Big Country, grinding the bottom of the die is not necessary, RCBS etc., use this method to make custom dies for custom chambers, I short chamber rifles, load for them then go to the range and determine if I want to finish the chamber or use another barrel, all with one set of dies, the purpose for grinding the top off was for sizing a case for a chamber that does not exist in 338, to have a die made in that configuration would cost more than I have in the rifle and to ream a die blank ($28.00)would mean reducing the the neck portion of the reamer, at $100.00 plus to replace a chamber reamer, I had rather dedicate a sizing die for that purpose. I know I could reducethe diameter of the chamber reamer and still ream a chamber if I acquire a reamer for cutting the neck in the chamber.
I size cases with one set of dies from-.016 below a go-gage to infinity.
Grinding the top of a shell holder is not necessary but it is done, Redding competition shell holders are not necessary but if you have them, use them.

BC - I have also turned the bottom of a size die off by .005" or so to get the die to completely size to fit a tight chamber.

RE: opening up dies
Big Country, forgive, I was responding to the post below:
"I have modified the bottom of dies so that head space has matched my rifle before. But dies are too cheap to be opening them up at the neck". RWK did not say what caliber he was refering to in the first post other than 243 and 257.
I did say it is not necessary to grind the bottom of a die, lower the deck height of a shell holder or purchase small base dies.
A custom die is not cheap, a die that is purchased at a reasonable price does not make it cheap or diminish the quality, I need a die that will size the body and a small part of the shoulder, my time and $10.00 for a set of dies made that possible.
I am also chambering a M1917 barrelwith a chamber that uses the case dimentions of the 7MM Remington Mag,as you said, dies are not expensive, I will make a sizer die using a 7MM Remington Mag..

RE: opening up dies
RWK, it was not confusing, just trying to determine what you were doing. Special order catalogs are available for free, to me most helpful, from 4DC&H and RCBS etc. 1 800 533 5000. The catalog list most combinations of wildcats and improved chambers and the cartridge to use when forming a cartridge for a particular chamber, the forming/trim die is listed when one die can be used to from a case as in 30/06 to 8X57, 7X57 etc., many of the listings indicate 'no formingdie necessary, use the sizer die for a particular chamber' as in 30/06 to 8/06. Having both reamers, chamber and die, is a luxury, as I said before I would not use the die reamer to modify a die as in going from a 243 Winchester (243/08) to a 25 Souper (257/08).
As to being a bit confusing, some of this is not for everyone.., my favorite reamersare the 25/06 AckleyImproved and the 280 Remingtonbut that is another story and again a little confusing.
RCBS sells die blanks.

RE: opening up dies
I too have mentioned this;
The 22 250 is parented on the 250 3000 aka 250 Savage circa 1925. It is about .16 shorter than the 308. 250 Savage dies are a shelf item if this is a 1 rifle deal use the 250 die to neck and shoulder and a 308 to body size. Or better yet put it in a new action and hop up a 250 + P.

RE: opening up dies
Shame on me. So a 250 AI would be closer to a 25 08. I'd bet there's a die set for that and proven data. I considered a 25 08 once that was when I found the 250. There have been a couple articals in Handloader and Rifle on the 250.

RWK,
http://newlonprecision.com/
For options, the abover link list die blanks available, the sizer die blank is $59.00 plus shipping, the die is two piece and will take two different piolet sizes, a regular, standard set of dies will do anything a special sizing die will do with the aid of a feeler gage, make cases shorter (small base die) orlonger.
Here is a link to MIDWAYUSA die blanks, http://www.midwayusa.com/esearch.exe/search?search_keywords=die+blanks&category_sel ector=all_products&Click+to+Begin+Search.x=16& amp;Click+to+Begin+Search.y=12
