I am new to reloading, and my first gun to reload will be the 7mm remington mag. i hear this can be a finiky round to reload. I will be using this gun for white tail, with the longest shot +/- 300 yds. thanks in advance for the info.

Hi jib021983 & welcome to AR!! I see this is your first post & also see you're getting into reloading. Do you have any questions about reloading for this round in particular?? Do you have a reloading press, dies, powder and if so what type, bullets and if so what weight?? Have you tried reloading yet, or are you looking for tips/tricks on reloading for 7mm rem mag??

Welcome to AR JLB!Your question is a very broad one mate, If you're a complete neophyte then the very best idea is to ask at your local gunshop if there is an experienced reloader in your area that wouldn't mind you looking over his shoulder for a few lessons in exchange for coffee and doughnuts.

Nothing beat having a person there to take you through the process a few times.

If you're on your own then you need to get hold of two or three good manuals, I like the Speer, Hogdon and Vihtavouri personally, and have a good watch of this guy's: Ammosmith video's for beginners.

Which other calibres do you shoot?

I've loaded for several 7mags over a lot of years and found them as straight forward to load for as any other bottle neck cartridge. I don't know where you're at regarding reloading but I'd suggest, even with a mentor, that you get a couple of good load books, Lyman and Hornady come to mind, and read the intro to reloading section a couple of times before trying your skills or buying your kit.

If I remember correctly, when I was looking at the RCBS web site a few days ago they have a video on reloading that you can click on and watch.

I've loaded 7mm Rem Mag, 7mm Weatherby, , .276 Dubiel and .275 H & H off and on for 40 years or so. To me they are straight forward, folow published manuel loads and forget the fast powders if any are listed.

Good luck, enjoy the ride!

You can never have too many reloading manuals. It is always good to cross reference and compare loads. If you don't have a Lyman Manual, get one. Not only does it have data you need for loads, it has a lot of information about reloading.

As has been stated, get the Lyman manual. It covers the reloading process beginning to end and is a great place to start reading up. I've only been reloading for about 5 years now and I still go back and reread my Lyman manual just to keep things straight in my head.

Ken....

Since you are new to reloading get just the LYMAN MANUAL. Read it again and again 3 or 4 times and avoid all other manuals until you fully understand the NON LINEAR relationships of bras, primer, powder & bullet. Pressure can build up suddenly by not trimming brass correctly or seating out a bullet too much or just changing the bullet given in a particular load.

I would also suggest you buy a basic chronograph like a Shooting chrony so that you can actually measure the velocity of the loads. Do not try to go higher in velocity than the published loads.

After you get some experience and confidence, then try and look at other manuals and compare the loads. Always pay special attention to pressure & safety.

Remember the NON LINEAR variables - in a max load 5% increase in powder charge may give you 10% increase in pressure but only 2% increase in velocity.

Have fun & be safe.
