[QUOTE="yobuck, post: 1552978, member: 12443"] No argument is intended, But fact is, neck turning is, or is isn't a requirement, determined by the dimensions of a custom chamber, and "not" based on the desire to do it or not do it by an individual. Some shooters "prefer"to just true up the necks by taking just a very small amount off the high spots. Especially if the neck size has been reduced by any appreciable amount. It may or may not have an affect on accuracy, but it will have none on the velocity of the cartridge unless the neck is tight, and is causing high pressure. Fact is it would be easy to ruin brass as a result of neck turning for a chamber not requiring it. I would suggest taking a fired case from the gun in question, and "without" resizing it, try to put a bullet tip first into the case. Even a loaded bullet would work for that. If it goes in without resistance, for sure no neck turning is needed, and would be typical of factory chambers. If it goes in with a very slight amount of resistance, that would be typical of a custom no turn chamber. Of coarse if it wont go in at all, or without a fair amount of force, then turning would be advisable in order to keep chamber pressure under control. Many "good" gunsmiths, will indicate the neck dimensions on the barrel after they chamber it. [/QUOTE]
