7mm Remington Magnum
While I initially did not include the 7mm Rem Mag in my ammo section it actually does have
a sniper history, primarily with the US Secret Service. They used the 7mm Rem Mag for a good
number of years using ammo loaded by HSM. The Secret Service eventually migrated to the
300 Win Mag and since then the 7mm has really only been minimally used in the snipng
community though it is a favorite of hunters and even some competitors.
One of the reasons the 7mm has not gained wide acceptance as a sniping round is because it
is seen that anything the 7mm can do, the .300 Win Mag can do as well or better. The 7mm
doesn't kick as much
but it shoots lighter bullets than the .300, though some of them have very high BC's which
allows it to do well at longer ranges. With the right ammo, the 0-1000 meter ballistics
are VERY impressive and the 7mm is easily capable of 1000 meter shooting, but it falls short
of the .300 in most regards while significantly outpacing the .308 (Which really shouldn't
surprise anyone). The Remington 700P was available for a while chambered in the 7mm Rem Mag,
but beyond that there are not a lot of sniper rifle options available that are not
custom built rifles.
Luckily HSM still loads the excellent 7mm 168gr match load that the Secret Service used
and it is available for purchase as is a 168gr Berger and 162gr Amax load which both
will rival the A191 300 WM load.
Recommendation:The 7mm is recommended for military applications out to 1000+ meters.
But keep in mind she kicks more than the .308 and is harder on barrels, but is a nice compromise
between the 308 and 300 Win Mag. Because the 7mm shoots the lighter bullets at higher velocities, it is better
suited to the law enforcment arena than the .300. But there is still a lot of power there, and
you'll NEED to watch the over penetration issue.
Military Applications
Note: The HSM 168gr Match King load was choosen for my military application load because it
uses the approved for combat Sierra Match King bullet and has really nice long range ballistics.

Law Enforcement Applications
Note: I have chosen the HSM 162gr AMAX Match round for is fantastic BC, very good accuracy and
it has rapid expansion and hopefully minimal penetration.
