Alpha, Lapua, Norma or Peterson 6br Brass

[Jo_Smith]

I have done the thing we all do and bought all four brands of brass. I am trying to get some advise on what the general feelings are about everyone's favorite brass or some ideas of what the best way to go.

I have been reloading and shooting for a long time but the 6BR is a new world for me. I have used Peterson brass on my 6 Dasher because it was the only brass I could find when I got the rifle.

Thank you for the help.

I like Peterson but I cannot say it is as good as Lapua YET.

I love Lapua brass, have used alpha with good luck as well and hear amazing things with Peterson

Its funny, or say ironic you bring this up at this time. Just this morning, I loaded up 20 rounds of Lapua, and 20 rounds of Alpha 6br with my proven load in this barrel. Shot two ten shot groups at 300. My alpha loads shot a inch smaller.
Going to do the same thing tomorrow.
I haven't shot any Peterson brass in about 3 years so idk bout them now. I know lots people like em.

In that order.

Watch your neck diameters. They’re all different.

No. I mean the outside neck diameter vs your chamber. You don’t want to shoot a .272 loaded round in a .272 chamber I promise ya.

Coming from a guy that shoots all Peterson in varmint guns...... I bought Peterson in March for dasher since i couldnt find any Lapua.... lets just say after your first firing weigh each case of Peterson and that will make the choice for you...... TONS of variation among the same lot. Lapua is available now so for BR i would go that route.....

I'm Having to Anneal, after, the 3rd shot of, Peterson 6.5 Creed, Brass ( NOT that big of, a Deal ).
Accuracy is, "On Par" with, LAPUA ,. in My Rifle. ( There was NO Lapua Brass, when I got the Rifle )
We've Had, great Luck with, Lapua, Peterson, Norma and ADG Brass, in My Family ( Never tried, Alpha ).
OLD Rem and Win Brass, still shoot's Fine, in my .22-250 ( LOL,. Brass from, the Mid, 1980's ! )
Back when, American Made Brass,. WAS still,.. Awesome !

Case. Capacity is a grain less in Alpha than Lapua and I shoot short range club matches against a bunch of ppc shooters.
It makes a difference no doubt.

I was curious about the statement regarding Peterson annealing.

 

[NC/Br Shooter]

I was curious about the statement regarding Peterson annealing.

Just the batch I had one time.3 or 4 years ago.
Was extremely hard stuff . It taught me how to aneal that's for sure. Iv talked to another shooter who had a similar experience, that's only reason I mentioned it . Id still buy some though if I needed.

Cant go wrong with any of alpha, Lapua or Peterson if you size every time and trim all ovem the same.

 

[jackieschmidt]

The Peterson is too thin In the necks. Here is the loaded Pertson compared to a loade Lapua.

If you shoot the Peterson in a no neck turn .272 neck chamber, it will have at least .006 clearance.

Would it have hurt them to make it the same as Lapua?

 

[NC/Br Shooter]

That would reason why the brass would get hard then. I shot mine in a 272 chamber when i had it.

Not an extensive study, but from a measurement standpoint, at least the necks of Lapua (blue box) and Alpha OCD 6BR are very comparable… (I only took 5 readings on each of 5 pcs… but, pretty telling I think).
Average neck thickness:
Alpha 0.01263
Lapua 0.01283

Average range (neck thickness) within case:
Alpha 0.0005
Lapua 0.0004

Maximum range (neck thickness) within case:
Alpha 0.0008
Lapua 0.0007
