I have used an extra barrel to check reloaded pistol cartridges such as .40 S&W and .45 ACP but cannot do the same with bottleneck rifle cartridges (unless single shots of course). Does anyone find that the case headspace gauges such as those made by Dillon, Wilson, Lyman and others, are useful when loading bottlenecks? I think it would beat trying to chamber each round in a bolt action or even worse, a semi auto. Your thoughts...
