Which primer for 7mm rem mag loads?

[elmer deer]

Should I use a magnum primer for reloading 7mm? Or could I use cci Benchrest 200, The powder I will be using is rl22 or imr7828 with 140 grain and 160 grain bullets primarily. Or any other sugestions on what has worked well for you guys? I have been using cci br2 for my .280 with great results, so I am just wondering if I should change to a magnum primer?
Thanks
Elmer

RL22 likes high pressures. I suggest a Federal 215.

Gee, never thought I'd be telling Elmer what primers to use! Well, I generally use Federal 210 (standard) primers in my 7mm Remington Magnum. I have tried the magnum size with that case, and did not find any advantage. I use a 175-grain Nosler in mine, and have discovered that for that heavy bullet, IMR 7828 gives higher velocities than RE 22 and the accuracy is about the same for both powders. However, RE22 might be better for lighter bullets......

You can never go wrong by following the reloading data. If it calls for a magnum primer use it.

I use 215 GMM's in my 7mm rem mag/140-160gr bullets under both powders you mention.

RL 22 has been my choice for 140 or 150gr and IMR7828 for 160gr.

i use imr 40-65 or imr 43-50 im my 7mm mag with a magnum primer and it shoots sweet and accurate

We all love our 7mags, however, there is no load that I have ever seen that requires a mag primer....none, zero, nada. Having said that, if you are shooting above the artic circle in February....you might be better served with a mag primer. Other than that, there is no reason to consider this primer......in fact, there may be reasons to discount this primer......excessive chamber pressures, elongated primer holes and reduction in case life, pop up on my radar screen. The dead deer could care less if the bullet is going 3100 or 3110....don't fight city hall on this one.....save your brass and read what every manual says. Regards, Rick.

I agree with bigcountry, loading for 3 , 7mm mags, we all like RL 22 and 215 mag primers.

I have to agree why buy a manual if you can't follow it .

I like the slow powders in that case, and i always use mag. primers.. I do like the fed 215's because when it's cold out i know they will get things going in that case...

Slow powders and cold temps =mag. primers.
