I just picked up my first Krag a few weeks ago and, courtesy of my wife, got a Lee single stage press kit and started loading for it. I sourced a few hundred pieces of brass from friends and a local reloader who had some extra to sell. I also found a couple boxes of Winchester and Remington 30-40 Krag locally and bought those as well.

At this point I've got about 350 pieces of brass total and now need to make it last as long as possible given the extreme difficulty in buying or finding more at this point in time.

With that, being new to reloading I'm aware that neck sizing a fire formed piece of brass should give you more reloads before failure than full length sizing each time. My question is, how much more use can you expect to get with just neck sizing 30-40 Krag brass? Right now I only have a FL sizing die so I'm curious if it it's worth it to buy a Krag neck sizing die or not. If it is, which die should I be looking for? I've seen several different versions ranging from $25 (Lee .30 cal universal neck sizing die) to as much as $100 (RCBS 30-40 neck sizing die).

Sorry for the dumb questions but any thoughts or experience would be appreciated.
