Twist Ratios

[Daryll]

I found this below. Could any of you bullet boffins say as to whether the diagram is accurate?

According to the Venn diagram if I'm shooting a 55gn bullet then this will be good in all twist rates listed ?

Interesting to notice they've missed out the "normal" target bullet of 69gn...but I'd assume it would be somewhere in the middle with 62gn

It appears a good approximation.

There are differences with all bullet/charge/barrel combinations and then ambient conditions come in to it as well.

Thanks Gazza. That’s useful as a guide.
