Lrg or Sml Primer Brass -> Hornady American Gunner 6.5 Creedmoor Ammo 140 Grain HP BT+Primer Questio

[Rdlningcltchdmpr]

Was curious if the Hornady American Gunner 6.5 Creedmoor Ammo 140 Grain HP BT that you can buy in the 200rnd bulk cases is Large or Small primered brass?
Still trying to decide on going a DPMS GEN II in .308 then get a new barrel (understand the issue w/ the barrel extension/bolt being proprietary and have seen the pics to know the difference) or going AR10A size, but in the mean time I can acquire parts that will work with either route I take.

Primer Question - From all I have read, for the CM, the Small primer brass is what one wants. Now, for Primers, when I do start reloading, I will be reloading for a couple 5.56 chambered AR15s, possibly a Grendel (I say possibly because having a 6.5CM kind of makes having a 16" Grendel kind of pointless other than I just need a SA ADJ gas block and I have all the other parts and I like to build unless anybody has any other reason/s to have both a Grendel & CM?), is there anything wrong using CCI #41 Primers in everything since the will all be in semi-auto rifles? Or are Primers like other parts of the reloading cocktail with different powder/barrel/bullet/case combos working differently with different primers? Trying to keep amount of different consumables down to the least amount without sacrificing each rifles potential.
Same goes for powder - any chance of a powder working good in (worst case scenario if I decide to keep the Grendel) .223, 6.5G & 6.5CM?

As always, Thanks in advance for your expertise,
Bob

Small primer is not what one wants. They cause hang fire's when using ball powders, even with magnum primers.

@Dusty Stevens - 6.5CM & also .308 comes with both options too, both small & large primer pockets. I am just wanting to keep different skus down to a minimum. If the Rem 7 1/2 is g2g for both .223 & 6.5CM (which I believe it is), that would work out great for me

Ive never seen the creed or 308 brass with small pockets and large holes. Either way you need large primers with creed brass so youre going to have 2 skus on your primers. All hornady ammo and brass will be large primer. Theres a reason.

Just remember if you get small pocket creed brass pretty much every piece of range pickup and factory ammo you get will have large so youll be in the same boat as me with my 45acp brass with both primer sizes

I'm only 2,100 miles away from Phoenix. You can come over anytime to learn the ropes of handloading.



But in all seriousness... there are plenty of good video on bootube on reloading. But I also like the how to section in the reloading manuals. They're very good for beginners and they also touch up on some more intermediate reloading techniques.

First manual I got was the Speer # 13 ???? (can't remember, but has a Ram Scull on the cover).
It was good read, and if it was the only thing I had to learn from, it would be more than enough.
I think Speer is on their #15's manual. Hornady and Lyman are probably better than the Speer when it comes to explaining the "how to"

Appreciate the info, as others had contributed earlier, looks like I will going to either a bookstore or Amazon and getting a few manuals
