I've been using the welding drill tip tool discussed here to make sure the tips are good.I've only had one run with the 135's, but only about 75 yards. It was centered through the lungs and just penciled through. After that I've been checking to make sure tips are open and always get a quarter sized exit since.
These two cartridges will take on anything I hunt. What bullet do shoot in your 30-28?
1:7 shoots really well.CrossChoke; what is your twist rate? And as windypants, said he makes sure that the tips are open.
FYI—it wouldn't repeat, so it was just a lucky group from an unstable load. It's shot a number of really good groups that wouldn't repeat. So back to the drawing board.Windy, I triple-dog dare you to shoot that 42.3 group again. Wow!
If you want to be truly objective and scientific, you have to shoot that group again under the same conditions; otherwise, you will never know whether it is a great load or an unlikely fluke.FYI—it wouldn't repeat, so it was just a lucky group from an unstable load.

I'm feeling very confident in my shooting now. I believe I am capable of shooting 3" groups. I can shoot repeatable 3" groups with my 30-28N at that range. Just need to figure out what this rifle likes.If you want to be truly objective and scientific, you have to shoot that group again under the same conditions; otherwise, you will never know whether it is a great load or an unlikely fluke.
When one shoots a really good group, the probability leans toward it NOT having been shot by accident.
Of course, the reliability of your results have a confidence interval that cannot exceed your consistency of marksmanship. But is extremely unlikely that one shoots a smaller group by accident than a larger group. Law of Entropy--small groups don't happen by accident, larger groups do.
And please, no one lecture me on "luck". It doesn't exist.
That's an interesting way to look at this. I've never thought about it like this but on the same note guess I'm already doing it. Whenever I'm working on a new one, once I get a good group I'm happy with I'll still try other things up and down the ladder and if no dice will always go back to where it was good and see if it or I can do it again.If you want to be truly objective and scientific, you have to shoot that group again under the same conditions; otherwise, you will never know whether it is a great load or an unlikely fluke.

Copy. I've been shooting the 133's at 2890 in a 25x47. I have had 7 coyotes run off on me with what I felt like where good hits on the center line behind the shoulder. I'll have to try the 135's.
Funny- my 25x47 is a clone to my 30-28. Great minds think alike.
