and use a short action for field weight. Apparently the 6.5 SS is the answer for that. Can use a tikka action and get a 3in mag length as part of the package. Just add barrel and stock.
