Just a quickie.

I've got a good few .270 once fired Remington shells, an a handful of once fired nickel Winchester(supreme) shells that im goin to full length resize to .35 for my whelen.
I also have a handful of 30-06 brass (but will be getting more an more quite easily)
and Also once fired 35Whelen brass fired from my rifle.

My question is, if i resize these an load them up with the same powder weights, will they perform similar in the field, an on the range....
not sure if yas understand that but say i've used the 270 resized cases to sight in my load, if i use say the original 35brass (or 06) will they all hit the same POI with same Vel etc...

Hope yas make some sense out of this, put it down to a new lad on the reloading scene.

Thanking you.

Iceman is right. The only way to tell for sure is to try it. My bet would be that they won't all shoot to the same POI. Different cases have different volumes and thicknesses that produce variables. I would divide them into lots and use them that way.

I would also throw out the nickle plated cases.
 
the ones with the closest weight to each other will (90% of the time) be the ones that group/ show pressure signs at the same time

(all trimmed and sized to the same length)
as you could have 20-40g up/down in brass weight or more
 
I would try it, but definately not with max loads!!! I have always sorted my cases by manufacturer, if the 270,30-06 and 35 whelen are all made by the same manufacturer they may have the same internal volume after resizing as the 30-06 is the parent case for each.
 
35 Whelen brass hard to get in Australia?
"...not sure if yas understand that..." You mean does the starting case matter? No. You're just changing the diameter of the case mouth. Probably better to use .30-06 though. Not as much of a change. .270 necks will be stretched much more and will be thinner.
"...will they all hit the same POI with same Vel..." They should be.
 
In your case sorting by weight is better than sorting by brand. I mean a 35 Whelen case may be made heavier than a 270 case by the same maker.
After what you term resizing, but is actually fire forming, the necks, meaning case length, may not be the same. This would change the weight. But if the cases are same length, then the cases should have the same capacity for powder, if they weigh the same, within a couple of grains.

Good point H4831, would have never thought of a manufacturer making a case heavier for a former wildcat than the parent cartridge. It could make sense as far as case life goes. Now in theory, if its actually done, reforming 35 whelen cases to 30-06 while treating the cases well would make a much longer lasting 30-06 case, albeit with slightly less powder capacity.
