    Anyone have experience hand loading 220 Swift. I got some 52 grain Sierra BTHP. I have H-4895 & 380 at the moment.

    My Hornady #3 has data and a blurb for it. I have no personal experience with it, or anything like it. I'll look at the manual later and post anything if it looks like it might help you.

    I assume you're not new to loading, just the 22 Swift? Also, as a general rifle comment, I really like the Lee Collet Sizer die. I don't know if they make it for the 220, but it really makes things easier, more accurate, and extends the life of brass.

    Back in the day I had a terricly accurate Ruger in 220 swift. The Swift is an overbore round, means it will prefer slower powders for best vel. So while those powders will work, I used to shoot a lot of 4895 & 45-50gr bullets, something a bit slower like RL15, VV150, H4350, etc, will give highest vel w/ exc accuracy. If you want a ball powder, AA2520 would be a good choice.

    Not new to hand loading, just the 220. I am going to order some 40 grain bullets, and will definitely look for some slower powders for the dog town loads.

    For the light 40gr, 4895 will actually work fine. I can't find my old data but 4100fps was easily done. Lyman likes 39gr as max.

    One of the things Hornady notes is that some fragile varmint bullets, when driven to 220 velocities, in a faster twist, can fly apart due to centrifigal force when they leave the muzzle. Fred will know the specifics, but I would look into that before buying bulk quantities of bullets for it.

    Mine has a 1:14 twist. I will look into that though. Thanks.

    Yep, stay away from anything made for fragmentation. Most 220 have slower twists, but above 4000fps, lots of bullets can come apart. I had it happen several times running 45gr @ 4100fps. That was back in my early days reloading, thoughts of burning bbls out & case life took 2nd to hitting max vel.
    I would like to build another high vel 22, a 220swift is great, but then a 22-250AI is about the same vel in cheaper brass & it's just diff enough.:supergrin: I would probably use the higher possible vel with heavier match bullets, like the 52gr-53gr. You'll get better bbl life & probably accuracy, but you won't break the 4000fps barrier.

    I've been using IMR 4350 and IMR 4895 for my 220 Swift and it works well, I stick to the 50-52 grn bullets. The lighter bullets go faster but as Fred said, they can tend to fly apart and also will burn out your barrel quicker. With a 1:14 twist you'll want to stay with the lighter projectiles. Also as a sidenote, a 220 can be VERY load picky. You might have your charge perfect but the COAL off and it won't group. I've found that loading for the higher-velocity rounds like 220 can be very frustrating to work up a load for if getting to the range with loads to test is a problem.

    Plus fouling is an issue w/ the ultra high vel rounds. Keep the bbl clean, it will group better. The reason I would go 22-25AI would be the shorter powder column would lend itself to being less picky IMO. I would also want a 1-10, but then I have no use for bullets less than the 52-53gr match pills. Maybe my next precision rifle project. Just get a 22-250 & have it rechambered.

    My 220 Swift rifle likes Speer and Sierra 52 grain bullets. It does well with Remington 52 grain and Winchester 53 grain bullets but it does terrible with Hornady 53 grain bullets. The 50 grain Noslers work well but not 50 grain Remington bullets. The 55 grain grain bullets are usually only so-so in it but can sometimes be very accurate. I suspect they might be at the edge of maximum weight for the rifling twist rate.

    Best of my 220 Swift loads.

    IMR-3031 with 50 grain bullets.

    IMR-4064 with 52 and 53 grain bullets.

    RL-15 with 55 grain bullets. (37.0 grains has been best)

    H4895, IMR-4895 and Varget work well sometimes.
