I didn't read the whole thread but the first forming of cases came with a recent project. I've always wanted a 250 Savage. Buying a new rifle has become impossible, so I built one. Bought a savage Model 11 and screwed a 250 Savage barrel from midway into it.
Searched for weeks online and every local shop I could find and finally found a box of factory loads. Finding brass was even harder. I searched and found two options Necking up 22-250 or necking down 6.5 Creedmore.
Tried both. Works fine.

My first was 7mmTCU from 5.56, that was my first cast boolit experience too.
Bought the lee 130 grain mold, and a lee lube and size kit. Back then it was a hammer die. The lube was 50/50 alox beeswax came with a flat bottom steel pan and cake cutter.
First load worked real good h322 POWder. What a rabbit hole I fell down!
Okay, okay clear the cobwebs away, my tip for you 35 Whelen fans, brass made from .270s finish a little longer than brass made from .30-'06. Having some brass to trim off after stretching the neck gives you such a nice square mouth, and cuts away any micro cracks that may of formed.
My method is, size the brass in RCBS 35 Whelen size die, which came provided with very nice tapered expander ball.
Then run .375 "M" expander into neck.
Then resize again with .35 Whelen die but a 7/8 washer is under the die lock ring.
The resulting bump in the neck makes it hard to close the bolt on fire forming. But forces the head tight against the bolt.
Case formed this way have a much longer life, and much better ignition reliability than cases formed with one trip through the size die.
Yes I used plenty of lube inside the neck.
I have not annealed before doing these steps, but probably will If I ever need any more cases.
My loss ratio due to split necks was 4-5% using .270 range pickup brass, and 3-4% using .30-'06 range brass. Gentile feeding would most likely reduce losses to near zero, so would an anneal.

My first experience came with a .25-06 rifle. Having several thousand rounds of Frankford Arsenal .30-06 Match brass on hand I proceeded to take care of that need quickly and easily.
Later a nephew purchased a new .270. A couple of hundred '06 cases provided him with everything he needed to make .270 ammo.
About 20 years ago I found a pristine Winchester Model 43 in .218 Bee. Could not find any ammo or brass for it, but I did find some .25-20. Short learning curve resulted in a usable supply of brass for loading .218.
An old friend has his father's captured Japanese rifle, which was converted to 6.5-.257 Roberts. His ammo gets produced in my shop.
Another old friend persists in using a 8mm German Mauser that was converted to 8mm-06 years ago to allow its use with .30-06 brass (before European ammo was easily had in the US). He brings brass and beer over and we make it happen pretty easily.
When a .243 Winchester came my way I had hundreds of rounds of once-fired 7.62X51 (.308) on hand, so I converted a few hundred for use.
Most of it has been simply resizing or changing neck diameters. But a good case trimmer with neck reaming cutters has been needed more than once. I can't claim a 100% success rate, but I doubt that I ever lost more than 5% of the brass I started out with.

First was 8mm from 30/06. Made a bit of 300 Whisp-R out of 357. 7.62 Tok from 223/5.56 and lots of 300 blk from 223/5.56. I use 308 to make 45acp shot shells.
Most recently I made 280 Remington from a bit of 270 that was given to me. Ran them through a 30/06 die then back down in a 280 die. Still need to fire form those. Hope they turn out well.

First was 30-06 to 250-3000 I only got 1 to chamber, then 270 to 7.65 they work great, then 22-250 to 250-3000 easy, next 223 to 300 blk, They are all easy to do when I anneal them first.
