Can a 280 Ackley Improved case be resized to a standard issue .280 Remington?  I ran one through and it looks "ok" but, you can see where the crease was for the higher shoulder...

I'm thinking this is not a safe practice... Common sense tells me: the pressure COULD shear the case at that crease/seam

But thought I would throw it across those with more real world knowledge than myself...

purely conjecture on my part, but, i think the cases would be ok to fire, but you will likely run into severely truncated case life due to work hardening.

the case has to be blown out to get it acked, then you are sizing a ton of that blown outedness (tech term) back into spec... handloaders who ram their fl dies down to the shellholder and just size away run into short case life issues (and they are just sizing a little bit of what you are)... you would be doing the same thing - an order of magnitude bigger, though - so i can't think the effort would be worthwhile.

Hunting is not a matter of life or death; it is much more important than that.

Schlep;

I agree with Dakotasin.  I imagine 100 new .280 brass should be running about $22.00 in your area, that's cheap.  Trying to put the pig back into the poke, well that's work.

I bought 60 once fireds from a fella on ebay...  he didn't know there was a difference.  I got 5 Ack Imp'd cases...  I ran one through for spits and giggles... and then was just curious about it.  I have no intention of actually loading them... he said he'd replace them, no sweat...

Have you tried annealing them? Just roll the neck and shoulder area in a torch flame until they are too hot to hold on to and then drop on to a wet towel for cooling before sizing. It will soften the work hardened area and may relieve your crease. However, I agree with CB whole bunch of work for little return compared to the cost of new brass. RD
