Re: steping up - hopefully
Blazer man3, consider the following. From what you have said, your budget available is $2000 to 2500 for just the rifle/scope. That is a lot of money.
First off if int in the 270 cal, then go with the 270 win. That is right, the good old fashion 270. For the ranges you are shooting, the extra 200fps is just not that important. Go 150gr which will be plenty out to 400yds.
If willing to look at another cal, then go 7mm in factory, 6.5/7mm in custom. For the best factory cal in 7mm, the 7Rem mag is hard to beat. With 162/168gr bullets, you will have everything you need to anchor game near and far. The newer short magnums are also good but new rifles cost so much more.
If rebarrelling, then the 6.5Gibbs, or 280AI/Gibbs are excellent choices. I don't recommend the 30cal simply because the BC are not that high for the recoil and bullet weights commonly used. If you are building a big stick and can use 200 to 240 gr bullets, then go 30cal and hammer things way out there.
I shoot a 30Gibbs and 165gr SST. An excellent small 30 magnum but the bullet gets tossed around at long range in the wind. The 6.5 and 7mm bullets will fly better and hit just as hard (retained vel) at the ranges you want. Cheaper components too. I will be looking at going 7mm when this barrel burns out.
As to rifles, I would look at Tikka T3, savage, howa/Wby vanguard, used rem/win. used rifles are usually in excellent condition. If considering rebarreling, the a used Rem or even Mauser is an excellent choice. Remember accuracy has more to do with the barrel, trigger, stock and load then the action.
For scopes, look at the new 30mm Nikon monarch golds, Bausch&Lomb (now Bushnell) Elite 4000/4200 scopes. Will be substantially cheaper and just as good in the low light. Burris sig and black diamond line may also have good low light performance.
You should be able to get into a great shooting rig for around $1000 to 1200 w/scope. That will leave lots for reloading gear and practise. You may also want to pick up a Leica 800rangefinder for around $300 too. A good set of binos are essential. (Nikon Monarch around $300).
I would recommend against buying a new unknown product especially if that expensive. Most production rifles shoot about the same with a little tuning and good loads. Go used or a less expensive brand.
If willing to spend $1200 on a factory gun, you can buy a used rifle, rebarrel and have a shooter for less money.
