That's the plan.Is that what you’re shooting for nrl this year?

What kind of numbers? ES/SD looks worse and worse the bigger samples you shoot, my initial 10 shot on my proof group had an ES of 62 and SD of 24. That 10 shot group went .6", and I never saw anything notable from velocity show up on targets out to 1,000. I honestly quit caring unless it's obnoxious like LRT in 28 Nosler, 128fps ES for 10 shots. Wouldn't trust that lol.Prepped about a hundred cases. And loaded up 30 rounds of the best shooting stuff of the day to check ES/SD again and shoot to distance.
This is my second time shooting my reloads (first was two days ago). I can see where people start chasing their tails. I had a 5 round group at 1” last time but with awesome ES and SD.
Today was 10 rounds, a better group, but way worse ES and SD.

I definitely get the larger group size will make the data increasingly ‘worse’. Just trying to find the right load so I can stop load developing and start cranking out a few hundred of these. To be fair, an inch or less is perfectly fine for me.
It’s all Norma brass that came as loaded factory ammo that I shot in this rifle. So I guess it’s once fired?Yeah none of that data looks too crazy to me, is this on new brass?
Hell yeah. Killer set up tooPrepped 600 pieces of new Alpha 25 CM brass. Can't wait to start shooting this thing.
Gotcha. Not sure how much it actually helps but I do run my brass over an expander during sizing, and use graphite lube before seating. Regardless, if you're getting 1" or less 10 shot groups at 100, and nothing seems wonky when validating at distance, roll on little doggy.It’s all Norma brass that came as loaded factory ammo that I shot in this rifle.
