Re: .260 rem norma brass?
Remington .260 Brass, always a topic of "Hot Debate"!
Sherri Gallagher uses 260 to win championship
Sherri Gallagher just shot a record-setting victory in the 2010 NRA High Power National Championship, might also note:
"To capture her first High Power Championship, with a record 2396-161X score, Sheri used a Tubb 2000 bolt gun chambered in .260 Rem. According to Praslick: “[the rifle has] the same barrel as last year. I believe it has close to 2000 rounds on it.” To our surprise, Sherri’s ammo was loaded in relatively <span style="text-decoration: underline"><span style="font-style: italic"><span style="font-weight: bold">inexpensive Remington brass</span></span></span>."
Per above, if you also check the 6mmBR article on Terry Cross,
Terry Cross & Rem 260AI
You will find that he checked the specs on the Remington .260 Brass and found that 90%-95% of it was very consistent and well within spec.
I also shoot Remington Brass, and have been doing so for about 2 years now. I don't trim necks, I don't anneal cases, and I don't get into any other extreme or elaborate brass prep. I weight sort it, size it, trim it as needed, load it, and shoot it. Doing so, I have consistently improved my shooting.
Don't get me wrong, I would love for Lapua to come out with some .260 brass, but until they do, I will just stick with the Remington. I honestly have not done much with the Nosler or Norma, at this point I don't see a need for it given the increased expense. I may have to try some of the WW 7mm-08 necked down, sounds like it may be an easy step up from the Remington without greatly increasing the expense.
If you can consistently shoot sub moa at 1,000 yards, then I would take a serious look at your brass, until then IMHO there are going to be a lot more important things impacting your scores and group sizes. For me, I am sure my skill level has a much bigger impact on my shooting than the fact that I am using Remington Brass.
Best of Luck,
