163gr 25cal chinchaga bullets

Your welcome, I'm going to have to start a thread on my 25 souper when it gets done. I'm going to try the 145s in it and watch the negative Nancy's heads explode šŸ¤Æ lol šŸ˜‚
We were looking at building a 25 Souper (1:7) or 25x284 shooting Berger 133s & 135s. Very interested to see what you are getting with the 25 Souper build you are doing. You might make my ideas a reality.
 
Bearing surface LOOKS pretty similar, there.
Better have a big block carrying those unitsā€¦or maybe a stroker
Here's the cases that's pushing them. Last time out I pressured out at 3036fps

H1000 with 163 Chinchaga .015" off the lands.
@Bghunter338, as per our text, I Chronoed 4 out of 5 until I ran into some issues (not Chrono or load issues).

62.0 = 2866 FPS
62.5 = 2879 FPS
63.0 = 2904 FPS
63.5 = 2915 FPS

Overall, not too shabby out of a 22" barrel.
