Well an airplane ticket is cheaper than building a gun. Especially the wrong gun. If your interested, i will email you pictures of what we can do from
my front yard. No bs just in fact what we do and why i have the opinions i have. You pick the gun and shoot it at what ever distance you want out to 2 miles.
I can (guarantee) you that on many days you wont even see the bullet hits at 1500 yds with even the 30 cals let alone 6.5s or 7mms.
So forget shooting at 1500 yds with what your talking about doing. Id either be selling or sitting on the action and sticking with the 308.
Can you believe 50 years ago the 6.5 was the hottest long range cartridge on the planet? Thats simply because no good bullets existed for any others.
But when that changed, guess what? Guys rebarreled about as fast as rats leave a sinking ship.
