*+*+*+*+*+*+*Here is my completed conversion*+*+*+*+*+*+*  1. This is an exploded view of my modification. In order from left to right, you see the modified firing pin/striker assembly, bolt tube, shell holding bolt cap, .32 ACP casing, new breech plug/chamber, and Lehigh vent liner.  2. Another view of the same, from the front of the rifle.  3. Left to right, Lehigh vent liner, new breech plug, and .32 ACP casing. The breech plug installs into the rifle with your standard Remington breech plug wrench. The .32 shell has the primer flash hole reamed to 5/64 inch and uses a Small Rifle regular or Magnum primer.  4. Left to right, new shell holding bolt cap with a .32 ACP inserted, new breech plug view from front, and Lehigh vent liner.  5. Pieces mated together with casing seated to full depth.  6. Firing pin/striker assembly closeup. This pin is retained by the lock nut and is easily serviced in the event of firing pin damage.  7. Firing pin/striker assembly side view.  8. Completed conversion on my stainless .54 cal, bolt open, view into chamber.  9. My stainless .54 cal., bolt open.  10. My stainless .54 cal., bolt closed! I tested this conversion in .54 and .50 caliber with great success. There is absolutely no blow-back fouling into the bolt mechanism. The cases extract as easily as they go in. There is instantaneous ignition with black powder and all substitutes, even the finicky Blackhorn 209. The conversion process involves shortening and machining the end of your firing striker. The bolt cap must be indexed and tapped into place with a plastic mallet. The .32 ACP case was chosen because of its diameter. This way you can continue to use the tools that came with your rifle. There is a possibility you may need to trim your cases and / or face the breech plug for correct headspace clearance. Understand this conversion is NOT for smokeless powder. This conversion was designed to eliminate the filthy job of disassembly and cleaning of the bolt after every use. What do you think? Who wants one? |

I don't have a 700ML any longer but I compliment you on a nice job. Any trouble at all with the shell holder cap working loose?

No, It's a press fit.I had to tap it home with a plastic headed hammer. I bought some 94/6 Lennox HVAC solder in case it didn't fit that tight.I stumbled on to it while viewing their website. It has a tensile strength of 15,000 psi and it melts at 430 deg. F. Thant's as good as silver braze without the high heat. I thought I'd go this route with my 700 ML instead of canibalizing a 700 CF.

Wayne, A friend of mine made up a dozen or so of these. His master machinist buddy tweaked our proto type and so far I,m tickled . You need to realize that this would be a self installed upgrade except the rework of the firing plunger. You would need to send that to him I suppose. These 700 ML's are not Identical so we took measurements on six that we have and tried to get into the ballpark with the breech plug dimensions to allow the fitting of the bolt cap engagement. On the .50 cal's so far none of the brass needed trimmed. On my .54 they did by .015. But there is no blow back. On the .54 I saw some on two cases that I trimmed too much. Since you're considering a .45, the breech plug protrusion will have to be a different dimension.I'd say that if you are an old reloader like me, have access to a case trimmer and can do some mid-level mechanical skills,this may be the way to go.

Is the arrangement forgiving of slight misalignments of the casing to the breech plug when feeding them in?

Underclocked, Sure it is. If you look at the photos of the BP,you will notice it has a slight chamfer and the bolt nose/shell holder actually engages the case body not allowing it to droop downward as does the 209 primer in the Savage. The flimsy so called rim on the 209 was never intended for this purpose.

Blackhawk, I'll have to get you a contact phone number and address for my friend's gun shop. Are you able to remove the firing plunger from the bolt? I don't think that he will need the bolt body. The other parts you'll need to install. The BP may need to have additional material removed from the unthreaded portion of the shoulder. Can you procure .32 ACP brass or will you need them supplied to you? The price is around $180.00 + S&H.

mountainam, I can dissassemble the bolt and striker. The brass is no problem either. Will he need the barreled action to fit the parts or is it a drop in fit?

