Ran into the same issue with the large CherryMax rivets and HF puller. I was able to finish setting the rivets using a squeezer--the steel mandrel makes a loud pop once it's driven in properly (that's the second pop that was missing when using puller) and ends up flush with the top of the rivet.

What do you mean by a squeezer. As in a solid rivet squeezer?

Affirmative.

Vans has a video describing how to lubricate the mandrel/stem on CherryMax rivets to address this issue (old rivets are the cause IIRC): https://www.youtube.com/watch?v=lb9miRllZDo

There are numerous causes of the rivet not setting properly.

Another one is alignment. If the tool is tilted to the side slightly, it tends to add additional tension load on the river stem and can cause it to fracture prematurely.

My kit is a few months old, and the -5 rivets don't look any more aged than the -4 ones that set perfectly every time, so I doubt rivet age has anything to do with it. I am using an "unapproved" puller so Ron's explanation fits. There are only a few of these big CherryMax rivets in the entire kit, so touch-up with a squeezer is much more economical than getting a special puller, making a mess when drilling out, etc.

Thanks for the video pointer, I'll try the lubricant trick next time.
