22ppc neck size ??????

[Any22]

Just picked up a rem. 40x in 22ppc Marked .247 neck Is this the most common size? What size bushing would I get to start ?

A 22PPC bullet is .224. Your chamber neck is marked .247. subtract the bullet from the diameter leaves .023. From .023 subtract .001 for neck clearence. your left with .022. So the maximum case neck thickness would be .011. With that case thickness you would start with a .245 for .001 fit. But it depends on your case neck thickness. Lapua runs about .015(remember x2). Hope this helps.
