Rifle Nodes - You’re Wasting Your Time

Most load development practices of 10 years ago are basically nonsense based on 3 shot groups and witchcraft. Equally in my view barrel tuners are total waste of time. Most people refuse to accept the maths but hey ho.
Having said that my experience is bullet length in my case did affect velocity. And a making my over all length 2mm longer (allowed a better powder burn? I was getting unburnt powder left in the barrel) resulted in a 70fps consistent increase in speed. No real increase in accuracy.

A quick Google AI on modern load development methods is worthwhile.
However it also states that OCW method is still valid. I have a new rifle to load develop shortly, and do a velocity ladder, pick a flat spot, or a target velocity, verify the suitability/SD with a 10-15 shot session over the chrono, then play with seating a la Berger Hybrid seating test. I will be shooting informal 600yd F open with it, so I want the best from it. If this isn't productive, I'll take it as a lesson, and go to OCW.
For a hunting rifle, most of this is likely a waste of component and barrel life, but many of us still want to see what our rifles are capable of, it's the real purpose of reloading, because it sure ain't economy.

Read the article, Malcolm. It says you’re wasting your time and money.
 
I think the other myth is using larger samples makes reloading more expensive and time consuming. However as the article points out it will actually save on bullets, powder, primers and time. Nowadays I think more about the terminal performance and speed I need to allow the bullet to properly deform at the range I shoot up to… ie I want plus 2000fps at say 350m or supersonic at a 1000m for targets and work back to the required load.

I have done, it's not a new concept to me.
You don't shoot anything but deer, so it definitely applies to you. Lots of articles say lots of things, it doesn't mean they are 100% correct.

Partially true. I was smacking gongs at 700m a couple of weeks ago and it was a lot of fun.
 
Smacking gongs, pretty much what PRS shooters do. They'll still identify a target velocity and verify that SD is single digits, it's still load development and still requires throwing a few rounds over the chrono. I doubt you'll find any F class or bench rest shooters that have changed their ways due to this article since it appeared, and as I recall was discussed on here a couple years ago.
Barrel harmonics are still real, it's just that they really don't matter much to anyone shooting deer at sensible distance.

I agree many people don’t change their practices or procedures but it’s pretty much head in the sand stuff. I don’t believe the maths is wrong and if you do then your are consciously ignoring a fact based world view. Which is fine but a little strange.
 
There was a lot of discussion on this topic lead by @Mungo. Mungo is a very eminent biologist who really understands statistics, and use of statistics in research. His view that small group sizes and small number of total groups are really very insignificant in number.

In military procurement of ammo, specifications are based on a large sample number of rounds - I think 100 or so, with a percentage of that number have to fall with a certain distance of an aiming point.
 
"Your wasting time and money....."

What are you doing shooting larger sample sizes?

If its time and money why shoot period?
Find a hobby that you dont mind spending money and time on ?🤷‍♂️

Your not going to find out what s rifle likes without firing it

Folk are all different and do things different ways ..... this going to end up like religion where one person tells another what they are doing is wrong and what they do is right?
