Hello to all.

I am in the market for the parts to make a sliding tang safety for an O3 Springfield. If anybody has such and wishes to part with it you can send me a PM email. If I can't find the parts, does anyone have a drawing of these items in order that I could build one. I've never seen a O3 that has been converted to such; I've only seen pictures. I've got a little 18" barreled 7x57 Manlicher (I know I misspelled that word) built on a O3 action that is almost finished, it has been test fired but it isn't too far along to make this addition.. This addition would be the finishing touch that it needs.

Thanks,

Mashburn

mr. mashburn ... no, i haven't received a pm or email with the your 17 information ...  i do think we are at war with computers ...

and the computers are winning ...

thanks for the comments and help on the 17 project.  i am making some progress ( got barrel ordered.. 9 twist )  but have some other concurrent projects that i am working on.

i suppose we need to start further 17 conversations under a " 17 project " thread ... just in case we could get anyone else interested in such ...

i am not worried about mj bullets, as i will likely only shoot lead bullets in it.  so i am thinking a 15 grain capacity would be fine ... somewhere in the 25-20 or 38 special brass range.

i do have about mj 3000 17 cal bullets but they are extra long, and i doubt that 9 inch twist would work.

thanks again and i will report back when i get further along with the lead 17 project.

Hello Ken,

I sent you a PM with this information, that I doubt that you received, so I will send it this way. 

1. Saunders claimed he got better accuracy with Remington bullets

   A. we found that v-max and ballistic tip bullets shot much better, but the Remington's(25 grain HP's)

 were much cheaper and shot almost as well. ( At the time we were buying Remington .17 bullets for about 68.00 per thousand)

Shortly after 2000 Remington quit making their own .17 bullets(they said their swaging machine wore out)  Remington then started buying their bullets from Hornady and quit selling .17 bullets as components, they are not a, v-max Hornady or ballistic tip bullet. So we quit Remington.

2. Sanders  said he had no luck with 4198 powder. This is the most accurate .17 powder that Me and my brother-in-law ever used.

  He said his .17 built on a Martini action in .17 Bee started showing pressure signs early. My 5MM Remington action must be stronger than I thought, with heavier loads in my improved Mashburn Bee I have not had pressure problems.(In other words it hasn't blown up yet)

In the years he started experimenting with these little boogers,  barrels were still mostly cut-rifled barrels and fouling was a problem. The rifle that he described that had the Myrtle Wood stock and sold, I talked to the man who bought that rifle for his wife and said that two or three shots and it was fouled.

He was one of the founders of .17 wildcats and shared a lot of information with me that greatly speed up my .17 caliber knowledge process .I have a lot more that I would like to share with you but I'm very tired of typing.

Hello RC,

It stormed and rained all day Friday, so I didn't make it into town to the post office. I mailed your stipend today(Monday).

Thanks again,

Hello Ricin,

I thought I answered this last night but I see that I didn't. That is a great deal for me. You don't have any idea of how much I appreciate this. If nothing happens tomorrow I will get your request in the mail, if not I will do so Monday. Now you have two replies, I answered the one under the blog article that I commented on.

Hello Ricin,

I sent you a PM stating that I had received the safety kit. If you will tell me what you've got in it I will send you payment plus postage. I've rounded up a slitting saw and when things calm down around here, I'm going to install the safety. I'm going to anneal the complete shroud and then heat treat again. I have a heat treating furnace. I'm going to quit trying to sending PPM's because most of them never go out evidently.

Thanks,

Mashburn

Hello DB404

I understand your problem with the swing safety on a 98. O3's don't have quite as bad a problem, the trigger is farther back and the bolt shroud is longer. I have looked on the computer auctions for years for the type of safety that I referred to in the article and with no success. The sliding tang safety kits were still being manufactured up in the mid 70's but I can find any information since. I have a very early Browning A-Bolt rifle that has a very good sliding tang safety and that was the only thing that I liked about early Ruger Model 77 rifles. I have close to 30 custom rifles setting around here waiting to be finished and I'm 76 years old. I want to finish them while I'm still on top of the earth. I fired this particular rifle about 15 years ago and then I set it back to wait for the safety mechanism that I've been looking for. By using the swing safety, I can finish it and move on to something else. It will be located close to what the Model 70 Winchesters are. As far as moving triggers back and using different brand triggers in different rifles, all is possible. I have the tooling and knowledge to build about anything, but the patience is growing thin. You mentioned Roy Dunlop ,there was a true gunsmith & craftsman. If todays gunsmiths had a little of his knowledge it would be a great asset. Today all that people want is black plastic. And you hear people talk about building a AR, when all they did was stick some parts out of a box together. I'm glad to hear from someone who apparently has some knowledge of custom rifles.

Hello Ken,

First of all-did you get the .17 caliber shooting book, that I sent you. I sent you a PM email and haven't heard back from you. Of course, when I send Pm emails to forum members, half of them never arrive. I mailed the book first class with a tracking number. Let me know if it has arrived. I don't know anything about the Saco trigger you mentioned. Never had any dealing with one. When you mention trailing hounds you bring back a lot of good memories. I kept a pen full of fox hounds for years. I still have some of the races recorded on tapes around here somewhere. I wish it was possible to bring back those days.

