Reloader 26 in 6.5 creedmoor

I'm curious about 130 Berger OTM, 130 ELDM and 124 Hammer Hunters with RL 26. Picked up 4 matching 1 pounders so I don't have to rob froM my STW RL 26 supply.

Give me some specs on your set up, COAL @ about .020" off lands, what Case and primer you are using, barrel length and I will run QL with those bullets using RL26.
 
Thanks

It's actually a 260 Remington but I use creedmore data pretty often for a starting load. 0.020" off lands COAL is xxxxxx 22" barrel, Nosler brass and Fed 210M to start.

I'll edit post with COAL tonight
 
143 eldx. With prime brass
Not sure the H2O of Prime brass in the 6.5 CM, some say it's about the same as Norma or Nosler so I will use 52.7 gr H2O

Remember to watch velocity, pressures run with velocity so even if you only used x amount of powder if velocity is higher or lower you use the pressure that goes with the velocity not the amount of powder. We can adjust the Burn rate for your powder lot after we know what your results are.
Also watch for the other normal pressure signs you always watch for while working up a load.
The 260 Rem is based off the max CIP 60,191 psi, the 6.5 CM has a Max CIP of 63,091 psi , so use your own discretion as to what you consider max. As well as the temperature that you are shooting at will change out come if it is barely safe at 60-70 degrees it will most likely be way over at 90 degrees.
