6mm creed QL please

[remingtonman_25_06]

Buddy wants me to load for his 6 creed so I'm asking for a bit of QL help. 26" barrel, IMR 4350 powder, he has Hornady 108g ELDMs and 108g Berger BT Target. Not sure on OAL yet, so well go with the factory of 2.790" Thanks for the help

41.5 grains of IMR4350 runs 2920 out of my 20” (1-8” twist) benchmark.

Thank you a ton Dr. Mike. I appreciate that! The rifle shoots under 1/2 MOA with the factory Hornady 108s, so it should be a shooter...The 4 shot group at 500 yards was 2" Almost not even worth the time and effort to handload for this!

Agree! It's one heck of a cartridge handloaded or factory loaded.

I've been using near max charges of Superformance and also H4350 with excellent results.

Danged Ruger rifle just keeps on slinging them in there at 600 yards.

I´ve done investigation on the 6mm Creedmoor, and I have to say, I like it.
It looks very promising on paper.
I think I will have to get one in a Ruger American Predator.
I do love the 6mm cal, along with the 6.5!
