6.5 creedmoor 130gn TMK

[jbs2014]

anyone here have any decent loads for the 130 grain Sierra TMK in 6.5 Creedmoor? I want to get the bullet to at least 2750 FPS. I have a factory Seekins Precision AR 10 with a 22" Barrel, and I can only get 140 grain bullets to 2600 before I see pressure signs. I figure a 130 grain TMK at 2740 will do a bit better. I have federal match primers and some Superformace powder on hand

Thoughts?

Thanks for your time

What powder have you used? I have a 24" barrel and am getting 2860 using H4350...seems like low velocity but it may be the powder you are using or could just be the rifle.

You get that velocity with a 130 grain?

No, 140gr...

I get 2,860 ft/sec with a 135gr Berger over 47 gr of RE26 in a SRP Lapua case, fired from a 26" bbl. There is probably still some room for increased velocity but the load shoots so well at 400 yds that I never bothered with heavier charges.

I will try that next, I am testing Peterson brass and superformace powder today

Could try RL17. I get good speeds with 129 grn Hornady bullets in a 20" barrel. Right around 2800 fps.

RL17 was on my list, thanks for the info. When they have it in stock around here I will pick some up

Thank you

What primers you using? I have the federal 210ms

Same here.

So I guess I exceeded my intent of 2750 by a large margin. I had pressure signs on the last one so I did not shoot the last string. My velocities were 200 FPS faster than what the hornady book said. I was using Peterson brass this time around as opposed to the hornady that I used with the 140s and H4350. The high pressure group was the best.
