View Full Version : Neck Reaming vs. Neck Turning

02-07-2009, 09:25 PM
On a custom 22 PPC target/varmint rifle w/a standard target throat and w/a .245 neck is neck reaming alone acceptable? This rifle is primarily used for non-competitive target shooting & PD hunting. Or, for safety reasons do necks need turning?

I think most people turn the outside of the necks. Some cases require reaming but it probably won't be the sole remedy for making the necks the size one needs.

Neck reaming will open the hole but will not make the neck thickness the same .

Neck turning is so you don't blow cases up or squash primers. (yes, I know it does other things too)

You gotta make some room for that neck to expand so the bullet can leave and go on its merry way. The absolute tightest a guy should go IMO is .0015 all the way around the neck.

neck reaming gets rid of the ring at the neck/shoulder junction and bullets like this because they are no longer in a choke hold; they shoot better typically this way.

Neck reaming will also attempt to square up a crooked neck and this will probably require the case to be neck turned afterward because the wall thickness is going to be all over the place.

Most important, make sure you have at least .0015" clearance between the OD of the neck and the ID of the chamber. This'll read as a .003" diameter difference. (don't mean to be insulting your intelligence, just spelling it out so there's no misinterpretation)

Hope this helps
