Anybody have the Hodgdon, Hornady, and AA is it? load data?
Shooting both a BlackHawk and 18" contender carbine.
Thanks

Hodgdon and AA data is available online! Hornady's data for H110 is 16.6gr start, max 18.5gr, COL 1.890", Rem brass, Rem 7½ primer.

My favorite powder for this caliber is AA1680.
I use it for hunting so I prefer the heaver bullets. 180 and up. the one exception is the Speer 170GDSP bullet.

My load is safe in my guns, a Contender and a H&R 357Maxi is 26grs.

I have chronographed this load with Hornadys 180 SSP and Speer 180FP bullets both top out at just under 2100fps with cloverleaf accuracy at 100yrds. The SSP is too light for this velocity on whitetails, the Speer holds up well.



Never tried the 200RN as the 180FP preforms so well. The GDSP from Speer is the new kid on the block for me. i have used the 44 version in 270GDSP with EXCELLENT results, so I have high hopes for this little 35cal brother.

Thanks for the reply!
Tim- which bullet is the Hornady data for? Neither Hogdon or AA list either bullet online.
CW-I mentioned the 1680 due to your reply to a previous post. I can't get the 170GD to group at 100 yds with either H-110 or IMR 4227. So I'm trying this powder next. The 200RN has shot under an 1" at that range in the contender but opens up in the Blackhawk. The 180 HP/XTP shoots 2" in the long gun and about 5" in the revolver.
Great list

The Hornady data is specific for the 180gr HP-XTP #35771, 180gr SSP #3505 and 180gr CL-SIL #3577.

YES , good catch Quick!!
 Defineately read your manuals!!! These bullets are canalured to seat at different depth's in the case so you will find a "range" of max loads with the same powder!!!

 As a matter of fact the 170's I just loaded have a max load of 23.5grs listed!! I have shot the Sierra's at the full 26 Gr's IN MY GUNS to no ill effect, the primers are JUST BEGINNING to flatten. They are not as flat as my reg 357 mag loads with 18.0grs H110 and a 140 HP. NOT a max load!!!

I use the 180XTP and 180SSP, I found that IMR4227 at 21gr gives me what i am looking for. I have used Hurcules 2400 that was given to me I went to my T/C manual and used the accurate load data and it was fine. I shoot a 14inch contender with a 4X scope MOA is no problem. I did not like the SSP on deer Small entry and exit, the 180 XTP Hollow points in my shots gave me better results. Good luck Read everthing you can find and be safe.

I finally got some data to go on

HR 22" 357 max,  25gr RE 7,  Horn 180 XTP  --   1850 fps 

that is barely more ME than the factory 357 mags get me.  So its back to the books on this project, which is a good thing.  I need a science project for the winter months.  I was hoping the RE 7 would do well because I am happy with it in my 45/70 and like to minimize the cans of powder I have to keep track of.

Im getting a 44mag soon and may stretch it to a 445sm so I will look for a powder that will be a good option for both the 357max and the 44 mag/sm.

one note however, the RE7 was very consistent for velocities in the maximum.

bajabill,
If you are looking for accuracy and punch try the Hornady 180 sp rifle bullet and AA1680. From 25 to 27.5 grains. Seat the bullet in the cannelure - this cartridge exceeds the maximum length and cannot be used in revolvers but in single shot pistols and rifles it is accurate and will give you very close to 2000 fps.
The Speer manual also lists a load for their 180 rifle bullet in the 357 Maximum. 25 to 27 (compressed) of AA1680 at 1884 fps and 21 to 23 grains of H110 at 1880. These loads are also loaded too long for revolvers but work well in singles shots and some rifles.

As always start low and work your loads up while watching for signs of excessive pressure. Stop when you find an accurate load or when either reaching maximum listed load or the any sign of excessive pressure. (with pressure signs back the load down to where it was before you noticed any signs of excessive pressure and use that as your maximum load in your gun.

For the revolver users the best load I have used is the Speer 158 JHP with 22 to 24 grains of H110. you get over 2000 fps with this load and the bullet performs very well.

Thanks for the great info. I knew this was the right site!
Any others with Max tips please weigh in.

I am much happier with H110 in my Max

21g and 1975fps in a 22" barrel.  Even my starting load of 19 beat RL7 at max load.  The H110 grouped well also.  My only complaint with it is working with it, the small spheres are not as userfriendly as the extruded powders I typically use.
