I'm thinking to give my 111 model upgrade, right now it has factory barrel, its great shooter and very light, but after 3 shots barrel heats up and group opens up. I primarily use this rifle for hunting deer, it didn't miss single one in 5 years I used it. During off-season I like to shoot it of the bench, but the thin light barrel limits number of shots. So I decided to replace its barrel with more heavy barrel, but most barrels I see chambered in 270 are factory contour.

Does anyone know who makes 270 WIN drop-ins in light varmint or varmint contour?
