7.65 Argentine load

[smkummer]

I am going to load for a buddy's 29" mauser. The only higher powered load I can find with cast is a 15 grain Unique load behind a 155 grain Lyman bullet going out at 1800 FPS. That may be just right and I am going to use the Lee 155 TL bullet intended for the 7.62X39. The only sizers I have are the .311 and .314. I'll have to run them through the .314 to seat the hornandy gas checks. Anyone have a 2400 load if I want to go faster? Has anyone shot this bullet out of the 7.65 argentine? thanks in advance.

Did you slug the barrel? that would be my first step.

I've just most recently was testing my 867 surplus powder in the 7.65 but I was using the Lyman 314299 which is most certainly heavier then the bullet you want. I was pretty well over 2000 fps with the test load and the accuracy was very acceptable, plenty good enough for deer hunting and groundhogs. The recoil was getting a little snappy at that velocity.

Why do you need a load with that high of velocity?

BTW my bullets are sized at .3135

[smkummer]

Well, maybe I don't need more than 1800 FPS. I was wanting to make a load close to 30-30 performance, so with a spire bullet, it would be fairly flat shooting out to 200 yards. Again, the 1800 FPS load might just be right as its more economical to use Unique than 2400. I will slug the barrel when the gun gets here but I am going to pre-load the ammo with a .314 sized gas check bullet. I already check some fired empties, and they chambered so I am going to neck size only.

You'll find a flat nose or even a round nose will perform better on the deer then a spire point. Also spire points can be rather hard to get to shoot accurate.

I've had good accuracy with that bullet in both my M91 and M1909 7.65 Argies using 4759 with a 3/4 gr dacron filler. Suggest you start at 16 gr and work up in 1/2 gr increments. Best accuracy load will be in the 17 - 20 gr range in the longer barrels. My mould drops the bullets at .313 - 314 and I size, seat GC and Lube in a .314. That works fine in my 7.65s.

I would think that 2400 and 4227 would also be good powders with a 150 - 160 gr cast GC'd bullet in the 7.65 Argie but have not tried them .

smkummer,

I've found out testing the 867 in the Swede and the 6.5x54MS that it gets the velocity with less pressure then many other powders. Sort of like Hornady's new blended powder in their updated Enhances HV loads.

[smkummer]

I just ran out of 4759, so I might have to get some. My buddy's 1891 is in excellent condition (colorful pattern swirl wood and excellent blueing) and looks fun to shoot. If the unique load works, we just may stay with it. For what it's worth, I am using a 32 acp sizer die to size the neck, a 30 carbine expander die to expand the mouth and a 308 win. seater die to seat the bullet. I too used the Lee .314 sizer to basically seat the gas check although I did feel a little sizing taking place. I will be able to seat the bullet out so as the gas check is still against the case neck with the OAL still within limits.

smkummer,

I've tried my 32acp die to size down the necks of more then the 7.65 and found them not good. They didn't size down enough. I can tell you that a 308 Win sizer die will size them down, but you have to adjust the die up so it just sizes the neck without bumping the shoulder. If you adjust you decapper/expander right you can do your cases in one shot.

I make up spacers on my lathe for adjusting dies to other caliber neck sizing only.

[smkummer]

For me, the 32 ACP Lee full length sizer sized the 7.65 argentine neck well enough to hold the .314 sized Lee bullets quite firmly. In fact, I had to run the 30 carbine expander in a good amount to flare the mouth to accept the gas check bullet. The big test will be the range sometime this week. Thanks to all and can't wait to burn some powder out of this fine old sweet gun. I believe he paid around $200 for this mauser and if we get it to shoot cast bullets well, whats not to like about that!

Loading for power my M1891 Argentine shoots the new Lyman 314299 ( heat treated, sized 0.314 ) over 38 grains IMR 4350 very well indeed right on out to 800 yards.

Loading for accuracy the rifle shoots the old, oversize Lyman/Ideal 311284 (sized @ 0.314) over 21.5 grains IMR 4198 into MOA very reliably.

Good afternoon,

What is the inside dimension of the neck after you size it?

Depending on how hard your bullets are the 30 carbine expander may leave the neck too small then the bullet gets sized down as it is seated. The Lyman M die opens up the entire neck so this does not happen, supposedly.

[Bret4207]

You really ought to blow the $20.00 on a set of proper dies from Lee. The Argie deserves it. And if you want a good boolit then get in on one of the group buys for a "Fat 30". Using a very simple 13.0 Red Dot load behind the first edition Fat 30 220 gr boolit my Argie makes nice round groups that only limited by my eyesight.

[smkummer]

We didn't shoot it on paper yet, but my friend likes the low powered load of 15 grains Unique and this bullet. We were plinking a used up helium ballon filling tank at 50 yards and the battle sight was right on with the lead bullet. Lots of fun and low recoil to boot. Next time we will be going to 100 yards. Specs:
Bullet sized to .314 and 30 cal hornady gas check
Neck sized with 32 acp dies.
Neck flared with 30 carbine expander
Bullet seated with 308 seating die
Norma used brass (some of this was tight as I never full length sized but after firing, it came out easy and now it chambers perfectly with no resistance).

18-19 grains of 2400 under that bullet is a favorite load for my '09 Argie carbine. Using the military sights, I can consistenly hold 10-round strings inside the 9-ring of an SR-21 target at 100M.
