    Does anyone have a recipe for a 7 mm Remington Mag using 168 Grain Berger bullets? I would like to start loading these bullets and don't know what powder or load to start with.

    I like the RE22 with the 168 in a Remmy Mag.

    I had the same question not long ago and had a hard time finding good info.

    I have been reloading the 168's in my factory Rem 700 7mm RMag, for a few weeks. I started loading h4831sc, and had some success, my gun took 3.4 grains over Bergers listed max before it started showing pressure, but i had pretty consistent fliers, making my groups well over 1". My velocities got up to 2824 fps. but had a extreme spread of over 50.

    I switched to H1000 and pretty sure i'm hooked. I started low at 66 and quickly worked up to 69 grains, every increment between shot close to 1". Once i got up to 69 i chronied the load and found it at 2849 with an extreme of 9 and a deviation of 4. I shot 5 3shot groups that measured from .290" to .499" center to center. That's what I stuck with and went to the long range. I started at 1000 and it took me 3 shots with a spotter to get on target, and my group was well under 10" once i got on target. There was zero wind that day so it was easy to dope and was really able to see my load's performance and not mine.
    The surprising thing i found was my gun hated having the bullets seated close or into the lands, i have them off 75 thousandths before they started grouping well.

    I'm using the Berger 168 with 71 grains of Retumbo and a Federal 215 primer. I get 2980 fps and I shot a three shot group of .360 outside to outside, not center to center at 200 yards. I shoot the Bergers at 200 because they seem to go to sleep better there. I used the Berger test to see how fat out to seat the bullets and came up with .030 off the lands. I hope this helps. By the way our range is at 2600 feet.

    Dang! What kinda barrel you have on that rifle blkdog? That's a less than one tenth inch group at 200 yds! You better go start shooting competitions and winning yourself some new rifles with that gun!

    It's a Shilen select match on a Remington 700 action built by Ed Sweet, Meridian Idaho. I'm very happy with it so far. It wears a Huskamaw scope in Talley rings and bases. Got a three shot group of .835 at three hundred last week. we are going to 500 and 700 when it quits raining. I'll keep you posted.

    I was getting .5-.75 MOA with my factory Sendero using the following:

    168gr Berger
    64.5gr H4831sc
    Norma Brass
    Fed GM215M primers
    .007" jump
    2906 fps and no pressure

    I tried RL22 and got similar results and wasn't readily able to improve. So, I just stayed with Hodgdon until I rebarreld to 300WM.
