Have a Magnetospeed chronograph on the way. Any tips on how to use it for load development? Thanks

Don't. Target is all you need.
Can tell you if your E.S is waaaaay out of the park but besides that the target tells the story.

You might want to find a way to mount it so that it's not attached to your barrel. I did that and it helps, but you still get some deflection coming off the bayonet, though I didn't find any really degradation of group size. If you're attaching it to your barrel(s), you can still get some reading as to what load produces better groups than others, but you'll need to have the MagnetoSpeed off the barrel to get a good tune to your load. Just the velocity information alone (the MagnetoSpeed being pretty accurate and consistent) can be helpful in representing how well you're reloading your cartridges or not. The bottom line and true test is always what the target tells you.

I suggested eliminating pieces that were causing fliers. Come up with your own method for doing this.

A 22 is not going to help solve your problem unless you have a 22 and ammo that will shoot tight groups. Easier said than done. If you don’t, you will be seeing fliers caused by inconsistent 22 ammo.

I agree to a point. If you're having bench form problems, that will show up with a 22lr also. And it will teach you about wind. If you're working on your skills, you can shoot a 22lr A LOT for not a lot of money. You won't have good results from bulk boxed ammunition most likely. It doesn't cost a large amount to get better loads though. Doesn't have to be 'top shelf' unless you're already a good shooter.
If you're already shooting very well, then you've advanced beyond this and yes, it's not nearly as beneficial.
Just my thoughts, many ways to work on improving.
