I think you need to watch the Furman videos on Long Range OnlyThe outdoor life article didn't make much sense to me- he was looking at charge weight to dial in his accuracy? I thought the point of charge weight was to get your SD as low as possible… how can he think that single digit SD won't shoot better than say 50 SD at 1000 yards? And aren't small sample sizes the most valid thing to track.. if I run threw 30 rounds in 10 minutes I am going to have a very hot barrel and a lot of heat distortion in my scope.
LL, that's also what I recommended in #8.So one guy posted a video that he found no difference in accuracy with seating depth changes. So the reality of statistics is that is just one data point. You would need at least 30 more people to replicate the results to see any trend. I suggest you read Bryan Litz's books if you want to nerd out.

Nah, I get what you were saying. The joke is on you.
I am new (since 2019) to the long range shooting community and admittedly my experience is limited. I have been frustrated with all the voices claiming their methods are "how it should be done". I am not inferring that their methods don't work, what I am saying is that if so many different methods all produce the same results, accurate loads, then logically not all of the processes in the various methods are as significant as believed. In other words, the methods may work, but not for the reasons we believe. My goal is, through applying the scientific method, to sort out what actually makes a difference in the reloading process and what is just the deeply held dogma of the community.
I deeply appreciate and respect the experience and knowledge of those in this community, and their willingness to share it. I know that their methods work and produce accurate results, all I am trying to do is figure out why. After recently stumbling across the following information, I have radically changed my thoughts on how I approach reloading. I thought the community might benefit from the information they proffer.
I am looking to have an honest discussion about the information linked below and to hear your opinions, many with infinitely more experience and knowledge than I. If you take the time to review either of them, I would welcome your insight, obviously your have been doing this a lot longer than I.
Rifle Nodes: How You’ve Been Wasting Your Time and Money on Load Development

Yup....that's exactly what I wrote.This! Unless someone posting here has access to the Hornady, Federal etc test facilities there is no way to gather empirical data, there are to many variables. Think for a second what Hornady has at hand. An indoor, environmentally controlled facility, using rail guns. With a Doppler radar system that costs a couple hundred k. With precision tools to build their test ammunition and the ability to do as much testing as they want. My guess is no one here has this. Even so look at Hornady's variables. Every barrel is different, the way every barrel was cleaned is different, barrel life is different, different technicians running the equipment etc. Even with all of this their product is of middling quality. Granted they are tuning loads to no specific rifles and mass producing the ammunition.
To me this why an individual can run a 3 or 5 shot OCW at 100 yards, get a sense of what his rifle likes. Load a bigger sample size, test that, adjust if necessary, test at long distance, adjust if necessary. Result a load that shots great in your specific rifle. Statistically valid empirical evidence? Absolutely not. Does it work? Absolutely yes. That's all I care about!
Link? He is just talking about running ladder tests in the forums I read, I know how to run a ladder test. Every load I shoot I shoot across my chrono during load development. My point is that during my load development I shrink my SD from 35 to 4.6 and my group size from 1.5 moa to .25 MOA and I guess it's not statistically relevant? It seems to be relevant to me but maybe I have an overactive imagination.I think you need to watch the Furman videos on Long Range Only
I meant your powder load. Are you over the published recommendation, in the middle, low, etc?The 22-250's are 3275fps from 22" and 3300 from 24".
The 270's are 3030 fps from 22".

"Science" is testable, repeatable, verifiable. I don't remember anything about the why. Nevertheless, I have no idea why one powder doesn't "work" and switching to another does. I guess if we knew why, we could save a bunch of components and time.
