Once fired brass

[Walker1]

I bought brand new brass to load for my 7mm RemMag. Now I am wanting to reload them. What are the steps I should take to do so? Do I full length resize or just neck size? I did not see any noticable signs of too much powder so I want to add a little more powder. How much of an increment should I go up?

Did you load the brass, or did you just buy factory ammo and now you want to reload the cases?

I loaded new brass.

As long as you are firing it from the same rifle, neck size only. As far as how much to increase the charge, it depends on bullet weight, powder, ect. Make sure you are using a book and make sure you do NOT exceed that max load. with the 7mm you could probably increase by .5 grains.

Should I check the length of all the cases and trim them to consistancy?

I trim every time on my rifle brass, just buy one of those Lee case trimming things for 7mm mag, they cost like $6

I will trim to spec. I already have a trimmer from Sinclair. Wasn't sure if I needed to do it again. Do I trim before or after neck sizing?

 

[Jeremybj]

After neck sizing trim it up.

Keep an eye on headspace length. You might have to full length resize after several firings.
