    I had a gun chambered in a wildcat and would like to have Neil build me some dies. My question is ..... can I just go buy off the shelf rcbs dies and have my smith open them both up with the chamber reamer so I can just neck size and get a few bullets seated to build him his 3 fire formed cases he is asking for ?

    you cannot build a fire formed case.it needs to be fire formed by fireing it in the chamber.

    or are you just wanting to be able to set a bullet on some charged brass to fire form.

    and what wildcat are you talking about?

    Yes I understand that. I just need to get the brass neck sized and a bullet seated so I can fire them. What is the fastest easyest way to be able to get that done ? I was planning on the cream of wheat for first blast.

    if you are useing good brass say Lapua heck any kind will work as long as its in great shape.

    my point is this.if the case of choice is really clean in shape no dents to work out in the neck shoulder it shoudn't need to be sized at all.thats if the chamber size is just over the cases specs.you should be able to load with an off the shelf load useing a seating die from another cal of the same cal.( size wise )even would go as to almost a hot if not a hot load for the case its self and jamming the bullet into the lands.

    this worked great for me when I owned a 300 Ackley useing 300 H&H brass.all I did was fill the 300 H&H up with powder to the bottom of the neck and seated a bullet long into the lands.fired them at the range and they blowed out to the Ackley chamber.and on the first fireing fully formed.

    you must be doing your own wildcat.you have yet said what it is.if it was you wouldn't need to make a die.or you just want a die cut anyway.

    yeah one other way but cannot say how much powder to use you haven't said what wildcat you are going with.but put the right amount powder into the case then top it off with toilet papper then fire it straite up into the air.( keeping the powder down in the bottom of the case )no need to put cream of anything through a bore of a barrel.

    Not trying to be a prk, but if you have to ask, are you sure you are ready for a wildcat?

    It doesnt really matter considering he already has it. I believe your easiest option is to contact Hornady with your reamer specs and they will make you a set of dies in the proper dimensions.

    New brass should fit in your chamber fine. Load seated long & fireform away.

    Bambi you do sound like a prk. I am not as green as I may be making my self sound. To everyone else. He wants 3 cases that have been fired 3 times each. Right now I have nothing to neck size the cases with after they have been fired . After first fire the brass will have expanded enough to not fit in a standard 338 lapua die to just neck size it. There is where I am askin if just reaming a stock die out will get me on my way. I am not stupid I am just not too big of an ego prick to ask questions . Someone may have a great idea . Thanks for the help all. Plott Hound

    If you have a standard HSS reamer you won't be able to cut a factory LM die since they are hardened. If you have a carbide reamer you could probably do it but certainly not good for the reamer. If you don't mind sacrificing a standard sizing die.... have someone with a lathe and a carbide boring bar cut clearance around the body and shoulder with the neck to the only part making contact. It's hard to answer without knowing exactly what the chamber specs are. Did you buy the chamber reamer? If so you might be further ahead to just order the sizing die from the same company, send both to the die guy and get a sizer and seater made.

    If I knew your chamber dimensions, I might have an idea.

    I've found myself in a similar situation, all the generic neck sizing dies that I've found that might work make a large price jump when going to that size case so I'm just going to make a neck die out of some scrap metal that will take a Redding bushing. Any machine shop should be able to kick you out something for a reasonable price that would do the same.

    Knowing that you needed it fired 3 times helps. Now, what is the cartridge?

    just how much of a difference will the case come out.if we are talking about an ackley you should be ok with just one good hot 338L load to fire form with.then you shouldn't need to fire the other two times.again the 300 H&H case is alot or a long ways off from a 300ackley imp.take a look if needed.trust me one good hot load from your past loads if so should work for you.

    or again fill the case with the right pistol powder( charge ) and keep forming it that way if you really need to fire it three times to make sure.the 1st fireing on the cases shouldn't keep you from fieing them again.I would think they would still chamber.but hey I must be missing something who knows.

    I had this same issue when I had Neil Jones build my dies for my 338 LAI. Yes, reaming out your die will work but you my need to ream the seater die out too. I do not know what dies you have?

    I did it the easy way :). I made a tool for shell holder and put a redding bushing in a collet. I used a Bridgeport vertical mill to neck size the case. I used this same setup to seat the bullets. I simply took the seater out of my die and put it in a collet and seated them all.

    Either way you will need a machine shop to get you rolling, unless you have access to one or have your own.
