Thank you DANTHEHUNTER. If you read this string, there is only one thing to say....all the posters who bad mouth the 220 Swift have never owned one, never fired one and never run one through a Chrony. I have fired thousands of bullets through my HVA, Shilen barrel Mauser without the slightest "erosion" problem at 4000+ feet per second It is the finestvarmit rifle I have ever owned and at 60 years, I've owned a bunch including 2 250's. See Pic attached.......now there is the ultimate varmit rifle IMHO!

Don't use those factory ammo charts tell you how a certain cartridge preforms. That is just their stated ammo not what it is capable of. The .220 swift has 3.18cc case capacity while the 22-250 has 2.75 so yes the swift can be loaded hotter then the 250. They are both very good caliburs and both preform well. I have had both and I chose the swift for a number of reasons but the main one wasI love loading for it.It has been the most compared to varmit rifle years. I think if a guy had a .22LR ,.220 swift, 30-06, 45/70 and a 12 guage you would have all the long term ,most talked about , the ones everyone is trying to improve caliburs in the buisness.
Getting back to the subject, There are alot more factory ammo offerings for the 250 , hornaday's 40 vmax rounds are pretty awsome out of the swift, 4200fps while the 250's are 4150fps. I can take that same bullet and push it at 4400fps(Accur 2520 42 grain) loading it on my swift ,but I could only get about 4200fps(Accur 2520 38.5 grain) out of the 250. So there is some useful info for ya not based on the fact I own one or the other.But like I said they are both very good rounds. If you want to know I have a Ruger M77 MKII target .220 swift, andhad that same rifle in 22-250.Good luck !!!!!
