Home Forums Reloading Big Game Rifles 143 Eldx in 260

I am sure this has been covered but I can not find much information
Does anyone run ELDX 143 through 260,just looking for suggestions and starting points,none of my manuals mentioned the combo
Thanks
Rifle is a Tikka T3,1 in 8

Look at creedmoor data. H4350 and R 26.

The Hodgdon reloading data available online has data for the 260 and that specific bullet.

H4831sc also would work well.

I'd just use
I'd just use 142/144gr Matchking data, which should be plentiful. Even 140gr spitzer data should be close enough to get started. For speed, RL26 is going to be a good one. I'd be expecting just under 2800 in a 22"+ Tikka barrel. I made 2750 with a 21" factory Bergara barrel and 2650 with an 18" factory Sig barrel (both 6.5CM of roughly same capacity).

Thanks for all the advice
