MOW, I will assume that you are referring to the 7mm RemMag.
My favorite reduced load for that round is 50.0/IMR4320/130 gr Speer BTSP/2681 fps. Note that I'm using 4320, not the more-common 4350, a slower powder which has been accused of rare detonations with reduced loads in overbore cases.
I have also shot this load with success behind the same 130 Speer: 49.0/IMR4895 for 2656 fps. Accuracy is excellent, just a bit over 1 MOA.
I like the 4320 load better only because I have lots of the powder.....I still have around 12 lbs of the 22 lbs of 4320 I bought at an estate sale years ago. And in these days of acute shortages of Re-15 and Varget, it's good to have an ample supply of IMR4320, which gives a similar performance to the other two.
