I just bought a DTA SRS A1 and want to put a 7mm rem mag on it

[Coomie]

Hi,

If I want to make a custom barrel for a DTA SRS in 7mm rem mag how do I know which DTA SRS bolt it will need? I asked someone and they told me they thought it would use a 300 win mag bolt but I wan't sure how one is suppose to know this?

Thanks,

You will need a magnum bolt face.
