For any of you reloading for your LE’s, what neck sizing die are you using?

I’ve been picking up gear and will be starting to reload over the winter, .303 will be one cartridge I would like to load for and I haven’t bought a neck size die for it yet. Have looked at the Lee die online, is there anything else I should be looking at?
 
I'm using a Lee,but find that it does not reduce the neck size enough for some of the Russian 7.62 bullets.

To fix that issue I just exchange the spindle with one from another neck sizer,7.5x55 spindle works great.
 
Either one will work.

The 308 case, and consequently the die, is bigger than the 303 case. Set up the die in the press so it just barely misses touching the shoulder when sizing. It will size the neck and not touch any other part of the case, including the expanded base on brass fired in oversize military chambers.

Brass sized this way will chamber in the rifle it was fired in.

Thanks, I’ll have to check that out once I get my reloading bench set up.

I have both RCBS and Lee neck dies.
I prefer the Lee.
The RCBS works by having the brass pushed into a slightly smaller sized neck only die and corrects the internal by dragging an internal sizer thru the neck when withdrawing the brass. This operation stretches the brass in the neck and needs trimming each time.
The Lee, needs no lube, the brass goes in the die to the proper depth, and then the brass is squeezed by a collet from the sides onto a proper diameter decaping rod.
If you partially withdraw the brass turn it a 1/4 to 1/3 a turn and press it again causes the brass to flow around the neck, giving the neck brass a uniform thickness. The brass "MAY" require trimming the first and third time reloaded, but after that almost never.
I have come to prefer the Lee.
 
I use 7.62x54R dies to neck size 303 Brit. Works perfect, same bullet diameter, does not touch any part of the brass except the neck, so you can neck size all the way to the shoulder or 3/4 way or whatever you like. I just happened to already have these and so didn’t want to purchase a separate neck sizing die if I could avoid it.

Will check that out also, x54r is another cartridge I’ll be loading and have dies for already. I will likely be buying a Lee neck sizer anyway as the price is right and everyone seems happy with them but it’s nice to know other ways around it.

I prefer the Lee collet system for .303 British, versus neck sizing.

The other alternative to just neck sizing is setting up your sizing die for a crush fit on bolt closing.

For loading cast bullets to get the best fit in the throat/ball seat, doing this along with NOE's graduated neck expanders allows a reloader a lot of latitude to experiment with in bullet size and fit to case.
