Heavy bullets in 220 Swift

[Hotshot]

Looking for advice and starting loads. I have an 8 twist barrel begging to try some heavies. Not much information out there.

 

[Gary in MD]

My Swifts are 12 & 14 twists, so I don’t have exactly what you are looking for. But the Swift is basically the same case capacity as the 22-250 imp and the 22 CM so you could start with medium loads from those two with heavy bullet data.
I’d be looking at H4350, N160, Staball6.5 and similar burn rates.
I’m using the Staball6.5 in my 22-250 8 twist to shoot the 77 TMK and it’s working fine.

I have some 77 grain Sierra bullets and IMR 4350 on hand so I thought I would start there.

I used to reload for 5 swifts and now I'm down to one. I never tried any heavies, so I am of no help to you. I'll be watching for your results.

Howdy !

I shot a 28" 1-8 barreled varmint rifle, chambered in my
" .22-35 Remington " wildcat. Case capacity was between that of a stock .22-250 and that for a .22-250AI.

I shot Hornady 75 "A"-Max in it exclusively, for both varmint ( groundhog ) and target work.

In my gun/my loads...AA3100 shot best, outperforming H4831, VV160; and VV-560.

The accuracy/ field load I selected was loafing along @ 3,400fps when I used FED LR Match; along w/ great accuracy. Sustituting to shooting FED LR Large Magnum Rifle Match increased vel to 3,500 fps, but groups opened up a bit.

Ools...hit transmit on previous response early, in-error.

GaryinMD's input sounds spot on, to me.

I am getting ready to have my next .22-35 assembled w/ a long Bartlein gain twist barrel; for propelling Hornady 55SX to great speed.
I am switching from WW760 to 6.5StaBal, for this application as my new anti-groundhog rifle.

Had the Ole gal out yesterday after receiving some once fired brass from a board member here. I have the same situation as Gary,slow twist rifle. I always thought factory Swifts were 14 twist,but yesterday while cleaning it occurred to me that the cleaning rod was spinning faster than my 14 twist 222 and 222 mag. Didn't think a lot about it as I was pressed for time. Later I did a search and noticed that Ruger may have made the 77V with a twelve twist.After work today I will definitely measure it. Anybody else here checked their old Rugers twist? She still shoots well with the 55 vmax but when it's time for a new barrel I may switch to a faster twist. Currently the idea of the 53 vmax working has me hoping it is a 12.

I dont know what to recommend charge wise for a straight swift
I have a 220 Sw AI and use 80's and 85.5's launching them at 3650 fps
I could throw out my charge weights but it would be pretty irrelevent being approx 5 grains water capacity difference between the 2 cases.
FWIW - I use IMR-4831 and Re-22 powder
Leaning heavily to Re-22 being the most accurate (skip Re-19 - tried it, not accurate enough)
---------------------------------------------------
If you want to reduce what I use by at least 7 grains to start with for safety, I can look at my notes and let you know my load.

I have one with a 1x8 and it will take up to 77 gr Bergers. with no problem. I have not run any 80s yet.Mine is on a Borden action 28 in tube , by Speedy Gonzales. Here in San Antonio.He said i was crazy buy it shootes

Curious on why he didn't like your choice?
Because of the poor quality of brass available? That it's not as accurate as a ppc maybe?
I guess Speedy isn't varmint hunter.
For the record, big fan of the mighty Swift here.

77 gr Sierra 40.5 gr IMR 4350
200 yard group
Some primer flattening
I can’t say I was real disappointed but I sure wasn’t elated

 

[Hotshot]

Then I tried the same bullet with 40gr H4831 no flat primers
Now I’m excited

My dad bought this model 70 in 1947 when he got out of the Navy. One of his best friends was Ed Reiten a great shooter and remarkable machinist. Ed blue printed the action and trigger and it still uses that same trigger today. This is barrel number nine and still going strong.

What is the case capacity on the .220 AI? How long Is the barrel? 3650 is impressive with the 85.5’s

with that load I'm using 45.0 grns of Reloder 22
I don't remember the total capacity but it has more room as I use 47.0 of 4831 for 69 TMK's
30 inch barrel
-----------------------
6-7/8 moa elev. needed with the 85.5's for 600 yds should explain how flat it shoots due to velocity

I am running a 30” on 22 creedmoor N565 3355FPS with the 88’s 3500fps was starting to show pressure

 

[dakor]

77gr Sierras with 44gr of H-4831 are money out of my 8 twist 220 swift. I would start at 40gr and work up. Skip the 4350 you are going to want a slower burn rate for the heavy bullets.

88 ELD-m???
I could not get them to hold together, (Hornady is like that)
and I was not going to load down just to use them when I can use 85.5's and keep speed up
I would say my case capacity ///or at least my loads are 5 grains over a standard 220 swift
With N565 being a high energy powder , have you tried N170
I will say I tried VV powder once in a 6x284 (N-165) and it shot terrible
I went to the stanby, H1000 and all was well,
I stuck to H1000 and Reloder powders ever since
Sometimes I think VV is a lot of hype

Yes, 8 twist. So far so good - no blow ups but only 350 rounds down the barrel
