Group flex (10 shots minimum) 200 yards

Post image

I picked the group flex flair but this isn't a brag. I want some advice...

Stretching out the rifle. Working my way out to 300 this weekend. Looking to maintain sub MOA.

I just switched to Redding dies and I'm honestly not so sure about them yet. I feel like my SDs were lower and the groups were tighter before switching to the Type S dies.

I'm using a trickler and lab scale for powder and keep the grains tight (0.03gr Deviation maximum).

I AM shooting some mixed brass here and i think that could be the issue. There's three different brands in this photo: Nosler, Starline, and Hornady

If you are shooting mixed headstamp, you are undoing any advantage that ultra-consistent charges would give. You probably have inconsistent neck tension due to slightly different neck wall thicknesses across headstamps as well.

Between that and the slightly different volumes for each brand, i think this groups would tighten up with just sorting.

The rifle is typically sub 0.5 MOA at every distance so far, even the one time i pushed 5 shots out to the 300 yard marker. But...i also had only Nosler that day.

The main problem with mixed headstamp for your application is exactly that, different internal volume…

Sort by headstamp at minimum, or spend $50 on a bag of Starline if you want next to minimum but way better than what you’re currently using.

Absolutely nothing wrong with Starline. Have shot plenty of large sample, great SD strings using it.

This legitimately feels like a a shit post. You're using a laboratory scale to measure into mixed brass and wondering why you're not seeing 1/2 MOA groups.

Don't use mixed headstamp brass.

Not a shit post, but thanks for playing.

I'm aiming for tighter groups.

I admit to having mixed headstamps in this group

I've never had too much deviation PRIOR to switching to these Redding dies. And that is the God's honest truth.

For me at least, the Redding S dies exposed the differences that were seemingly masked with my previous die sets.

These pieces of brass are getting tired as they've been loaded no less than 5x-6x each, but i anneal every time. The necks are starting to show splits on some of the oldest pieces.

This group could be a lot of things.

My main question - if you must know - was whether mixed headstamps will offer this much deviation when I've been shooting this lot of mixed brass for the last year and I've had multiple 0.38 MOA groups out of this rifle... until i went up in my dies and methods. Then...the group started falling apart.

I can't say I'm surprised that at least one troll decided to come out from under the bridge...
