Long range / long action

std7mag says:
For shooting out to 1000 yards, and ringing steel targets, I would stick with the 30-06.

For match shooting I would probably go towards something else.

Why would you pick the .30-06 when there are more accurate cartridges with longer barrel lives and easier to shoot with more precision? For example, the .308 Win's been doing that since the 1960's

What's the difference in size between steel plates and the high scoring rings of match targets at 1000 yards?

What's the greatest amount you want to miss your point of aim at 1000 yards?
 
"I think what MOBUCK is saying is that unless my skill is up to level it doesnt matter what the cartridge is in a target rifle"

Correct. Long actions have slightly more flex and stocks for long actions are less stiff BUT the difference will not be apparent until other factors are perfected.
 
The long action just a preference? Has nothing to do with the distance.
"...like the 6.5x55..." Not many match bullets in 6.5. 140's and 142's from Sierra. 140's only from Hornady. Kind of limits you.
Your 700ADL is a hunting rifle. Good place to start, but still a hunting rifle. Barrel is not up to extended target use.

Huh?

120 amax, 123 amax, 140 amax, 140 BTHP, all from Hornady
120, 130, and 140's from Berger
120, 130, 136, 140's from Lapua.
123 and 140's from Nosler
120, 123, 140, and 142's from Sierra

Plenty of match bullets available in 6.5mm...

Comparing two barrels of the same dimensons, one chrome moly and the other 416R stainless steel, for fundamental frequency; higher frequency is in the stiffer barrel:

Breech Fixed & Muzzle Free

bore area S= 0.0736 square inch
breech diameter A= 1.1 inch
reinforce large diameter B= 1.1 inch
reinforce small diameter C= 1 inch
muzzle diameter D= 0.7 inch

reinforce length AB= 2 inch
reinforce taper length BC= 2 inch
main taper length CD= 19 inch

total_length= 23 inch (1 inch in receiver, 24" OAL)

Type 416R Stainless Steel
total_mass = 3.646 lb
fundamental frequency = 75.33 Hz

Type 4140 Chrome Moly
total_mass = 3.620 lb
fundamental frequency = 74.7 Hz

That frequency and the amplitude the barrel wiggles will change with receiver, stock and sight weights as well as the distance the bore axis is above the center of the butt plate. The whole rifle weight has to be in the calulations; finite element software is needed to get the real numbers. Varmint Al's website has some examples.

While the barreled action's stiffness/rigidity numbers contribute about 2% to the rifle's accuracy, I think one should put their resources into the three things that contribute 75% to it. The barrel, the bolt and their fit are most important, are commonly the cause of poor rifle accuracy with the best ammo used.
