Almost all snipers in the US military today are still using a some Remington 700.

The Mk13 which is expected to replace the Marine's scout snipers M40 is 700-pattern, just not built by Remington.

You're going to be right soon, just not yet.

Likewise, "The Military" is still using Rem 870 and Mossberg 500 shotguns. The "other military" that is, the IRS, Deptartments of Interior, Energy, Education, and everything else; their SWAT teams all use the Rem 700 and 870.