The Remington 700 ML /.32 ACP conversions are being facilitated through :
Denny's Sporting Goods
1899 Brookfield Road S.E.
Hubbard, OH 44425
Denny's phone number is 330-534-3707. He would like these parts to be a drop-in however, the dozen or so that have been performed had to have the breech plugs tweaked for the cases to seal. So he has informed me that it may be better if you send the entire gun to him.Give him a call he's a great guy and I'm sure you and he can discuss what level of fitting that you can handle yourself.I just talked to him. Give him a call tonight and leave him a message.

Thanks, I was thinking about doing a conversion for .25 acp cases. What advantage would the .32 case have over a .25? Maybe seal better?

The .25ACPs aren't a whole lot easier to handle that those darn 209s. For me,the .32ACPs seem to be not too big or not too small. There are more manufacturers of .32 than .25 ACPs. If you go any bigger say to a .380 then your hex head on the BP goes away and you won't be able to use the wrench that came with your gun. The larger diameter of the .32 seems to not leave a whole bunch of build up in the breech plug like the Savage does with it's 209s.There's always another way to do anything.As you probably seen there have been fellows that used the Savage 10ML shell holder assy. on a Remmy 700ML bolt.That will work with a .25ACP. It actually holds a .25ACP better than it holds a 209 primer.

I have a stainless 700ML that I converted to a Savage shell holder. It works very well and has no blowback but I would like to use milder and cleaner primers. The fit of my primer is critical so I don't know if those 209 primer adapters that take rifle primers would work or not.
And I know I would end up loosing those adapters every time I reloaded in the woods.
I think the casing with a rifle primer is a much better idea than 209's. At least for non smokeless loads anyway.

Post by mountainam on Nov 1, 2009 7:58:50 GMT -5
That sounds like a no-brainer to me. You're 85% done already. The 209 adapters will not work.I've tried them. And at $2 apiece,you would not want to misplace any. It's a little more work to find the .25ACPs but I'd go that route in your shoes. You may want to drill the flash hole in the cases out to 5/64" to get everything it has to offer. You would still have four intensities of prime from small pistol and mag to small rifle and mag. Drill your BP to match the casing and then clearance drill to a depth that leaves you with .060 to .080 for the mouth of the case to swage into. Mic your cases first.Don't go by any SAAMI dwgs. After using both 209s and small rifle,I believe the 209 has no business lighting off anything but shotgun powder. If you do any metallic cartridge reloading you probably know that the lightest primer intensity that will light off the load generally will give you the best accuracy.

Thanks, that sounds like a plan. I already have primed .25 cases. Do you think the small pistol primers that came loaded in the cases will be enough?

Blackhawk, Without knowing the specs on the breech plug it's hard to say.But with the breech plug design above it will work with T7,White hots etc.but I have to say that I'd be surprised if it lights off BH209 without a delay. That's why I would enlarge the flash holes in the cases and use small rifle or small rifle mags. Good luck!

SW, Give Denny a call tonight. He's closed now but if you leave him a contact number I'm sure he'll call you back especially if he knows it's concerning the .32 ACP conversion. I've just finished my 4th conversion and am very pleased with all of them. I've been wringing out my .54 that's pictured above and after 40 or so shots I disassembled my bolt and there is absolutely no crud on the firing pin spring or rod whatsoever. Quite unlike before. Again, this is NOT a smokeless conversion. I think this solves the one problem that plagued the 700ML. Good Hunting!

nmaineron, Not really, I just installed an old style short action ADL walnut stock that I picked up on Ebay for $23. I traced over the "smashed checkering" with a Gunline 18 lines per in. checkering tool for a little better grip. That's what's great about a 700 ML. There's a lot of inexpensive HOT ROD parts for them. When looking for a wood stock for my Savage, I got nailed pretty hard for $103. It was a nice cut checkered stock but it was beech not walnut. Both rifle's balance were enhanced considerably. I'll have to recruit my son to post a picture when he's around. Thanks!

I believe in a previous post I wrote that it was $180 plus S&H. If your interested Give Denny a call at 330-534-3707. It's works great,but then I'm not impartial.
