Ammo Inc 7mm Rem Mag 139gr SST – Swift 20 Round Hunt Long Range Box

Description

Ammo Inc 7mm Rem Mag 139gr SST is the Hunt Long Range half of a pair we stock at the same bullet weight. A 139 grain Hornady Super Shock Tip leaving at 3,150 feet per second, printed on the box, twenty rounds on reloadable brass. The tip is the whole reason to choose it.

Tipped Versus Plain at the Same Weight

We carry two 139 grain 7mm Remington Magnum loads from this maker and the difference is construction rather than weight. Our 139 grain Hunt SP uses a plain Hornady InterLock soft point at a listed 3,200 fps. This one uses the polymer tipped SST at 3,150 fps.

Fifty feet per second is nothing, so Ammo Inc 7mm Rem Mag 139gr SST is not about speed. The polymer tip is the meaningful difference. It raises the ballistic coefficient so the bullet sheds velocity and drifts in wind noticeably less past three hundred yards, and it drives back into the core on impact to start expansion immediately. If your shots are long and open, Ammo Inc 7mm Rem Mag 139gr SST is the one to buy.

The flip side is that a tipped bullet at over 3,000 fps opens hard up close. On a broadside shoulder shot at forty yards it will cost you more meat than the plain soft point would. Neither load is better in the abstract; they suit different country.

Ammo Inc 7mm Rem Mag 139gr SST Specifications

Figures for Ammo Inc 7mm Rem Mag 139gr SST are printed on the box by Ammo Inc and measured from a test barrel. A 24 inch hunting rifle will land near 3,150 fps and a 22 inch barrel somewhat under, which matters if you intend to shoot at the distances this load is built for.

Check the barrel stamp before ordering Ammo Inc 7mm Rem Mag 139gr SST. This product is catalogued by distributors simply as 7MM, and that name covers 7mm-08 Remington, 7×57 Mauser, 7mm PRC and 7mm Remington Magnum, none of which interchange. The box says 7mm Rem Mag, and that is what this is.

At 139 grains this is a deer and antelope load. For elk most hunters would rather have 160 or 175 grains of a heavier or bonded bullet, because a light for calibre cup and core bullet at this speed is working hard when it meets heavy bone.

Shooting at the Distances This Load Is Built For

Set your limit for Ammo Inc 7mm Rem Mag 139gr SST from field positions. A high BC bullet at 3,150 fps carries enough energy well past four hundred yards, but energy is never the constraint. Wind reading and how steadily you can hold off sticks or prone are. Shoot at distance from the positions you actually hunt from before deciding what your maximum is.

Confirm zero with this exact box. The tipped and untipped 139 grain loads will not print to the same place, and if you keep both in the cabinet you need to know which one the rifle is set for. Three rounds on paper each season settles it.

Wind matters more than drop past three hundred yards. Drop is predictable and you can dial it; wind is a judgement call every time. The higher ballistic coefficient here reduces drift but does not remove it, and practising in wind is the only thing that improves that skill.

Practise the recoil away from the bench. A 7mm magnum will teach a flinch over a long session. Our A-Zoom 7mm Rem Mag snap caps let you drill bolt work and trigger press at home, which is where that gets corrected.

Keep the brass from every box of Ammo Inc 7mm Rem Mag 139gr SST. Belted magnum cases reload well, and once fired in your chamber they should be headspaced on the shoulder rather than the belt for longer case life and better consistency. An ammo box in a comparable case family keeps fired brass apart from loaded rounds.

Ammo Inc 7mm Rem Mag 139gr SST suits open country deer hunting where the shot may be long and the wind is the problem. If your hunting is close and in timber, buy the plain soft point version instead and keep more meat. Ships from our licensed inventory in Collegeville, Pennsylvania, with adult signature required on delivery.

On supply, Ammo Inc produces in batches and the magnum hunting calibres clear shelves through September and October. If a lot groups well in your rifle, buy enough of that lot for sighting in and the season together, because the next run may print to a slightly different place.

Stored somewhere cool and dry it will keep for decades. Heat cycling in a truck through a summer is the one thing worth avoiding.
