Trade-Ex has brass and bullets, Lee Precision has dies.
Roll your own for under a buck a shot, then reload for half of that.
Or try (just TRY) to find some of that RWS or NORMA stuff. Just be sure to take your heart medication first!

As mentioned, Trade-Ex is the place for components.
Back in the pre-Trade-Ex era, after the supply of that nice Winchester surplus cartridge run was expended, I did make several hundred cases out of .220 Swift cases. But then again, I have a metal lathe and other goodies in a 2000 square foot Toyshop.

I can not see any great problems with converting .220 Swift brass to 6.5x50 Arisaka brass.
The body diameter of the 6.5 Japanese is .447 compared to .445 for the Swift, which will blow out easily when fired.
The Rim thickness for the 6.5 is .049 compared to .05 for the Swift, only .001 difference.
The Rim DIAMETER for the 6.5 Jap is .466 compared to .473 for the Swift.
What is going to be needed is a metal lathe and a bit ground to shape. The bit shape should put a slight extractor groove in front of the rim and take about .007 off the Swift rim diameter. This could be done with one light cut so that the rim diameter and the extractor groove is cut at the same time. It would not take much.
A tapered expander should be made to enlarge the mouth of the case to about .260 and then the case resized in a 6.5 Jap resizing die WITH THE EXPANDER ROD REMOVED. This will give an over long neck and you will then have to trim to length. If you do about 50 cases in a batch and trim in a batch, it will be better and simpler.
Chamfer to remove the burrs inside and outside the case mouth. Put the expander rod back into the sizing die, and load as normal.
I checked the dimensions in "The Handloaders Manual of Cartridge Conversions." They recommend the old method of swaging down .270 Winchester brass, but the .220 Swift Brass is a better way to do it in my opinion. A lot simpler too.

Nice thing about using Swift brass for an Arisaka is that both are SEMI-RIMMED cases: headspace on the case-rim rather than on the shoulder.
It is one of the easiest conversions and it works fine.
Only problem is that Swift brass is designed for pressures MUCH higher than the Ari round, so the case is heavier. Drop your powder charge 10% when using Swift brass in the Arisaka.
NORMA and PRVI PARTIZAN both are making it now AND it is available at a reasonable price, so this piece of knowledge likel will enter the Realm of the Lost Techniques.
