I was looking at my brass inventory and im running low on 25.06 but i have lots of 30.06 but no longer have the rifle. I've read a little about it but i've never done it, i figured i might as well use the brass if i can. If i wanted to form some 25.06 brass what is involved in doing this and what are problems that may arise that i need to look for? Thanks! Mike

As Scotty mentioned, you may run into a problem with thick necks.
I always like to have proper head stamped cases.

I agree with having the proper headstamp. You could probably sell the 30-06 cases if they are good shape and purchase some 25-06 which is readily available.

I have done this before, as the others said, its a great idea to have the right headstamp for the right rifle but it is not a huge problem as long as you and everyone who will ever shoot the ammo pays attention to that detail! In my RCBS die set, I have never had any trouble sizing 30-06 down to 25-06 by simply lubing the cases well and then trimming the long necks which will inevitably result from stretching the brass so much. Make sure that you throw these away if you ever get a 30-06 again or keep them separated in a well labeled container. Good luck.

I have about 1000 25 06 that I have formed from 30 06 and 270 winchester. They function great, the component bullets will slide in the case after they are fireformed easily. All that is required is a 25 06 full length sizing die and a case trimmer after you size em. Have fun.
