Thanks. With the components and loads set for the first range session, what if things don't work out, what do you start adjusting first, second, etc. For instance would you stick with your first choice load and adjust the distance from the lands first or would you adjust powder charge, etc. edge.

Don't work out?? Hmmm.
Well... if you are going for "Longe Range Hunting", I would assume that when you take the gun out of the box, the first thing you do is take it apart, adjust the trigger to ~2-ish pounds, and epoxy bed the action and float the barrel.
That being said...
I guess if you are an elk or deer hunter, then you try another bullet, cuz there are so many of them out there... but there is a limit as to how many bullets you can test.
Since this IS "Long Range Hunting", one would presume that the cartridges are large for the bore size, ergo, magnums, or cartridges that burn optimum powders of 4350 and slower class.
Also, that the barrels will not be feather weight.
So a medium or heavy barrel that is made reasonably well, should show it's possibilities pretty quick.
So going through the whole catalogue of bullets would be fruitless, cuz you wouldn't have a throat left.
You have to make some decisions up front.
If the gun is off the rack, then you can have an excellent barrel, or a turd.
A good barrel should be showing good groups right off with reasonable loads.
For example, with a 300WM, and a quality 180 - 200 grain bullet, if you can't get 3/4" or better with H-4350 and/or H-4831 within 60-80 rounds, you have a dog-a-roo, and don't waste any more time with it!!
Playing around with every 180 bullet you can buy ain't gonna change things. You might "get lucky" and find something after 400 rounds (and $300 worth of components)... but even then, that "good group" might just disappear the next go-around.

I set the bullets to touch the rifling - if the magazine isn't long enough, I either lengthen the magazine, or load single rounds - after all, at 700 yds you ain't gonna need (or get) a quick second shot.
With bullets seated to touch, and decent powder/bullet weight combinations, if I couldn't see good grouping possibilities in 100 rounds, I would replace the barrel with a custom barrel from a good maker.

"I think"... that putting together a long range hunting rifle is a project that should be planed and thought out.
I don't think you get a successful long range rifle by grabbing the first magnum on sale at Wally-world, with the generic Chin-lee 3x9 scope that he threw in to sweeten the deal.
I think these rifles need to be thought out in advance... balanced as a unit.
You pick the caliber and optics and rifle to fit your goals.
For example...
I have a need for a very long range coyote/feral dog rifle. A member of my family has a problem with them on her pedigreed cattle spread. A lost calf is the down payment to a nice car!
I used to use a 300 WM with 178 A-Max's, but I found out that they didn't open up very fast, and often bounced around the north 40.
So I am putting together a new 1,000 yd coyote/feral dog rifle in .264 Win Mag, so I can use real fragile varmint bullets.
I had considered building from scratch, but the cost wasn't worth it, so I bought a Remington Sendero-II, after two friends said that they were using the Sendero-II's for 1,000 yd "F" class match shooting, "out of the box", with trigger adjustments.
I chose the rifle and scope together with one purpose, so everything was picked before the rifle was bought.
Here's the process.
1 - Caliber - I needed to have a caliber that had the most possible range, with proven fragile "varmint" bullets... which was why I was giving up on the 300 WM. The caliber/bullet had to have enough energy at ~1,000yds to completely wreck a 70 pound feral dog with an attitude, even with a less than optimal hit.
Simply going up the list of varmint bullets came to .264/6.5mm. Bore sizes larger than that had poor choices in varmint bullets, with poor BC's, which meant poor wind characteristics. The bullet was the 95 gr V-Max which has a very good BC and excellent (and proven) "explosive" effects.
That was just about IT for bullets.
Then the scope... the targets in this case are furtive, and don't stand out in a meadow waiting for you to get your collective poo-poo together. So fast ranging and very fast shooting were needed. When I was using other guns in the past, the time waisted in dialing the elevation cost me many targets... and also many were lost because I was a "whole turn off" on the elevation turret.
So I chose the Leupold MK4-M3 scope that had ranging cams (BDC), and one turn from 100 to 1200yds. If I dialed it, it would be there, RIGHT NOW!
I had used this scope in 1,000 yd field competitions before and it does work well, and fast.
I made these decisions BEFORE I chose and bought the rifle.
On the recommendations of the Sendero's, I was a little bit cautious, cuz I have had a few Remington that were turds in the past. I ordered it with the understanding that I could refuse it "for cause"!
When it came in last fall, I looked it over real hard, and it was probably the nicest/smoothest Remington I have seen in 20 years - action was like glass, barrel was centered in the channel. I ran a tight patch through the barrel, and it was consistently smooth, with no loose spots. No tool marks, or rough spots anywhere. Not a perfect test, but a good start.
Working up the loads... With a cartridge like the 264WM, you don't want to spend months looking for a load, cuz you won't have any barrel life left.
So I picked two powders that looked good - H-4350, and H-4831. I picked these powders because they are temperature stable, and clean burning. The H-4350 is a bit fast to be "optimal", and the H-4831 is optimal in burning rate, giving 100-150 fps more velocity.
But I have found that powders on the fast side generally give better groups, and I was looking for the best accuracy.
Then I loaded 2 rounds of each powder weight, in one grain steps.
Now two rounds don't prove a great load... but the DO prove a badd load, plus you can find the max loads and upper pressure limits at the same time.
If two rounds are touching, this can be a great load, or just two shots out of a five shot group that was badd... but if the two shots are 1.3" apart, you KNOW this is a sucky load, and you don't waste time with testing it further.
Then you pick the best two shot groups, and test them with 5 shot groups. It's easy.
If I hadn't found a good load in ~100-120 rounds, I would have sent it out for a new barrel.
That's how I do it... I'm sure that others do it differently.
On the Sendero... all the 2 shot groups were touching /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/smile.gif
