Graf's: Prvi Partizan Brass 7.65x53 Argentine Mauser Unprimed Bag of 100 $58.99 (in stock)

Don't know what your time is worth, but if it is worth much of anything you can't make the brass from .270 or .30-06 brass for $0.69 (shipping included) each. And, of course, the NNY brass has the proper headstamp.

I made a few hundred from LC '06 brass a decade ago. Most is still working for me.

Why not make it? Ya only likely need do it once

[Phat Man Mike]

Yeah , she scored some old 30-06 blanks. Thought it could be turned into 7.65 with a little bit of work. I've seen the die somewhere.

[Der Gebirgsjager]

I'd approach the use of .30-06 blank brass cautiously. It was said to be of 2nd quality, deemed insufficiently strong for regular loads but O.K. for blanks.

I looked and looked for one this summer. Gave up and tried without...no issues. Just use your sizing die. Lube and size without the expander, then rough trim them, put them back thru with the expander, then trim to size. Don’t use the blank brass, it may not be up to pressure in quality. Resize true ‘06, 270, etc.

[Der Gebirgsjager]

Nice little chop saw, Stewbaby. I'm sure that would work.

My longtime form die for 7.65 Arg. is the FL sizing die.

I've been around long enough to have an old "file trim" die for it but cutting off the excess length normally isn't very demanding.

[Phat Man Mike]

Ok, so just chuck the blank brass and use 270 brass. I can't use 30-06 she has 2 of those rifles also. She keeps me busy sometimes trying to feed them .

[cwlongshot]

Yes, Just use a GOOD LUBE like Imperial Size wax and your 7.65 Arg sizing die. I also find annealing helps allot with split necks.

Good luck

Mike-- Yes, chuck the blank brass. There have been several threads on the .30-06 to 7.65mm conversion in the past, a couple of them very extensive. You can probably turn them up with a couple of "searches". Some good reading. I've got several 1891 Argentine rifles and converted several hundred rounds, and they work very well. I did use a trim die, but I think Stewbaby is right that one really isn't needed as once the brass is reformed all that remains is cutting the neck back to the correct length. I think some careful measuring, filing, and de-burring would do the job. Some claimed, in past threads, that the thickness of the neck of the reformed cases have to be reamed, but I never found it to be a problem.

I've got a couple NOS 7.65 file trimmers.

Thanks Gmsharps. She's going to be happy now.

Not trying to challenge you but I’ve formed hundreds of 765, 7.7, 7 and 8 X57 from US and Canadian 06 blanks. Never had one go bad. I started way back in the 70’s when the only source of brass was buying factory boxer primed ammo and saving the brass. Norma brand was the exception as they made military brass available but the prices were near ridiculous.

I’ve heard and read from various sources over the years about being cautious loading blank brass but I never had problems once the brass left my loading bench. I did booger up plenty of brass while reforming. The most common problem was getting a wrinkle in the neck or shoulder area. As an advisory the 06 blank primers are corrosive. I de-primed the live corrosive primers very cautiously as the primers are crimped in. I never had a primer ignite on my loading bench but pushed them out very slowly. I occasionally had a stubborn primer and simply discarded the brass.

I had better luck annealing the brass’ shoulder area after the initial fire forming. Seemed I had a lot less split necks that way.

Kill live primers with a shot of penetrating oil (or regular) and don't worry about depriming cases. Water works but the primers need to be wet (not allowed to dry out) to be absolutely sure they won't ignite.

Gary; do you have another 7.65 file trimmer?/if so, how much? Interested, and if I buy, it can be shipped with the 280 AI dies I bought from you. Let me know, thank you. Baumann

Hi azrednek-- No problem, I don't feel challenged. I'm here to learn, like most of us are. As you noted, the information about lesser quality brass being used for US Military .30-06 blanks has been stated and quoted for years. I think that there would have to be a basis for it, especially the WW II vintage production, as if you had a large batch of brass that didn't pass inspection for use in loaded ammo you probably wouldn't want to let it go to waste, especially if there was a need for training blanks. I've had a belt of about 500 of the blanks with the red paint in the top of the case for many years, but never did anything with it other than use it as décor in my shop. But your experience in this area exceeds mine, and I'm glad that you've successfully put yours to use. Now no one said anything about Canadian blank brass that I've ever heard of, so I can't say anything about that at all, but have heard that most foreign countries use the same high quality brass for their blanks as for their loaded ammo. Some of the foreign blanks have a severely crimped mouth to assist in feeding in automatic weapons, and I doubt if they'd prove of much use. Anyway, my conclusion would have to be that, based on your experience, obviously the US Military blank brass varies in quality. How one would make that determination without actually trying some is the question.

About the .30-06 to 7.65mm conversion specifically, I always started the project by annealing. I'd stand the cases upright in a baking pan with water about half-way up the case, heat them with a propane torch until an orange red, and then immediately tip them over into the water using a short piece of welding rod. You can only heat up one or two at a time, because they lose heat rapidly. After they dried out I'd simply run them into the 7.65mm sizing die, trim them in the trim die, and de-burr them. I can't recall ever losing any cases at all. I'm thinking that you should probably do the annealing step before the sizing, or you said fireforming. Norma brass? Always too expensive for me.

Check the neck thickness of your converted brass, it may or may not need thinning. When I did this ~thirty years ago I just used the Lyman full length sizing die, and cut the ridiculously long neck with a small tubing cutter before using a Lee case trimmer.

Now I would use the Harbor Fright chop saw like Stewbaby illustrated.

I've bought a Hornady neck trimming tool to shave down the ones that are a bit thick . Thanks everyone for the great information . After making her brass she wants chicken coops.

I made mine from .308 win.
