Re: Rifle build help
If your stw shoots good I think you have about as good as it gets for your purpose. I have five 7 stw's and three 300 ultramags. I would keep the good shooting stw and build a 300 ultramag. Then your good for about anything that walks. One of my 300 ultramags has a 1-14 twist 28" barrel for shooting light bullets and it is a lazer out to 700 or so yards. After that the low bc kills it in the wind. It shoots a 130 Barnes tsx right at 4000 fps and the 150 grain nosler etip with a .469 bc right at 3800 fps. It is a pleasure to shoot deer size critters at your 700 yard range estimate. Extremely flat shooter. But it is a specialized weapon and if you ever wanted to go 1000 yards or so it will not shoot the long, heavy high bc bullets.
Predictions are difficult, especially when they involve the future