.... i had that Sako trigger with side safety 98 Mauser on my commercial FN Mauser coyote rifle.  trigger was great, ( set and forget for 30 years ) ...   safety i felt about as reliable as the 1960 Rem. 721 side safety .... never sure it was securely on and was always riding the thumb button to see if it was still on safety ....  kinda like carrying an 870 shotgun ...

no problem for coyote hunting, i just never chambered until just before the shot.  i could chamber a round just as fast as trying to figure out a swing safety.  note that although coyotes occasionally tried to eat my trail hounds, none ever set the bar the same height as my throat  ... although out at 2 am sitting in a snow bank with a squeaker call i have had a few moments of reflexion ...

maybe one could increase the detent on a side thumb safety, maybe get an action like a good pistol rotary safety ... can you put a Beretta 92 safety on a Mauser 98 ? ...

just ramblin  ... ken

It looks like you’re dialed in on the Winchester side swing safety. Have one of that style on my .404 Mauser 98, and can say I don’t really care for it as unless one has thumbs about as long as a full grown gorilla’s is, it slows down the act of establishing a firing grip on the rifle when in a hurry. Originally I had been going with a sliding tang safety but then during the building of the rifle I got to thinking that a slider might weaken the wrist of the stock so changed my mind. My bad. The sliding tang safety when done right locks the bolt down, which is desirable in a hunting rifle and is mandatory in a rifle to be used on things that might argue about their being followed in the bushes. They are Very fast in use and the only thing I’ve found in that same ballpark are Browning designed lever guns (Win 92 & 86 are the ones I have) fully loaded and with the hammer pulled back to the first position so it doesn’t rest on the firing pin. For a tang safety on the Model 98, Sako made an after market trigger (which can occasionally be found on the auction sites) with a thumb tab which stuck up on the right side of the tang. Custom gunsmiths will add a tang extension to the wrist of the stock and run a connecting piece from the trigger to the new thumb piece on the tang, hidden under the tang extension. Whether or not a trigger made for a Mauser 98 can be modified to fit an ‘03, I have no idea. IIRC, in Dunlop’s book on gunsmithing, he has a picture of an ‘03 trigger fitted on a ‘98 Mauser in order to move the trigger further to the rear within the trigger guard.

Hello Ken,

I got your .17 caliber shooting book copied today. It's in a big manila envelope and ready to ship. I think, I have your address, but not for sure. You might want to PM me with your mailing address, just to be sure. I'll ship it Monday. You are going to enjoy.

Hello Bud,

I agree with you. That is one conversion, that I think that, I would want to back away from the firing line when that one was being fired. A person has to use a little common sense.

Thanks for your response,

Mashburn

I've fired my little high pressure .17 enough that I have faith that they are safe. When Dick Saunders, from Iowa, started this with the little actions, he first said that he didn't know if they would back up a cartridge head as big as a 32-20 or not but after a couple of years he said they would take it with no problem. I make all of my extractors and have experimented with two different types and they both work very well. Of course, there is a limit to all things. There is one thing that I will not do without, and that is I will only use the small Remington bench rest primer in this cartridge. I imagine the peak primer pressure is quite high.

Somewhere I have the direction from Calhoon, in Harve, MT, about their conversions. Since mine are centerfire, I use an 1891 Argentine Mauser extractor in the new bolt head. Since mine are low psi, I only calculated total bolt thrust to see if it was safe.

Hello Ricin,

I also lap the locking lugs. I can't remember but I think the 5MM actions are longer that the .22 actions. I dug out some of the information, that I told you about, pertaining to the strength of the 5MM actions but I haven't found the Remington material as of yet, but it is here some place. The SAAMI specs. for the 5 MM cartridge are-37,000 psi with a maximum product average of 42,000psi and a maximum proof pressure of 62,000psi).There all kinds of gun magazine jargo about why Remington quit manufacture after only 4 years, but according to Remington, the reason for dropping was pressure and a possibility of a case head rupturing even with the odd ball extractor. They were never able to develop an extractor, with any kind of cut in the bolt face or the barrel, with out having case head ruptures. They said it was dropped due to safety issues(a possibility of a lawsuit) They also said tooling was destroyed. The info also included action material and I think, I'm not completely sure, the heat treatment of such parts. I'm going to keep digging until I find this info, it's here someplace. 

Thank you for the information we've shared,

Mashburn

Bud, The only documented problem I have seen is from not lapping the nine locking lugs into the action. When 22LR's, just one will hold the head space. With the greater recoil impulse, they need to be lapped so all nine are in full contact. Ric

After I moved to California, an infrequent shooter at Windhill showed up one day with a Remington 580 action converted to a .17 on the .30 Carbine case. The action and cartridge worked well, it was devastating on starlings. I thought the cartridge was good for small varmints up to fox and coyote, however I was weary of the action.
