I need you guys to help me decide if the results I got this weekend are what I see at face value or if I'm causing other problems.
I have been developing loads for a 200gr FTX in my 35 Whelen AI so I was excited when I saw Winchester come out with StaBALL Match. I had been using W748 for this same bullet, and Winchester markets them as twins in burn rate. I loaded up a ladder of StaBALL with the same brass, primer and die settings as my W748 ladder. I got to 2865 fps with W748 but only 2732 fps with the StaBALL match. These numbers are 3 shot averages of the highest velocity load that didn't have visible pressure signs on the brass.
So what gives? Is W748 really that much more energetic than StaBALL Match or did I miss something? IMR 3031 got me to 2947 fps safely so I'll probably abandon both Winchester powders regardless.
