Just Curious????
It really depends on the twist and the weight of the projectile, if the powder load is light and if the velocity x twist rate(to make it simple) is too low you simply drive it a little bit harder until you get decent groups. I can run a 55 grainer down to 1000fps in my .223 and it is still accurate out to 100, albeit with a hideous drop. The only reason I was using 40 grain .22magnum projectiles is I wanted expansion and they were very cheap
If it isn't stabilising usually you get REALLY bad groups and fliers(like 6" plus), when you see "keyholing" you are definately in trouble.
If it isn't stabilising then you just drive it a bit faster.
Whist your groups might not be great, I like yourself love dicking around with diffrent loads to see what will happen and see if you can push the envolope!!! Got my 223 out yesterday and remembered how much I love that thing!!!!
