You’re right, but I think there are two important points to also consider in your evaluation. 1) monos typically require a little more velocity to properly expand than their lead cousins, so the typical recipe for higher velocity is a lighter bullet. 2) monos typically shed less weight during penetration, therefore a lighter mono bullet becomes the same weight as a heavier traditional bullet after the traditional loses XX amount of grain a few inches into impact.It is well known that mono's made of a lighter material and will be longer for the same weight. So in order to stabilise properly, you will be using lighter bullets. Many people try to spin that off as an advantage of brass or copper bullets- you can use lighter bullets to do the "same" job -not strictly true.
To me the reality is you need to use bullets that stabilise in your rifle or your groups will look like a shotgun pattern.If that is a 165 gr, then that is what you need to use, regardless of whether you like a 180 or 220 gr bullet. If a 180 gr mono will stabilise, I would go with that. Otherwise work my way down through the weights until I get an acceptable group.
