7.65mm Argentine Reloading

[Marksman]

Folks,

I've recently acquired a very nice Argentine M1891 Mauser rifle (cal. 7.65 x 53mm) and need to handload to put it back into use on the range.

I've a good supply of 174gr and 190gr bullets (0.311" -0.312" diameter) that I use for reloading 0.303" British and a range of Vihtavuori powders.

Any suggestions?

Thanks.

Mark.

Sir,

I do not nor have I ever used VV powders in my mod 91 mauser. I usually make my own cases from any good reformable cases 30-06, .270 Win, .280 Rem., ect. using a RCBS file trim die, hack saw and file. I also aneal the heck and shoulder before re-forming. Yes they are just a tiny bit small but in my experience of over 40 years they work just fine. I have shot a few of the heavy bullets that you mention but my hunting loads are always either a 150 grain soft point or 123-125 grain fmj or soft point. May I suggest that you work up your load starting low and going where you decide to go, a 91 is a very well made and fine rifle but not as strong a action as a 98. For powder I use IMR 4320 or IMR 4895 but I would imagine that there are lots more that can be used. My primers are almost always CCI but most any Large Rifle will do except for magnum. If I were to use magnum primers it would only be for use in igniting ball powder or extremley cold weather, I don't think England gets that cold. HTH

By the way my Dad spent some time in England before going over to Normandy on his whirl wind tour of Europe.

Any safe load that works well in the .303 British case will do about the same in the 7.65x53 - at slightly lower pressure since the 7.65 case has a grain or two more capacity. Velocity in the long-barreled 1891 Mauser will be close to the .303 with a 25" barrel.

This may give you a ball park idea of the speed of military ammo in a military barrel:


Argentine M1909 29" Barrel
17-Apr-92 T ≈ 80 ° F
174 gr FN 1978 Ball ammo

Ave Vel =2503
Std Dev =10
ES = 26
Low = 2489
High = 2515
N = 5


Now let me add what I think is a word of caution. Your rifle, as beautiful and wonderfully machined as it is, was made in 1891. The metallurgy of that era were positively primitive. The materials of that era are highly variable in terms of things like slag and inclusions, reflecting the primitive process controls of the times.

So don’t hot load it.

I carry a 7.65 Arg around my farm. It has a 18" bbl, Timney trigger, Williams rear peep, and a dayglow front ramp, and fits between the seats of my truck. I drawfiled the step out of the bbl and rust blued the whole thing. It is in a lightened sporter stock, glassbedded. From a rest, I can put 5-shots in 1" at 100 yards with 150 gr 311 Speers using the peep. I can't remember the powder wgt, but I use IMR 4895 with Winchester primers in Norma cases. I installed a push button for the clip release, and carry an extra loaded clip. I use it for snakes.

I can stand erect and holding it with my hand on the trigger and pointed straight down, the barrel doesn't come close to the ground. The barrel and receiver were both new, with the receiver never having been used (or ground). Muzzle blast is a bit on the heavy side, and recoil is a hoot due to very light weight (<6 lbs loaded). It is a fun rifle to shoot, and anyone who has ever picked it up likes it.

I also converted a Arg Mauser to 300 Savage, and it is very accurate. I converted another to 22 Kilborn-Hornet (shortened it). I like the Arg Mausers, and own half a dozen of them. I will check out the powder weight tomorrow. I have fired many hundreds of rounds through my Arg Mausers, with not a single problem.

You will like the 7.65mm Arg.

A good load for deer is: Hornady 150gr SP using 42gr of IMR 3031 with CCI 200 primers (good luck finding primers!). 42gr of IMR 4895 will give you +/- 2500 ft/sec. Use the above at your own risk. Don't forget, you have to use "British" bullets (0.311") not 30 cal. It's a good idea to have several reloading manuals for comparison and always start on the "low" side.

"...You have to join..." Right. Silly me and it gets worse(bordering on really stupid on my part). I should have looked. I have data in my 45th Edition Lyman manual. 150, 180 and 215(nobody makes a .311" 215 grain bullet any more though) jacketed and 155, 205 and 214 grain cast. 180 grain data will do for your 174's. E-mail me and I'll send it. toheir@hotmail.com
Go here too. The 7.65 x 53 Argentine and 7.65 x 53 Mauser are the same thing.
