4000MR in 6.5 Creedmoor?

[Hondo64d]

Just picked up a jug from Powder Valley. Better hurry, only two left.

Both Speer and Hornady have data for it but has anyone here tried 4000MR in the Creedmoor?

Thanks,

John

Maybe just a slight bit fast for 6.5CM and not sure you will get the % of case fill for best results.
Also, if it is anything like the few pounds of 2000MR I've burned in 308 and 223 then it is prone to small changes in density altitude making big differences in POI at longer ranges.
Good luck with it. At least it is powder.

Speer shows pretty good velocities with it so I’m hopeful.

@Alliant Reloading on this forum would be the guy to talk to on this.
It appears Hornady liked it with their heaviest 6.5 caliber bullets in the Creedmoor.

I have used it with 140-143 gr bullets.... certainly one of top 3-4 powders for 6.5 Creedmoor. Top end speed not too temperature sensitive what’s not to like.

I have shot many rounds thru a 6.5 creedmoor using 4000MR out to 1000 yds. . Using the 140g nosler RDF and the 140g Hornady ELD-M I'm using 44.0g to 44.3g of powder respectively. I'm also using Nosler brass and CCI 200 primers. I worked up starting at 42g in .3 increments. That's where my gun shot the best.
