6.55X55 M1 Idea

I was thinking today how great it would be to have a Ljungman rifle and the likely hood of that ever happening is 0% however the .308 M1 topic made me think about converting an M1 to 6.5X55 SE. I don't know if it is possible or not, I know the case heads are different so it would probably be difficult. But I bet it would be extrememly accurate. I know they rechamber M1's in .308, .260, .243 and some even more exotic calibers.

Sorry just thinking out loud I guess.

Take it easy everyone and have a good weekend.

Why is the possibility of finding a Ljungman rifle 0%? I still see them from time to time at gun shows for around $500-$600. If you just look around you should be able to find one in decent condition.

I'm not sure if a conversion of an M1 in that caliber would be feasible. You could do a .260 conversion and have similar ballistics to the 6.5X55.
Interesting idea though.

I had one rebarreled to 8MM Mauser, very reliable and accurate, also very loud! Other caliber options are 7MM Mauser, .270 Winchester, .25-06. .280 Remington.

Go ahead and think out loud , if ya need it in 6.5 there's the .260 Remington the 6.5-06 and the 6.5X57 for starters . Now for getting the barrel made ............... that might be a trick .

"Go ahead and think out loud"

I second that. I think out loud all the time and Jack can vouch for that. Being a .243er, I had thought of doing one, but there's the matter of getting Roland Beaver to barrel it and do all the other work. I could see me running up a big bill in a hurry that way.

As to the 6.5 idea... like Jack said, "if ya need it in 6.5 there's the .260 Remington the 6.5-06 and the 6.5X57 for starters . Now for getting the barrel made ............... that might be a trick." I noticed the 6.5-06 and noticed mention of .270 Winchester in another post. IIRC, a .270 is just that but I'll have to look it up to be sure. I do know for sure from reading that a .270 case is a .30-06 necked down to .270 caliber. But, a 6.5mm is a .284 diameter. If my info and logic are correct right now, it seems it'd be easier to neck a .270 case up to 6.5 than it would be to neck a .30-06 case down to it. I don't know because I haven't worked up cases and you could run into issues with the shoulder angles and a couple of other things... just me thinking out loud.

The 6.5 uses .264 diameter bullets. It is smaller than a .270 which uses .277 diameter bullets. The .284 diameter is also known as 7mm. I just had to clear that up, sorry.

Thanks for correcting that( however why is this cartridge sometimes called the .256-06? I see the two being used interchangebly but I thought they where two different cartridges)

I was thinking the same thing about .6.5-06 Would actually be the easiest being already based on the 06 casing. I really like the 6.5X55 cartridge I already have a couple of mausers in this caliber and its a personal favorite of mine, plus its allready a known military cartridge not a wild cat. I don't really have any experience with the 6.5-06. But im guessing it performs similairly if not better than the 6.5X55mm with the longer case length. But a 6.5 buller in a -06 case might be the best of both worlds. I have never heard of an M1 chambered in this caliber.

Definitly something to think about!

Oh the reason I will never find a Ljunman, is I never see them for sale. Last time I saw one for sale was 10 years ago. I see Hakims from time to time in 8mm.

Thanks everyone, by the way thinking out loud was kind of foolish thing to write. Its not out loud if I am typing it on a computer.

The .256 designation I believe comes from the British. I am not 100% sure about that. I know that the British called the 7X57 Mauser round a .275 even though it uses the standard 7mm/.284 diameter bullets.

I think that a conversion to 6.5-06 would be interesting, however it would be pricey since it would require a custom barrel. Of course so would a conversion to 6.5X55, plus the bolt face would need to be modified. I wonder if the en-blocs would even work with this round since it has a slightly larger body and rim. Something to think about.


If I still had a Ljungman, I would sell it to you, but I sold it a few years ago. It was a nice well made rifle in a good caliber, but I just couldn't get used to its odd operating system. I have never gotten "M1 thumb", but I did get "Ljungman thumb". Anyone who has used these rifles or the Hakim will know what I am talking about.

And now I wonder how I got that mixed up. Now, my whole logic is blown away, but better to be sure of the facts because it sure wouldn't have worked the way I was thinking.

Now I see how I got confused... got the "mm" crossed up with the English decimals... I really should quit posting when thinking of numbers late at night like that.

I was able to get 8-6.5X55 to fit in a M1 clip albiet a little tightly. But they fit.

Ljungman thumb could be really bad. I have operated a few hakims but never managed to hurt myself, but I know what you mean about there operation, very strange system. Actaully a Hakim in 8mm would be the most economical to shoot of all of these rifles. I have only seen about 4 of them for sale though in last 5 years. Who knows though maybe I will find a Ljungman someday, I wonder how reliable they are with the gas impingement system and all.

Go figure I got M1 thumb once at my first John C. Garand Match! It was only the second match I attended and about the 3rd time I ever fired an M1. I was loading a single round in the chamber with my left hand and pushing down on the follower with my right index finger while holding the or rod handle back with my middle finger, my middle finger slipped off the op rod handle and released the bolt right onto my left thumb which was still pusing a single round into the chamber (I wasn't using a sled, and I know about the possibility of slam fires) anyway that was the last shot of my first string so I had to shoot the rest of the match with a bruised thobbing thumb. I didn't have breakfast before the match so I felt pretty queezy and gross.


take it easy everyone

No. A 6.5mm is .265 diameter. 7mm is .284.

edlmann, I heard 'em the first time. And FWIW, when I typed that it was late at night and I didn't have the manual with me. Maybe you didn't see my last post where I said I was going to quit trying to post numbers from memory that late at night.

I did a Garand in .270 Win....Ammo cheap at the WalMart, and shot better than a laser beam. Nice recoil with Federal 130's.

Should be a fun project but a bit pricey unless you can do the barrel work yourself. The 6.5X55 is a fine round.

I thought I'd resurrect this thread because I recently found out that a company does this sort of work. They can convert a Garand to pretty much any rifle caliber up to and including the .458 Win Mag (yes, you read that correctly, WOW!!). Its not cheap, but if anyone can convert a Garand to 6.5 Swede, they can. If you're still interested, and you have the money for it, you may want to contact them.

Anyway heres the link:
