168gr Bergers, CCI Magnum primers, IMR4350, seated just short enough to fit mag in my Tikka T3 Stainless is sub-moa all day long. I will not post load because you need to work up, and what works in my gun may not work for yours.

Lefthook do you know the feet per second?

I never put it through a chrony, it's just a very accurate load in my rifle and it is deadly for anything I'll be pointing it at. Looking at published load data I would think it's at least 2900 FPS but don't quote me on that.

I run a 23.5" barrel on my 7 mag.  It has become my most accurate magnum to date.  It still can be finicky with heavier bullets, but it absolutely loves 140 grains of all flavors.

Most accurate load is actually the bullet I like the least - Partition.  Bullet that seems to perform the best in the field has been the Accubond.  Both well under MOA using the same powder charge, just different seating depths.

Case: Hornady
Primer: CCI 250
Powder: Norma MRP / 68 grains

Accubond in this gun likes .005 - .010" more jump than the Partition.  Have not seen a change in group size whether I load at that .005" or .010".  I did not add it to my notes, but if I remember right that means .025 - .030" off the lands for the AB and .020" on the Partition.
He asked, Do you ever give a short simple answer?  I replied, "Nope."

 Have not hit a shoulder but heart lung areas have proven to be effective. :twocents:

 Incidentally, I load he same 140 Partition for my kids to use in their 7mm-08's, makes buying bullets easy. ;)

I just chrono'd this load last weekend. The average came out to about 2940.
I hunt, therefore I am.... I fish, therefore I lie.

Wow! I had no idea, just shoots great out of my 700. That's nice to hear, doesn't seem to be a throat burner, I been shooting it for years. I took my neighbor out and we could plink with it like a .22 and nail milk jugs at about 300 yds with no problem. That was just dinkin' around not really trying to do anything with it.
