Who does this method part 2

[Outdoor]

First, I want to thank EVERYONE who jumped in part one. Always something to learn and I am extremely grateful for your knowledge. Does anyone ever get together over coffee to discuss reloading? I’m in Gettysburg, PA

As a shooter who just reloads because I enjoy it, I get better results than factory.... and the bonus is availability and money saved. Lastly you understand better why the projectile does what it does.

>>> NOW what should be done first and why:

Do you develop the load first then work on distance from lands? Does it matter?

reloading and money saved should NOT be used in the same sentence

The distance to the lands is nothing more than a starting point. Once you've found a starting point, the distance to the lands is irrelevant and the focus is on seating depth. That is . . . when we're loading off the lands.

If one is load to touch or jam, then keeping up with throat erosion is needed and "chasing the lands" is what I'd say . . . appropriate.

I like how they now call that the Deepcreek method. Alex Wheeler was the first I heard doing it this way, he did compete at Deepcreek maybe that’s why.

If my magazine or lands will allow it,
I always like to find seating depth first before wringing out the most accuracy from the load.
I have seen a difference of .010" seat depth make a HUGE difference in grouping
So feel it a waste of components testing without finding a good seating depth FIRST.
-------------
Some guys tune with powder charge and with things such as an AR-15, youre limited to Mag Length, so with that powder charge is really the only other way to tine unless you keep seating the bullet deeper a little at a time finding a node that way, which can be done.
-------------
In any cartridge I kind of want a certain velocity so load a safe load to approx that velocity then tune in seating depth.
Afterward I tune in the powder charge for consistency
------------
Then revisit seating depth again and fine tune to make sure I am not slightly out of tune.
------------
I find using seating depth the quickest way to at least.... get a very accurate load,
Sometimes within 20 rounds... if the powder burn rate matches the particular bullet well.
------------
The way I view it is like this
Your barrel will vibrate pretty much at the same frequency no matter how hard or soft the powder smacks it
---Take a tuning fork, lightly tap it, or smack it with a hammer hard.
Wont matter, it will still vibrate at one frequency.
---------------
Therefore even if I use 2 different powders, as long as I am driving the bullet the same velocity
I can retain and use the same seating depth for both powders (retain same exit timing of bullet)

I think there’s a difference tuning a machine gun built for minute of chest and a benchrest rifle.

If you use the search function here, you could spend days researching the subject.

I was covering all bases with a comparison also to guns that have a limited OAL to play with
It's not just AR type platforms
Even a 7/08 built on a short action but using newer High BC bullets will be limited to Mag Length as well just like an AR will be
And I can assure you, todays AR's are much better than minute of chest and are not machine guns
that is M-16.
Try 10 shot groups with all bullets holes touching, done with powder charge & leaving seat depth alone.
---------------------------------------------------
a guy "CAN" tune with powder charge only
but is more beneficial initially to be done with seating depth first.
---------------------------------------------------
The OP specififed he is a shooter who just reloads because he enjoys it,
not a benchrester hence why I covered a few simple bases for his experimenting

I don’t have that issue with my 7-08 and any gun that puts another round in it automatically is a machine gun as far as I’m concerned but to each his own. I can make a ar15 fully auto before you could finish smoking a cigarette. Have a wonderful day.
