Put the 168 bergers 3-5 thos in the lands then try 61-63 grns imr 4350 or 62.5-64.5 grns imr 4831 I bet your groups tighten up.

Re: 7mmRemMag accuracy troubles

I have had good luck breaking it down to finer increments than what Berger suggests. I use .010 increments out to .040 and I haven't had to go shorter except when restricted by a mag length. I have a couple of rifles that like the .015 range. Bergers can be finicky, no doubt but worth it IMO.

+1

Also, I have two rifles that are my personal rifles that like the bullet jammed .005. They both shoot around the .7 range @100 and some days a little tighter but they both hold about 1/2 moa out past 1000.

Re: 7mmRemMag accuracy troubles

i got higher velocity, sd and es with the 215s. i would not shoot the std rifle primers and i nwould not shoot the 215s. . i would shoot 9.5m , 250s or wlrm. are you shooting targets or hunting?? with those high bc bullets you may want to try around 2850 to 2950 fps

It's mostly LR target shooting, but I also will be hunting from 600 yards and in with it.

In my 7MM Mag with 168gr Berger's it liked RL-22 & also H-4831 work well too.

Re: 7mmRemMag accuracy troubles

Federal owns CCI by the way and if you call and ask them they will tell you if you can not find 210M's to use CCI 250's so I guess that makes them about the same. Now if your hunting at 35* and colder a 215 gives better ignition when its cold. Finally someone agrees with RE22 and 4831!
