163gr 25cal chinchaga bullets

[Bghunter338]

LOL! I was anticipating someone was going to make pills that require a 1:7' twist, so I went with 1:7" in 2021. I am hoping Dale does something similar in .22 cal.

Right, I could use something in the 90gr area for my 22-250ai

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 lol

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 units…or maybe a stroker

Going to be interesting to see the 135vs145vs163 and the range each over comes the others.
That's a lot of bullet headed down a small hole.!

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.

Did you decide on 5 or 6tw?
Velo looks good for that payload!
