If the data is correct and 78 grains will only be 3100 fps I may not even try, like I said I suspect the data is wrong. I've found the max load for the Triple Shock and it's 78 grains and it's very loud compaired to other 78 grain loads. I'll cronograph the 78 grain Triple Shock and find out, my gun usually like's 77 to 77.5 of RL22, but if I can't be at 3100 fps what is the point.
The data might be quite correct for the rifle used to develop the load, and be very far out of whack in YOUR RIFLE. In fact, it would be a miracle if it were NOT!!
As Bob Hagel said,
"a load that proves to be maximum in one rifle might be quite mild in another, AND VICE-VERSA."
Get a chronograph, and test the data in your rifle. Then you will be closer to a correct answer, and not just speculating, or worse yet, depending upon the speculations of others!!
