So I finally found a box of new 7.63 x 25 and it worked great in my TT-33. It was a nice light report and at 12 yards it shot well. At 15 I was all over the place but that was the cold and me. I tried this a few months ago but the 30 mauser I had was rather old likely 70-80 years.
Here is a video of the new stuff vs 7.62x25
The price is crazy for 7.63 but the brass can be reloaded.
