just got a Hornady die set for 300 win mag. :confused:On resizing i find it quite stenuous to drag the neck sizer up through the neck. going down is good. cases lubed, graphite neck lube, Hornady dies.RCBS single stage rockchucker I'm almost lifting my bench up on the return stroke. Is this normal?
I'm used to reloading 308, 30-06, 6mm with RCBS dies; the return stroke is no where near this hard !
 
I had the same problem,so I build a heavier bench.I load 270 and it's much easier.The only thing I have to watch out for on my Dillon is on the return stroke be careful that the primers don't flip on their side or up side down just before I seat them.:)

It could be lube, brass, or expander button. My bet would be it gets better if use better lube.

Hey jonnyrc,

Yes, I too had a b**ch of at time when neck resizing, it's normal, wait till you try try full length.... :eek:. As mentioned before use abit more lube or try a different brand. I was using the RCBS lube that came with my partner press kit and I didn't like the lube very much.

Cheers.

I have the same problem with the Hornady dies. I tried to polish the button to make it smaller and smoother. Did not help. I don't think more lube helped much, either.

My work-around is to remove the Hornady decapping pin and use the die to size only and use another die to decap. If you bought a 7mm decapping pin/button from Hornady, the problem would go away.
 
i have the same issue...my neck turned ammo comes out no resistants..
but my hunting ammo is a bugger like u said lifts the bench ,,,lol,,,i do not lube inside necks....
 
you're using dry lube i hope, motor mica or graphite or powdered moly and a small bottle brush, use very little lube.
 
jonnyrc,

Get a very small jar, and fill it with #8 shot. Your wife might have one of those super small (and super expensive) glass makeup jars - they're perfect. After it's almost full of shot, add a teapoon of powdered graphite. Before using, just flip it upside down, and push your case necks inside, just down to the shoulder. It works great. Be sure to clean the inside of your case necks with a bore brush. You're looking for trouble if you reduce the diameter of the expander ball. A carbide expander ball will reduce the need for the graphite, and they are a huge improvement.

However, if you really want to get it right, use the Redding (Bushng type) S-Series dies. They don't need an expander ball, and you'll have much better control of neck tension.

I use regular redding dies and no problems.

And I don't quite understand why a case with one of the shortest necks going is giving you guys all this grief? Unless they made the neck of the die tight to aid in bullet retention on the short neck. Maybe take the expander rod out and see just how small the die is squeezing the neck?
 
These days, I lube the inside of all my necks with the cheap Lee lube (it resembles a tube of toothpaste). I simply dip a Q-tip with a tiny bit of the stuff and roll it around the inside of the neck.

It makes a NOTICEABLE improvement on the upstroke.

I've also found that this Lee stuff is relatively inert. Not much remains after the expander ball passes. (The expander ball actually scrapes it up out of the case on the upstroke.) What little remains does not need to be removed, unlike oil-based lubes. You can simply reload the case without worrying about your powder being contaminated. It's a cheap and easy solution, and it works.

Another option is to try the Lee Collet Neck Sizing Die. It requires far less effort on the upstroke (the downstroke is another matter!). Still, I find I have to lube the inside of the necks even with this die.
 
I use a 30 cal bore brush lightly lubricated with whatever case lube I have on hand and give the inside of the necks a couple of strokes. Works perfect for me with regular old dies...
