700 feed rails question.

[philipbrousseau]

does anyone know for sure that the feed rails in a Remington 700 in 7mm rem mag are the same as one in 300 Winchester mag? thinking about putting a 300 win mag barrel on it. thank you

They are the same. If you want to make it a rum or nosler, you’ll need to open it up around .010”
