When it sizes, it doesn't seem to size the complete neck. Will this interfere when the neck is turned? Should I size the neck with a different die prior to turning?

I usally turn the necks on new brass first before I size. The exception to that is if the brass has been dinged up in shipping.

I haven't found neck turning to really help that much on a normal chamber. Tight neck chambers do help on accuracy.

Doesn't sound as if you have the bushing set up right. Mine will size the entire neck.

Thanks.

The Lyman neck turner instructions say to run the brass into a full length die first, using the expander. My Redding bushing die does not size all the way to the shoulder, so you can not neck turn using my bushing Type-S FL die. Depends on what outside neck turning tool you have.

+ What 243winxb said...FL first then neck turn..with Redding Bushing dies...I turn necks not necessarily to fit a "tight" chamber but to make the necks uniform in thickness...usually about 80% or 0.0005" leaving some unturned neck and the whole length of the neck.

After one firing the pressure pretty much evens things out and gives an even bullet release...supposedly...no way really to know for certain other than firing some groups prior to neck turning, then after and see if you gain anything.

I make it a practice to neck turn all my calibers along with weight sorting, trimming, deburring flash holes and uniforming the primer pocket...basically benchrest prep all my cases. I also "Tune" all my rifles by glass bedding/pillar or full bedding the receiver, floating the barrel, shimming sight bases...all the little things...I won't have a rifle around that won't do a 1/2" 3-shot group consistently and that includes all my big bores through 50 cal.

The rifle and ammo HAS to be tuned very well before you might see any real group reduction and it also depends on the shooters ability...neck turning ISN'T a panacea for bad trigger or bag work or in a "not so perfect" rifle.

But you have to start somewhere and neck turning is as good a place to start as any.
