How difficult is to obtain parts for these calibers?? (.22br, more)

[Hiaboo]

I have a gentleman who has a lot of things to sell from his grandmother's husband who just passed away and I am consiering buying if the price is correct and can find the funding--

.22br .220 swift, .222 .260, .284, 6mm 6mm-.284 and more. I don't have all of the details, I will have to find out more about the rifles, who made them, etc. THe gentleman told me they were hardly used and 100% mint. I looked up the .284 and all I saw was old Winchesters and they were about 1,000$+

I am buying the powder and primers from him at least. He has dies, presses, everything to reload the above.

My question is, what should I look for in those calibers, anything special and what would be benefital to both parties (price wise, etc)

Feedback would be good.

almost all have dies brass and bullet selections but I suspect 6mm-284 will be a bit of a challenge looks like its do it your self brass for you. Couldnt find anything but dies for the 22br

Must have been a target and/or varmint hunter. All those are more or less well known calibers in those fields. Given the dies, you can make good ammo for any, even if they are uncommon or unavailable as factory loads.

.22BR is Remington's attempt to compete with the very successful .22 PPC benchrest cartridge.

.220 Swift is still the ultra high velocity varmint rifle leader after 70 years.

.222 Remington was the first of the factory optimum accuracy calibers, still good even though obsoleted by cheap .223 military brass, ammo, and guns.

.260 Remington is a good medium game round and suitable for target shooting at all ranges to 1000 yards, if set up right.

.284 Winchester came out as a short action hunting rifle caliber in Model 88 lever action and Model 100 automatics. It is the basis for the 6.5x284 target rifle round and the super high velocity 6x284 varmint load. Some people are using it for target shooting as is with 7mm bullets in bolt actions.

6mm-.284 is, as I said, a really hot varmint caliber. Same case volume and velocity as the 6mm - '06 but in a "modern" short fat case which has some theoretical advantages.
