a bit different-22WMR Question

Most questions in an ammo thread usually have to do with reloading or from what I've read or posted myself, Factory centerfire ammo questions for hunting purposes...well I now have a rimfire question and, here again, it's not the normal "what's a good LR round for plinkin' or small game.....

I need to know if anybody else, besides me uses the good ole .22 WMR to take varmints OR better yet, the exact way I use it...during fall turkey season (I hunt PA). We generally will team up during the fall season, one with a shotgun, one with a varmint rifle and go bust up a flock.

Anyway, in years past, many have used .223's OR .222's, which work just fine...but can be too much at times, blowing away good meat. The .22 WMR has proven to be just right...along with the old 22 Hornet...but I don't have one of those...wish I did....so, POINT....

What's your favorite .22WMR round? What have you found to be the most accurate? Most reliable (I still run accross "high end" rimfire ammo that doesn't go "bang" when it's struck)? Just best performance overall?

I've used the Hornady V Max, but I have a question about that too. Why are some red box, red tip and others blue box, blue tip with the exact same data printed on the box, & they are the same weight bullet?

That's about everything.
