  2. Thanks
  3. Yesterday
  4. I have seen pictures of yours (was going to try to make it to show two weekends ago but life got in the way). I will call them
  5. Sure looks like a Miltech restoration. One can check by calling Miltech in LA and see if that serial # is one of their restorations. I have done this before and they are happy to "own up" to theirs along with the year it was done. This is what they look like.
  6. No idea .. not even close to there.
  7. Comes with display box? Could be a Miltech?
  8. I wonder if anyone has seen this firearm and any opinions on it by the photos.
  9. sharp rifle! looks good
  10. got her back together and cleaned up. more minor issues... no front crosspin, with the sporter handguard my plan is to have my machinist buddy make a short pin that the handguard will trap in place. i have one coming from numrich to measure and cut if needed firing pin stop is also missing. i saw a post here that the LMG ones can be fitted and used. Ive ordered a few of these as well, will let everyone know how it goes lastly looks like mine wore a scope at some point
  11. Picked up two of them, one is really nice. Look to be originals. Will post pics.
  12. Is there any serial # list available for A1098?
  13. Looks like a nice one!

I have done it both ways, but had much better luck forming the cases using the RCBS forming die followed by the trim die (which performs an intermediate forming step) followed by the sizer die. By making the transition in three smaller steps, you reduce the amount stress the brass is under. Also, be aware of the fact that when the case mouth is squeezed down from 30 caliber to 22 caliber, that brass has to go someplace. Part of it goes to lengthen case, which is what the trim die is there to correct. The other part of it goes to thicken the case mouth. If the case mouth is too thick, it can pinch the bullet causing a significant rise in chamber pressure. According to a note RCBS included with my case forming dies, the case mouth should be between 0.010 and 0.012 inch. If it is more than this, you will need to either inside neck ream the case (and then resize it to get the mouth diameter correct) or turn the outside of the case neck.
  16. Someone on another site who has the Quickload ballistics software ran a few simulations of the 5.7mm Johnson for me using 35 grain bullets. His results were: Alliant 2400 COL: 1.690 inch Minimum 11.5 gr - Maximum: 12.9 gr Velocity: 2899 - 3180 fps IMR-4227 powder. COL: 1.690 inch Minimum 14.4 gr - Maximum: 15.2 gr Velocity: 2908 - 3066 fps These are computational results produced by a computer program and are not the result of real-world testing, so proceed with caution. The results I have seen with 40 grain .224 bullets suggests that the 4227 load would be way too hot, so I plan to back down considerably for my starting loads. The burn rate chart on Hodgdon's website suggests that H110 and Accurate Arms #9 might occupy a "sweet spot" between the 2400 and 4227 powders. Please post if you have any results from using H110. I will continue to forge ahead with 2400 and 4227 as I already have them.
  17. Very informative site. It's what ultimately led me here.
  18. Howdy! In the late 1970's I became enamored with the whole thought of a 30 Carbine necked down to 22 and firing a fast bullet. I wanted a gun like that from the first moment. And in late 1982/early 1983, I found on Iver-Johnson M1 Carbine chambered in 5.7mm Johnson in a gun store in Batesville, Arkansas. The stamp on the receiver indicates it was made in Plainfield, New Jersey. It came with a set of RCBS reloading dies and a small quantity of loaded ammunition. The dies have a date code of "79" stamped on them which I take it to suggest that they - and probably the associated rifle - were made in 1979. It took two rounds of the ammunition that had come with the gun to realize it had been loaded way too hot and the other rounds were disassembled, the powder discarded and the other components salvaged. It also became apparent to me that the cases had been formed by running 30 Carbine cases into the sizer die without the use of any forming dies. It didn't seem to me as if that was good practice and so I shelved the gun until I could get some information about it. I later discovered that several reloaders formed their brass in the sizer and reported no problems. In 1986, I was in Pine Bluff, Arkansas, and the owner of a gun store there had a copy of an old Pacific reloading manual that had charges for the 5.7mm Johnson in it. At this time, I also had the chamber cast and was told the bore was 0.224. I would later have reason to question the accuracy of this cast. The Pacific data also proved too hot for the gun. I was getting the usual pressure signs of primers backed out of their pocket, flow into the firing pin channel and distortions of the markings on the case head. I once again shelved the gun. By 1993, I had landed in Texas (I think of it as temporary exile) and had purchased forming and trim dies from RCBS to go along with my existing set of reloading dies. I also had gotten the load data from Cartridges of the World. I also received some additional reloading information and technical data from RCBS and The American