RE: 7MM Rem Mag Ammo
 

Accuracy considerations aside, most 7mm R Mag. factory ammo is badly underloaded. For example, I can get over 3000 FPS from 175-grain handloads, while the factory is claiming 2860 which may or may not be their actual MV. Why shoot a 7mag when it only performs as well as the 280 REM does with less powder?

My Savage M110 7mm shoots everything well (under 1 MOA). The Winchester Supreme 150 grain BST shoot super tight groups (sub-MOA past 300 yards) in that rifle and Federal Premium 160 grain Nosler Partitions only slightly larger groups (and absolutely devestating on everything I have shot with it).

IMO, the 7mm is generally a very accurate cartridge regardless as to the factory ammo maker. Find a round that your rifle likes, you are comfortable with, and can readily purchase.

Here is a bullet weight/barrel twist chart http://www.riflebarrels.com/products...wist_rates.htm that is a good place to start. Try different brands in the correct weight range for your twist until you pick a winner. My old Savage 7 mag always liked Federal.

About all I am doing is echoing what others have already posted. Any of the factory loads using any of the many different controlled expasion bullets will do the job. The 7 mm Rem. Mag. is a fine choice for a huting rifle. Not my favorite ... but.

Truth is that every rifle will "like" a certain load better than any other load.The proof is in the consistency of tight groups.I worked up a load for a 6.5x55 Se I have. Some of what I worked up grouped as poorly as almost 3 MOA. The "sweet" combo groups under 1 MOA. That is not uncommon.

You stated that the Rem. CoreLokt ammo that you have groups well and you have had good results on game, including moose. Based upon that info, I see no reason to change. Take a look at the Lot # of the ammo as another mentioned.It should be printed on the box. If you can locate more ammmo in this same Lot#, then the odds are that the loading will be almost identical and the ammo will group more or less the same round to round.

how about some of these...?

Give the Federal Fusion a try. It seems to be accurate in quite a few different rifles, and the bullets perform darn near as well as the Accubond. Cost a heckuva lot less, too.

Federal is offering 150gr and 175gr Fusion loads...these should cover just about anything you'd want to hunt with that rifle/cartridge combo.

Say you have had good luck with the core-lokts..... Then the core-lokts are the very best ammo out there! [:-]

I personally like the HornadyCustom SST 154gr. p/n 8062, works good in my ol' Remington 700.
