Anyone one necksizing only? If it's not too much hassle could you supply the O.D. of the neck before and after expanding it? I'm using PP casings but any will do.

Nope!......I full length resize all my hunting loads and still get great groups and reliability.

Same here.

THANKS guys but I'm not doing it for accuracy or reliability which are both just fine. I'm having a FL resizing die issue.

Earl,

What dies are you using?

DF

Hey Robert
Lyman. Die is hitting the body way before the neck. I can't even partial resize with it. Starting to see case separations.

The body of the case is catching before it's fully into the die?

DF

Not sure whether it's the shoulder or body. Probably will smoke the case and check later. I know it takes alot of turning down of the die(in increments)before I see the neck being sized down and before it does I can feel tension on the casing from the die. I read here a few yrs back about some type of trouble with Lyman dies in this chambering. Of course I can't find the thread. Maybe I should have titled my "Any 9.3x62 Lyman die problems?". Not that it matters now.

What I'm needing the neck measurements for is so I can get the proper straight cased handgun sizing die to resize the 9.3 necks with. The 38 Super die I have seems to be working but I may want a bit more tension on the bullet. Thinking 9mmx19 die.

I had an issue with a Lyman FL sizer with a tight chambered .243. Even sizing using the press cam, I couldn't get the cases to chambered easily. I ground some material off the base of the die until the rounds would chamber easily. The rifle chamber was slightly shorter than the sizing die.

You may want to try another die and see. Sounds like the Lyman die is too tight, or the rifle has a really loose chamber.

Probably the die.

DF

Could be a combination of both. Clearwater rebored and rechambered this rifle. From the measurements I've taken it has a tight neck so maybe a tight chamber overall. Grinding the die is an option I never considered. The neck measurement after sizing in the Lyman die is .002 larger in diameter than the Lee 38 Super die.

Some grind the shell holder or get the Lee set of various thickness shell holders. I like to keep it simple, have my shell holders working all the dies.

BTW, on the 26 Nosler, I had problems with a #4 RCBS shell holder working, so I relieved the lip with a Dremel instead of buying a #38. I later found out that a Lyman Mag. shell holder works perfectly. I had one in a deluxe, 4 die set for the 7RM.

I do like the Lee 4 die set. It has a conventional FL sizer, a Collet neck sizer, a seater and a factory crimp die, including a shell holder. About everything one would need.

DF

Like you I'd rather not be grinding my shellholders. I did have to do a dremel mod on the lip of the #2 shellholder for my Lee Auto Prime Tool. The 9.3 fits my RCBS #3 shellholder fine but won't enter my Lyman #2 which is the one called for.

As far as the 9.3 fl sizing die goes I had thought about having it reamed out to use as neck sizer only. But with my .300 after a number of firings after neck sizing only(I use a 32ACP die)I find I need to partially resize. Should find the same situation with my 9.3x62.

Not sure you can ream one of those. They're hardened steel and I would guess they're reamed and polished, then hardened, but not sure about that.

DF

Does Lee make a Collet Neck sizer for the 9.3x62? That may be one way to go.

If it's going to be a custom order, you may be out of luck, as they're not doing custom orders right now. At least that's what I was told last time I asked.

DF

Doesn't look like it. RCBS makes a dedicated neck sizer die though. I believe the 38 Super die will work but still would like to try a 9mmx19. I've got the word out locally for one to borrow.

Your probably right about not being able to ream the Lyman die. Hadn't thought about the hardening of them.

Earl,

If I don't have a senior moment between now and tonight, I'll get you some measurements on the 9.3x62 round.

DF

THANKS,Robert. That would be appreciated.

I thought I'd figured out how handle "senior moments". NOTES! But I kept forgetting where I put them.

Well said and so true...

DF

Earl,

9.3x62 neck measurements:

Fired --------------------.390"
New Nosler------------- .384"
FL RCBS ----------------.383"
Loaded with 250 NAB -.384"

Hope that helps.

DF

HEY Robert,
THANKS very much. I may have found another problem besides the FL die.

Here are my neck measurements on two cases:
fired--.3895
resized(not expanded)--.379 w/Lyman .377 w/38 Super die
loaded--.3845

I figured your FL RCBS measurement(.383")was with the expander in place so I put in the one that came with the FL die(I use a decapping die). As I measured the necks after expanding I got inconsistant readings as I turned the cases in the caliper. So by applying very slight pressure when I would reach a wide spot on the necks I came up with what I believe is a reliable reading of .383". I'm thinking I need to anneal the cases which just may solve my neck tension issue..

Yes, sizing was with the expander in place.

Your die seems to be really working the brass. Not sure about different readings as you turn the necks.

I've had some good Lyman dies, but would question that one.

DF

This is the first set of Lyman dies I've had that may be causing a problem.

With the O.D. measurements I got w/o expanding I wouldn't think I'd have a neck/bullet tension issue. But I read just awhile ago that one of the signs of needing to anneal is a variation in neck tension. With varying amounts of pressure I can push the bullets into the cases when pressed against the loading bench. And my OAL shortens gradually as I work these dummy rounds through the rifle.

UPDATE:
Did a JB annealing job and seems to have done the trick. Pushed against the loading bench pretty darn hard with no bullet movement. I'll work them through the rifle tomorrow.

As far as the die goes I'll deal with it when I need to. I've got 100 new cases so won't need to FL size anytime soon.

I do appreciate your help with this.

With the new 26 Nosler, I had the choice of Lyman, RCBS and Redding dies. I bought the Redding set, which cost more than Lyman but less than RCBS. Over all, it's hard to beat Redding stuff.

DF

Wow. Redding less than RCBS? Redding will be my choice for the next FL die for this 9.3. I'd also like to pick up a Hornady bullet seater for it to.

Annealing can to the trick.

If your expander ball is doing too good a job, you can chuck the decapping spindle in a drill and cut the expander ball down with Emery cloth. Just be careful, as it's easier to take it off than put it back... Watch your caliper readings as you do it.

DF

First time I've ever had to anneal with this few times of reloading cases though. But it is what is.

I'm using a Lyman 'M' die to expand with. It's a bit smaller than my Lyman expander ball.

Trying to get together the same set up I've been using for my .300 for almost 20yrs. Resize the necks with a 32ACP die,expand with an 'M' die,and seat with a Hornady seater. Case life,feeding,and chambering is fine.
