Is anyone loading and casting for this ine?
I have had them for decades most as platforms for custom rifles in other calibers. A couple got shot a bit as 7.65’s.
Two years back I picked up a 1889 Belgium Mauser largely because it was made in my home state of Connecticut! Its in average condition with a nice bore and all matching only issue is safety it works but its sxrew is “screwy” I made up 20-30 pcs of brass and loded up some light cast loads but never have shot it. Last fall a hauled it out and went thru it completely and even made up and posted a video to my uTube channel. A Couple weeks back, I pulled more ’06 brass and made up more brass. Well I was stupid and lost many because I didnt set the dies proper. So last week I made up 100 properly and only lost a single case. Even that one was 100% me as I just rough chopped it short.
I also have a 1909 that was destined to be a 257 Bob but I decided to leave it 7.65 so I stocked it and mounted a scope. Im waiting on a Timney trigger and It can go to Bluing. I might just do a rattle can on thsi one. Never have before. Not entire gun anyhow.
Looking thru my dies I find two they should work well and four more that are fat enough to work with PC. My 314299 & 312-155 2R molds. Of the other four, a 311335 & 311284 HP are best. Even that LEE is lighter then I want to shoot. (Unless building just plinkers)
Yesterday I cast up a couple hundred 311284HP bullets. They dropped 315 with Soft WW alloy. (Should be 12bhn) For me everything revolves around my ability to hunt with it. So with my newly formed cases and these bullets Ill work up Loads looking for 1800+ fps then test expansion and adjust alloy. I know at that vel ill need harder alloy but its what I had in the pot.
Has anyone forded this river? Love to hear your experience. I am kinda amazed at all the 7.65 videos on eBay! I paost up a four part series on how I made 30/06 into 7.65 Mauser brass to add to them. 😮

Does this attached cast bullet intel for the 7.65 Argentine – Belgium Mauser help at all?
I have QuickLoad and have loaded a goodly number of NOE cast bullet designs.
If you are interested PM me with your email address and powder – bullet designations etc… & I will send you more intel.I no longer post the entire QuickLoad pages on the forum or the internet as there are critical SD & COAL dimensions that need to come into play must be followed for the data to be accurate… Also the details tend to be lost when one runs the scan at a low scan rate to be accepted as an NOE forum attachment.
Besides there are technical liability issues that tend to go along with videos and such data postings which I am sure that you must be aware of by now…
Have you measured the internal H2O water weight in grains for your home brew 7,65 brass manufactured from 06 brass in comparison to the actual 7.65 Mauser capacity… That will be an important detail to feed into the final load calculations…
Otherwise the data may be off a bit pressure wise especially if you tend to push the limit in velocity and pressure… with your reloads.
Once the QuickLoad data is determined it can then be fed into QuickTarget to determine the ballistic predictions for target – Hunting purposes… It tends to save a lot of time at the range along with powder & primers which tend to be scarce at the moment… besides it is fun to verify the ballistic predictions at the bench.
I also subscribe to LoadData which is where the second attachment is from…
If you are looking for a hunting load then this might be an option for you to try…Take Care, & Stay Safe…
I’de go with the 5744 powder.
I’ve always had better luck with that particular powder… over 4759…That way you can get to your 1800 fps +, & also have a 100% clean burn rate… and still be circa 30,000 PSI with circa 1800 fps velocity…
Personally I prefer the 311299 (~202) GR over the 311284 (~210 Gr), but having both it will be interesting to see how the 284 compares with the 299.
The 311299 was originally intended for the 303 British cartridge… So it tends at least for me… to be a bit more accurate with the European barrel makers rifling…
It will be interesting to see what you find that the 284 does in comparison…
Take Care, & Stay Safe…
