I am intrigued by the folks knurling or canneluring slugs. Is it THE solution for a better all-around fit to most barrels rather than specific diameter slugs? I have been disappointed in my attempts to try .22 and .25 slugs - I never seem to have the right size and they shoot like open-choke shotguns at rather short ranges. I can never seem to get them to workout, granted I get quickly discouraged and go back to pellets. I was thinking, though, if knurling or canneluring slugs creates an oversize slug that fits easily into many bore size and easily adapts/crushes to the right size, this technique might be the solution. What do you think?

It may be a solution if your slug is grossly under sized. Or possibly if your chamber is oversized.
Obviously, there are no absolutes when it comes to knurling (or any resizing) slugs.
One thing is definite though, if you are going to knurl, you need to come up with a consistent method for the best results.

I would think a slight skirt pressed-formed into the slug would be easier , more consistent solution ?

I suspect that the best solution is to buy slightly oversized slugs and size them down to the optimal size for your rifle. This is essentially the process used by those casting lead for powder burners. Many of the same issues and efforts existed historically for powder burners, so it seems quite likely that the optimal solution in that sphere will be the optimal solution in this one.
One of the things that makes resizing so nice is that the sizing "die" can be made very inexpensively, to the point that it's just a bushing inexpensive enough that you could buy 3-5 sizes to find the best for your bore.

Might want to check the twist rate in your barrel because no amount of anything will fix a longer slug sent out of a slow twist barrel meant for pellets.
Slugs got to be a snug fit in the grooves as well. If proud .005 to .001 inch that's a good thing.
Slug shape design and where the CG is affects flight characteristics. Some aren't optimal, some are better.
Things have to be right or else.....
After a few more try's I'd look into a different barrel and if not in love with the gun then get another one better suited for slugs.
