So certainly less than a 348fps gain, if your AHs weighed the same as the 180gr Bergers.Never shooting a bullet below the 169 HH weight I’m at a disadvantage to give a apples to apples velocities comparison
I shot 180 grain Bergers at 3000+fps
All the time.
The 155 AH gave 3348 fps!
And great accuracy
So each of you consider that when working the new bullet up
Hey Brother, Send me 50 of the 30 Cal's as soon as you get them going, I'm chomping at the BitWe got a 30 cal 10" twist bullet drawn up yesterday. We will shoot this one over the weekend. It is a slightly diff dimension with greater bore to groove dim. So we want to shoot it at distance and make sure it doesn't do something wonky.
For everyone looking for load data for the Absolutes. There isn't any. This is wildcat load work. Best thing to do is work with known powders for bullet weight to get a base line for pressure and vel. Then make a determination of where to go from there.
If anyone is not comfortable with load developing the unknown, then this is not the bullet for them. This is for expert reloaders.
We will be loading the 123g AH and the ~180g AH this weekend in multiple rifles. Assuming we get enough time. We will start with known loads in these rifles for the bullet weight and see where they go. Then determine what powder to try after that based on case capacity and how close to pressure the 1st powder was.
As time goes on there will be more familiarity.
