I've got a Remington 700 Stainless Mountain rifle in .243 Win. It shoots 1" groups at 100 yards. However, because the barrel is thinner than a standard rifles making it very light, you need to let the barrel cool between shots. If you don't, you'll get the results the others described above (less accurate). Its really the first shot that counts. From a cold barrel, I can shoot 3 shots before the barrel begins to heat.

When hiking deep - this is my favorite rifle at 7lbs with a scope
