308, 223, 8mm, 270 realistic range of use...pt. II
Of your list, without getting into a new rifle I would say depending on condition the 8mm Mauser has an excellent chance of getting you accurately to 1k. {edit:} I shoot a 200 gr. SMK from my son's Rem 700 classic @ 1k with pretty good success. So the round is capable if not the older rifles. My VZ-24 re-chambered in 7x57 beats that regularly. However, it's been accurized at a very low cost all told (for a long range gun), of about $1200. Mind you a new Savage 12 w/precision action in either 6mmBR or 6-.284 costs less than that. Very accurate Remington 700's can be had for less than $1k.
Without changing anything, either the K31 or the .270 have a chance to go as long as what you say. Farther even if you have the patience. There are a lot of high BC bullets the K31 can shoot and even though there isn't a lot in the .270 Caliber, they do exist. For the .270 my choice would be Berger hunting VLD's. Although as nn stated in the last thread about this, Nosler does have excellent ballistics in the Ballistic tip and Accubond lines and Sierra actually makes very accurate target bullets for this caliber in a couple of different weights. The only problem with the .270 is no one has decided it sits right in the middle of the weight/small (optimal) diameter range to get heavy bullets with long noses....yet!
As for the 7.5 Swiss, it takes standard .308 Bullets and if you keep loads moderate (they don't like hot loads) you can push 175, 180 190 and 200 gr. SMK's, 168, and 178 A-max's from Hornady. Nosler has 155,168 and coming soon they will have 190 Custom Competitions. Berger has the full range as well from 155's -210. These are VLD's and fly extremely well from my K31. Remember two things with these rifles. One, they don't really take all that well to light bullets. Although some rifles do. And they don't take to hot loads. It isn't so much a matter of the action not being able to take it, it's just barrel harmonics. I typically push 175 gr. bullets out at around 2525 fps.
The last thing I can say about this is, if you start shooting long range, and get addicted to it, don't spend a lot of money modifying what you have. Shoot it. See how well you do considering the accuracy potential of what you are shooting. If you can get behind someones gun (with their permission of course) and see how well you can shoot behind a gun that is set up for 1k shooting and longer. That will really tell you how far you have to go and if you truly will ever get there. I hope you do.
-good luck
