Randy, Al is on the money on this one..... I checked SAAMI back to the 80's and the maximum cartridge neck is .2615 at the shoulder neck junction and .260 at the case mouth. Reamer demensions are .2625 at the shoulder neck junction and .261 at the case mouth. As you can see if you fire the case once and throw them away you will not have a problem.With the 21 degree shouldder brass flows. I have a friend that worked for Winchester back in the 50's and 60's for Winchester and he says the cartridge Winchester was sued over more was the Swift. I measured some Factory Winchester brass and came up with the mouth demension of .257 and neck junction .2585. over bullet. One can plainly see that if you load many times or some hot ones your going to be pinching the bullet from brass flow. Back in the 50's not many handloaders turned necks for a hunting rifle and got into trouble rather fast. This coupled with hot loads and barrel steels that were not as good as we have today the Swift got a bad name as a troublesome cartridge and a barrel eater. Note that Al is talking turned necks and I am talking factory rounds. Basically if your turning necks or not... A .224 bullet should go into the neck of the fired case with out any trouble. If not you better be turning necks and checking cartridge length.

I have built several Swifts and have found them tho be very accurate and have always informed the customer about the neck situation and have not had any problems. The only thing I don't like about the Swift is the semi rimmed cartrige.. I see Remington now puts out a folder with thier Swifts showing you to load the cartridges from back to front so that you are not jumping one over the other. I have never know this to be a problem anyway... but I suppose it could be.

Randy... with your knowledge of loading you won't have any trouble with the Swift. Just remember to check demensions each time you load.