Rifleman. At that point, I tried reloading but stepped the starting load back to 11 grains of IMR-4227 with a 40 grain bullet to be sure I was below the pressure danger zone. 11 grains would not cycle action, but 11.5 grains would. Still performance was anemic and accuracy poor at this load. I also tried Hercules 2400 and IMR-4198 powders as well and had no better results with them; as a general rule, any powder that would cycle the action produced signs of excessive pressure. Since then, I would revisit the cartridge occasionally and try to work out what was going wrong. With the arrival of the internet, I was able to communicate with other reloaders, but until recently was unsuccessful finding anyone who had any first-hand knowledge of the rifles or the cartridges. Through the Iver-Johnson pages on, I eventually got connected to Edward Rice Johnson, Col. Johnson's son, who was able to provide a considerable amount of information about the rifles and 5.7mm cartridge and led me here. One of the things Mr. Johnson pointed out was that some of the commercial manufacturers used barrels that were either 0.223 or somewhere between 0.223 and 0.224 (call it 0.2235) and that for these barrels, a 0.224 bullet might simply be too big. A subsequent cast of the chamber and bore revealed 1) cases formed using the RCBS form, trim and sizer dies matched the chamber very closely, and 2) that the bore of the barrel was "indeterminate", which upon closer questioning of the gunsmith means it was neither 0.223 or 0.224. I take it this means it is one of the barrels I have chosen to call 0.2235. Rather than asking my cartridges to swage my bullets on their trip down the barrel, I have obtained a quantity of Sierra 0.223 bullets and will embark upon loading those starting later this year. Sorry for the long introduction, but I wanted you to know where my 30+ year long adventure to load this cartridge has taken me, If there is anyone out there with experience reloading this cartridge, I would appreciate any help you are willing to offer. Thank you.
  19. Here is the data on JSAR #8960 as it came from the factory: Received from Cranston arms 2/28/42 Stock #2 Bbl #7294E Hammer block #8186 Hammer #8945 Bolt #0024 Locking cam #5090 Extractor #7508 Firing pin #8436 Magazine #A2887 Transferred to NPC 3/4/42 You have a type 3 rear sight. These were typically painted with a black finish (to cover braze marks which did not take the blackening (actually Dulite) finish. I have never seen a reproduction type 3. The hole on top of the radiator section of your receiver is not supposed to be there
  20. hi everyone, i picked up sn 8960 this weekend. can i get the serial numbered parts list for this rifle? i havent had much time to go over it yet, but the hanguard appears commercial since it lacks the cutout for the front cross pin. otherwise the barrel appears to be in fair to good shape, but my mainspring is too short at 11 1/4". I see Mr Scott hasnt posted in a while, does anyone else have one for sale or should i pm him. id like to have his dvd as well. Im attaching a few pix i took with my cell phone, i can post better photos later. i think iread somewhere that all blues rear sights are repros, is this correct? has anyone seen the small hole in the sheet metal barrel jacket shown on mine? i havent seen it on other rifles ive looked at online. anyway im sure ill have more questions, thx for keeping this forum up, theres really no other good info on the web ive found lear couple more pix...having trouble uploading....
  21. Here is the data on JSAR#400 Received (at JAMCO) from Cranston Arms - unlisted Stock # unlisted Bbl #848E Hammer block #0365 Hammer #0619 Bolt #1181 Locking cam #220 Firing pin #847 Extractor #805 Magazine #0663 Transferred to Netherlands Purchasing Commission 10/1/41 This is an early JSAR which might have possibly made it to the Dutch East Indies before they fell to the Japanese later in December.
  22. Still hoping for any information you might be able to share. thank you chris
  23. Congrats, It looks very nice.
  24. Been looking for one for awhile. Just received this one today.
  25. Were you the same person that sent me info similar to the above? Did you receive my replies? Or is yours an entirely new situation? Ed J
  26. Will do !
  27. Earlier
  28. Was looking on calguns today and found a 1941 johnson automatic for sale. Nice looking rifle but out of my price range. just in case someone here is interested.
  29. I bought a new barrel for the 5.7 spitfire and got a set of new dies cheap with it, has a Williams front sight on it with a 1-16 twist. would like to know if the forming die is the best way to form 30 carbine to 5.7 or will he dies work just as well? i ran 100 carbine cases welll lubed through the sizing die and had 6 crack at the neck, all the rest match up perfect with the chamber cast I made. anyone have reloading info that works well with the 1-16 twist barrel? I have a bunch of .224 35 gr. And 55gr Bullets, throat is long enough to run 70gr single fire but twist is to slow for probably much more than 45 gr. i wanted this caliber to get my grandsons into highpower without all the noise and recoil, great step up from 22lr. looking for loads more for accuracy than speed.
