Home Forums Reloading Varmint Rifles 220 swift help

I have a like new Remington 700 sf in 220 swift I have shot every factory load and hand loaded to the best of my knowledge it won't shoot anything better than 1.5 inch at 100 yard gets worse farther I can't touch riflings with a bullet unless its 60 grain or more a few 55 no matter what load or bullet nothing better than 1.5 if I slow it down groups open up and seems to shoot 50-52 grains the best but well still not good almost every other gun I owe shoots half of this even with factory ammo I have a 223 same gun not stainless that I handload 40 grain v Max's in an that 1/2 inch TV at the most 3/4 all day I have tryed a second stock three scopes bedded a laminate stock sent back to Remington they sent it back saying it was in spec with a group that was an 1.5 inch looks like they recrowned it still shoots the same it there anyone else out there with a gun like this that has a load for there's or any help for me I'm at a loss

thanks

Try the 50 gr V-Max with Varget or Rel-15 .

Bedding issues are possible.
Quit chasing the lands. Seat 50, 52-53 grain bullets of your choice to 2.680 OAL , start @ 39 grains of H-380 and work up in 1/2 grain jumps. See what happens.

I will try maybe Sunday I have tryed at 2.60 to 2.76 with them never with h-380 with 4064 tho like I said I tryed with factory stock laminated stock and bedded it afterwards I do a pretty nice job bedding I cannot remember trying 50 vmaxs that's worth a shot also I have some I load for a howa 223

The other thing I was going to ask is if neck sizing is bad all my brass is fire formed from this rifle so I have been neck sizing I do have a full length to tho

I have a 220 swift much like yours only a Winchester, it has never shot factory ammo under 1.5".

After a lot of tinkering I came up with W760 (H414) and 55gr Blitzkings seated out as far as possible, it is now the most accurate factory barreled rifle I own.

No neck sizing is a good thing for a swift, but I always use a bushing neck die and a body die to push the shoulder back every 5 or 6 firings

Check the crown-Muddy

Swifty-52, doesn't this throat in this rifle seem awfully long????

In my Swifts, I can reach the rifling with a 50 grain V or BK..

But both are rebarrel jobs..

Yes it does seem long, but Remmys haven't been known for Min tolerance chambers as of late.
The OP stated as new, so wondering if it wasn't bought used and has been partially throated. Most people who buy Swifts haven't been known to keep the speed limit down, and it doesn't take a lot of max load rounds and 4000 fps to throat em a little.
But even if it is throated by going back to max length with a light bullet it should still go under 1.5 with H-380 or AA2700.
If its been back to the factory, it is surprising a bore scoping wasn't requested.

it has been back to Remington it had bout 150 max I would guess down the tube then they shot it the grouping tolerance must be and inch and a half i shot 2 3 shot groups of all my factory ammo so maybe another 50 then tried 150 max handloads this winter I live in Minnesota so its a little cold and snow to do much bench shooting I can match and maybe improve accuracy with my handloads best groups where around 1.25 with 4064 and 53 sierra matchkings and 55 varmaggedons I have tried 4064 h380 4320 varget 3031 4007ssc h4895 people told me to slow it down to 3600 I was mostly loading for 3800 range is I went slower like 3600 it was terrible like 4 inch groups the throat hasn't moved since I measured it after 200 rounds or so

OK, I found that with a 26"-14 Twist tube that mine actually would not shoot flat based bullets as well as Boat tails. Mileage may differ.

You've also been playing around in the same burn rate area on powders and it just isn't working for you.

Since you say that you've used 380, I would go to either H-414 if available, or AA2700 which is available. They are slower than what you are using now.

AA2700 gave me the best results for accuracy/velocity of all the powders you mentioned other than 380, but it wasn't as temperamental at the top end on hot days as 380.

There are loads out there for the Swift that do go the other route as in faster powders i.e. Benchmark, H-335 range, but I wouldn't recommend going there since you are having trouble now.

Might even try a mag primer w/380. sometimes that helps also.

Well doesn't look good for Sunday think I just broke my knee in the hospital now x-rays blah blah blah I have 40 grain vmsx 50 vmax 52 hpbt sierra 50 nosler ballistic tip I think for boat tails maybe one other for powder I got CFE 223 varget 3031 7828 4007ssc 4064 4895 4198 and 748 win I have a good share of bullets to try I may have forgot a few I was hoping to get info from you swifty I have read some from you before thanks a lot this is my first post really I don't know whatever you think is my best bet like I said I've tryed about all of my toughts

Get well.. BEST WISHES!!

+1

like new ?

But if you can't touch the lands with a bullet smaller than 60 grains it sounds like either the throat is already worn, or it was cut wrong.

If you were near me we could scope the throat.... you might want to ask the local gunshop or a buddy with a bore scope to give it a look.

Here is what my Ruger 77V will do with 4064,just about anything else will do close to the same,a lot of it is in the gun,not only the loads.

I agree with you. Sounds throated to me. Some things just don't add up. Think I am out of this one.

Try full length sizing. Sometimes neck sizing creates a situation where the bullets are out of line with the chamber.

Also, check the runout on your loaded rounds. If you don't have a proper apparatus to do so, roll your rounds over a flat surface, such as a piece of glass, and note whether the bullets wobble at all. If there is perceptible movement, you have a die issue.

Clean the barrel down to bare metal.

Run a Q-tip around the crown. If any fibers are pulled off, you have a ding in the crown.

Check to make sure the scope base screws aren't dead-heading against the barrel shank. Make sure the floor plate bolts are tight and not dead-heading as well.

Mount a different scope.

Try these easy steps first, before you get to thinking it's a barrel issue.

Please, please use some punctuation in your posts. They are quite difficult to read, as is. Hope you heal up!

Sometimes it's best to send your problem down the road and start over.

Have you tried a different scope? I have a 700 scope base that won't sit flat, rocks on the receiver, and was one of my toughest accuracy issues to troubleshoot.
