20 Deg winter, oh wouldn’t that be nice. Winter for us is anywhere from 0 up.

Well Haha, going back to pre teams banter .... QLD , THE BEST STATE !

Depending on the range. Look for an upcoming post in this series soon.

I have been thinking of what I was going to write in here and had a few good ideas, but when I read Kieths reminder about making sure the shooter is not the weak link, that I decided to bring up some very important issues which very few people think about before they get into the fun technical tuning stuff we all (myself included) really get off on
The things I would like to discuss are.
1. The shooter. Their hold, their technique and their tactics
2. The range. Some ranges are much better than others for tuning on and it is not just the wind conditions there.
3. ETs. No, bare with me, it is not one of my well known rants against ETs. They are work great when they are working great.
4. Gear and mound set up.

Ive just got home from a hectic 13Hr shift so I wont go too much into these things in detail yet. Should they go in here, or in a separate series?

It'll be great to have you aboard Rod. I think separate threads would be best. How about starting with a Gear and Mound Setup 101?

Break it down step by step in here I reckon Rod - there's plenty of us interested in your thoughts/experiences regarding this.

I’m guessing this has to do with wind angular torque or wind shear at a Qld range ?
That will be a good thread to discuss, as it’s a very tuff range for especially when the wind comes from the left and the lower number targets . But till then !
It still is one of the best and the hardest. Anyway off topic !

assuming that your loading process is "tuned", it would seem that there are 2 main basic tuning tools to work with.
they are bullet relationship to rifling, and powder charge.
when both of these things come together in the best balance, the load is tuned to the rifle.
most people seem to start with powder charges, adjusting them until best accuracy can be obtained that way.
they keep seating depth the same, as it is better to only adjust 1 thing at a time.
they then go to adjusting relationship of bullet to lands by adjusting seating depth.
I will often try different seating depths while running in the barrel, to compare jump vs jam for a starting point.
common practice might be to start jammed hard, as pressures will reduce as coal becomes shorter.
max jam can be established by letting the camming power of the action seat a bullet as the bolt is closed.
I have often wondered if starting with seating depth or starting with powder charges is a better way to go.
if you are ladder testing, with increasing powder charges, the most accurate seating depth could offer some advantage.
guys test in different ways, and this might have some effect on how you tune.
if you do seating depth first, then powder charge second, it might pay to retest seating depth at the best powder charge.
and then of course you start on neck tension.
is the rifle still in tune?
what has happened with throat erosion while all of this was going on?
what is your velocity s.d.?
at this stage we have not yet thought about a barrel tuner.

[bruce moulds]

good point wal.
there are probably 3 main ones to try, but others can be better.
at what stage to you try them?

wal's primer post disappeared while I typed the above.

[Wal86]

After 39 posts no mention of the importance of primers and ignition?
basic 101?

Primers
seating depth
neck tension
- should all be worked out in the first 25 rnds of the breaking in process, bullet holes in paper (group shapes/and their shot order) are not random...

Another process that is overlooked is cleaning regime and consistency...

Just a thought,

[cheech]

I’m sure it doesn’t need to be said, but make sure you know how many fouling shots you need before embarking that golden group .

[bruce moulds]

yes, cleaning regime is very relevant to this subject, and can be connected with the fouling shots requirement.
