Thread: 7mm Rem Mag, where do I start?

As Per Gibo - But I went with IMR 7828 in mine and have been using federal brass like your self and some Norma. The Norma is streets ahead as the federal is much softer and thicker it seems to me.

When using The Federals after first shot from the box they are as dirty as hell, make sure you giv'em to someone for a good ultrasound clean and tumble - (Thanks Mike S!) I also found it useful to buy a Lyman large pocket primer cleaner to to make sure the new primers seat nicely in the pockets and flat with the bases. Was using Winchester magnum primers but changed to Federal match magnum primers after a few people had had issues with them causing issues with their bolt face. Supposedly there wasa faulty batch out there but I never did get eh lot numbers.

My loads I usually start at mid range and go up in .4 or .5 increments until you find a sweet spot based then do jumps of .2 to nail it. For me it was 63.3gr I think??? tested at 200m as 100m can have some diferences further out particularly with longer range and the accuracy can be different for larger calibres - so you need to check it at distance too.

I also use a 140gr Barnes TSX in Norma brass for close stuff and this has the same POI as my 162 Amax's almost exactly... So Barnes first in the Mag for a close up popped out in front of you shot, and Amax for distance shots. Mainly due to there being stories of the Amax blowing up on short distance targets around the place (not that I've experienced this myself).

Good luck it's a great round to play with...
