Load development

[Weatherby Fan]

Very few rifles will shoot 1/4 moa out of the box, no matter how much load development is done.

WF, if you want to talk about "specialized" shooting and load development, where cost isn't an issue then fly at it.

I've done the extreme accuracy thing and it's "expensive" to say the least.

Depending on what you're shooting at, it's also all done from the bench with often massive rifles. Not always huge rifles, but mostly.

I believe, the OP was referring to regular, off the shelf or maybe even custom rifles, meant for carrying in the field for practical hunting purposes.

Going off on a long range tangent to answer his question doesn't help.

The one thing which came from that video, which is very important, no matter which rifle you're shooting is the reference to Extreme Spreads being related to Combustion. That is a basic truth in any accurate load and why folks purchasing commercial loads are often surprised in a negative fashion.

Neck tension in such rifles is controlled in three ways, the first is the reamer used to cut the chamber. The next is to measure the bullet diameter, neck wall thickness and the neck diameter of the chamber, figure out how much clearance you desire, turn the neck, on a mandrel to achieve that clearance and set up a sizing die with interchangeable neck bushings to custom size your necks to your rifle. Trimming to consistent lengths helps a bit.

Some folks swear uniform neck diameters from cartridge to cartridge makes a huge difference. Maybe, in some rifles with tight chambers.

Maybe I missed the OP's question? I went back and looked but I don't see anything about "extreme accuracy" or competitive accuracy.

Many bullets aren't constructed well enough to be capable of such accuracy extremes, no matter how good the harmonics or lack of wear, bedding, etc.

It wasn't until the Juenke Gage was developed to electronically measure jacket thicknesses for consistency from bullet to bullet as well as all the way around its circumference that bullet manufacturers started developing manufacturing techniques which would repeatably produce consistent bullet jackets and cores, that such accuracy became doable. Those looking for such accuracy, pay for it in many ways.

Shooting a lot isn't a bad thing. Shooting a lot, under the conditions you're using the rifle for is a good thing.

no bartell never mentioned anything about “specialized” reloading process,

He just asked what method do you use with the accompanying list

You are correct very few factory rifles out of the box rifles will or can shoot 1/4"

I really don’t see anything in my posts about specialized reloading, extreme accuracy ? with that being said I strive for very good consistent accurate loads, I find consistent brass prep, neck tension, consistent powder charges and of course a bullet your barrel likes really helps.

Again everytime I reload I’m looking for the best possible accuracy out of my hunting rifle,
I will say that most every rifle I develop loads for has a custom barrel so that probably helps overall accuracy, the other thing as handloaders these days is the excellent components and endless information thats readily available certainly helps.

But believe me I’m not that experienced when it comes to handloading, I’m learning all the time, hand loading has evolved greatly just in the last few years and I really try to keep up learning and evolving in the process.

the OP of this thread is probably one of the most experienced and knowledgeable hand loaders I know of whom I’ve asked for advice many times, but I don’t always do things his way either.

The reason I posted that Cortina video above is he really simplifies things especially when it comes to consistency, my thought is I want the best possible accuracy out of my hunting rifle or target rifles but mainly hunting rifles for me so why not follow the lead or take advice on their PROCESS from the best shooters in the world
Cortina is just one of many,

So what is your method and what shooting discipline are your reloading for?

So what is your method and what shooting discipline are your reloading for?

The "Reloading All Day" Method and Theory by a Actual ballistician. Works great for any discipline.

Highly recommend it. You can see tons of Evidence of it working (100 Round Samples of SUB 10fps STD Dev) and if yoh know what that means from Litz's writing you know how impressive that actually is

And none of its really that far out there. People want there to be a "magic load" with this stuff, but as Dr Mann Even studied and published in 1909, it's not that complicated.

Do you mean the method of researching the most appropriate powder for your cartridge, bullet and overall length and then testing to determine the validity of your findings? Isn't that what this is all about and without paying $400 for a "course"? Being able to utilize a resource like Gordons Reloading tool or Quickload is relatively new and many people don't know about it, use it, or use it incorrectly. There is an old adage, "There are 20 steps in my reloading process but only 10 really matter, I just don't know which 10." With the increased number of cartridge designs and components, not all of which are readily available in GRT or necessarily even accurate, individual testing and experimentation is always required and following a recommended process to determine that is the best way.

All top shooters prefer as close to max case fill as possible. Do you know if that guy have any videos on positive compensation? I’m going to ask on another forum, what 20 round string winning matches, what the SD was for those 20 rounds.
