I did a whole bunch of research on yankie websites earlier in the year to suss out some decent reduced loads for both my 260 rem and 7mm08, for mrs and kids etc.
The general consensus was that the H4895 doesnt work that well (loading down to a min of 60% of the max load for any cartridge that has H4895 load data).
And then i spoke with a chap in the US, that got the load data for the factory remington reduced recoil loads, and they used 30gr of IMR4198 behind a 120gr bullet. I did some initial testing in both 260 and 7mm08 at around the 30-32 gr mark, and was getting about 2200-2400 fps velocity in both cartridges.
I also tested the H4895 reduced loads in each rifle, and the IMR4198 reduced loads were way more consistant with far better grouping. I had no such issues with hangfires.
The 6.5CM is not too disimilar to a 260 rem really, im picking you may be able to use the IMR4198 in that too, but it'd pay to do some more homework first.
