"115 grain .32 H & R magnum loads?"

[exile]

I recently acquired a small quantity of .32 caliber 115 grain RNFP bullets. I plan to shoot them out of my Ruger SP-101 in .327 Federal IN .32 H & R MAGNUM cases since .327 cases are not available. I have only been able to find one load in my manuals that may work, although it is for the .32 S & W long case, (3.5 grains of Unique). Any ideas? Since these will be shot out of a .327 Federal, I assume cartridge length will not be much of a factor. (These will be loaded in new Starline cases).

It seems to me that the .32 H & R magnum is the cartridge with the least useful published data on the planet. I could find no published load data for heavy bullets in this cartridge, and nothing that would really qualify it as a "magnum" cartridge. I am still waiting for Starline to make .327 Federal cases. Loads do not neccesarily need to be fast loads to be useful to me. Thanks.

I have used 3.5-4.0 grains of Unique with 115-120 grain 32-20 boolits in the 32 Magnum with fair to decent accuracy. Not a "magnum" loading, but has more zing than the 32 S&W Long.

In my experience, 90-100 grain bullets give better accuracy in the 32 Magnum than do 110-120 grainers. Your revo being a 327 Federal gives at least one new variable that might change that all around.

The most detailed/extensive listing of 32 Magnum loading data I've run across is contained in the well-aged RCBS Cast Bullet Manual. My copy is lost somewhere, expletives deleted. I think it was published in 1986, give or take a year or so.

I've had real good luck with 4.0 grains of Unique with 115 gr boolits in my 32 mag, lately I've been using some old Winchester 540MS I picked up which I think is close to Hs-6 with assume results. Good luck with your 32 I really like my Ruger 32 Single Six Bisley's.

Here's twice around the cylinder at 25 yards with a 4" M16 with 311316 cast of WW over 4 gr Unique in Starline .32 H&R cases. As you can see the 973 fps velocity was very consistent as was the accuracy (1.6" group). That was about as good as i could do 15 years ago with the short sight radius.

Thanks guys. I will probably start with 3.5 grains of Unique and end up with 4. Should be fun. I will let you know how it goes.

Try finding .32HRM brass. I have a gun coming and can't find anything available but Lapua. I know, it's great brass, but geez it's pricey. Even .32 long is sold out.

Hodgdon's data here . http://data.hodgdon.com/cartridge_load.asp Work up from just below their 100 gr jacketed data. Try their 800x .
Also try starting at 5 gr AA#7

Check out the cast bullet assoc. forum.A number of the guys are fans of the .32.Loads for handguns and rifles can be found using most any weight bullet. Love the .32

The 32 Mag data is underloaded dure to the fact that the pressure levels are for the weaker H&R pistols. (21,00 psi) A ruger 101 and the Ruger Single Six can handle up to 40,000. CB Harris has done some load development in the 32 Mag. I read an article where 5 g of Universal Clays with a 85 to 100 g bullets are used. I got 1396 fps with a 90 grain bullet. Easy extraction with my SP 101. This is a Max load.My pistol had just started to show pressure signs. (Your results may vary) The load produces 334 ft pound of energy.The standard 45 acp is I beleive around 370? Just my 2 cents

try 7.0 grains of 2400 i used 8 grains with a 100 gr bullet in .32mag

I use Lil Gun with good results.

Wow, you guys are a little late with responses...just sayin'

Starline has 327 brass, I just received 500.

Yes it does, this thread is recently resurrected from 2009.

I am working on this wonderful cartridge myself, using the Ranch Dog 115 grain LFP. Right now I'm using 3.5 grains Titegroup for 850 fps out of my Charter Arms Undercoverette with 2" barrel. Next up I'm going to try Accurate #5.

4.0 grains of unique behind a 115 grain boolit changed my brother's prejudice against cast boolits. Before using that load, he thought the only thing boolits had in their favor was that they were cheap.

It has been the most accurate load so far out of his Ruger.

5.5gr. AA#5 and the #3118 will shoot groups around an inch at 50 yds. from my scope sighted S&W M16 and my 10" TC Contender. I use gobs of them in pistol silhouette matches. Just tried the Ranch Dog 32-20 boolit and it does the same thing. Both are plain base and cast from air cooled wheelweights, BTW.

[FergusonTO35]

Ranch Dog may be able to provide you with data for his 115 grain .32-20 boolit in the .32 H&R. Also, Laser Cast Bullets does have some data for their 115 grain slug in the .32 H&R. they will send it to you for the asking.

In .32 H&R Magnum revolvers I shoot 10.0 grs of H110 behind a 120 gr RF cast bullet. This chronographs at 1100 fps with decent accuracy and punch.

FWIW

A couple of days ago I tried 4.7 grains of Accurate #5 under the 115 grain Ranch Dog boolit in my Charter Undercoverette .32 magnum. Very accurate load, as long as I did my part it would bullseye it at 10 yards. I ran it through my chronograph, 805 fps average with an extreme spread of only 12 fps! Accurate #5 has always been superb in my .38 Specials, looks like it will do well in the .32 also.
