Do you smart guys see any problem with necking Lapua 22-250 brass up to a 250 Savage, for a model 99? 50 or 60 years ago I necked 250 savage brass DOWN to make 22-250 brass- worked fine, and I neck '06 brass up to make Whelen brass with no neck problems.

Nope.
Wait, I see you asked for smart guys.....sorry.

Thanks, dpcd. I have 6BR dies, which should make a good intermediate step if needed. An old friend just gave me a Sav 99; at junior hi age, when we started deer hunting, I had a 30-30 and we used to argue about which was better. I'd tell him that that puny 250 wouldn't kill anything bigger than a jackrabbit and really get his goat. He shot many deer with it and even got a BIG Roosevelt elk. We grew up in
Western Oregon.

I hunt Javelina every year and I'll try to get it shooting for my next hunt. We're both pushing 80 and he's getting too old to hunt.

Smart Guy??? Oh well. I cannot see a problem. You are "working" the brass and may lead to sooner neck cracks. Annealing can be cone in molten lead, pure lead if you wish to be super safe. This is not a big step and as you state, going the other way, .250 to .22/250 was done a bunch. Luck. Hapoy Trails.

Once fired 22-250 cases run over a 243 expander then sized in my 50 Sav FL die backed off just enough to have a little resistance when I chamber the sized case.Anneal load and fireform. Perfect cases everytime

Make that my 250 Sav FL die

smart guys instead of smart azzes- guess i won't answer

I don't see any problem expanding a .22 neck up to .25.

I made a series of long taper expanding plugs that fit in my Lyman M2 Expanding die for .35 and smaller necks , and another large diameter, long taper plug that fits in a .375 RUM size die.

I regularly expand 7 mm RUM up to .375 RUM in one step. Just lube the inside of the smaller case neck and push the expanding plug through it.

I do that, have for the last number of years..I would rather neck a case up than neck it down, necking down sometimes requires inside neck reaming...the only thing that's bothersome is if you shoot a 22-250 you might get the emptys mixed from time to time if your not careful....No need for special tapers as its a easy fix..Just run the 22-250 through your resizing die and your done, the case will be a tad shorter so you won't have to trim for a number of loads...

You can neck and down any brass.

If you are going up, or down, several calibers, you need to use several stages, and have to have the right tools.

Thanks, guys, got it handled! Ray- I wore out my 22-259 barrel years ago shooting sage rats; it's now a 22BR. Nothing to chose between the two, in my opinion.

I've necked them to 6.5 Creedmoor in one step, then fire forming them....before you could buy Lapua cases in 6.5 CM

I had a 6mm/Intl that was AI'd..

Used a Redding Type S die (.22-250 AI) for sizing and a .263 bushing. Redding makes a couple tapered sizer balls; from 17-26cal and .24-.358. See their catalog.

I made .260rem brass from .308win Lapua. Used a .297 bushing as an intermediate step.

Redding also has tapered caliber specific size balls, usually these come with the AI die sets.

I dunno about neck trimming, like super long necks, resulting from case-forming; but a Wilson trimmer kit with correct case-holders is a very worthwhile piece of gear.

Yes sir, and what Saeed said is true but only in some cases..22 to 25 going up is not a problem, nor is 30-06 to 35 whelen for example. I would venture to say if you can shoot a lesser caliber in the gun with success then you just resize it in the Whelen die, same with the 250-3000.....Example a 22-250 can be shot in a 250-3000 to fireforn it, same with a 30-06 to a 35 Whelen or 338/06, just shoot the loaded 30-06 in those two calibers..Necking down in some caliber may need to be a two stage process, sometime 3, a bit at a time then fireforming is usually required..That said, I buy 22-250 brass and take one pass thru the 250 die and Im done abd no need to firefrom..Almost the same with 35 and 338 on 06 brass, one pass thru the die and your ready to load, as a rule, depending on the shoulder with these two or the 250 also if its an Ackley , then fireforming is necessary with it..
