Load data for .32 H&R Mag using 98 - 100 gr bevel based full wadcutters?

[4given]

I have had no luck searching for Load data for .32 H&R Mag using 98 - 100 gr bevel based full wadcutters. I would like to push them to around 750 fps in a 2” bbl.

Any help would be appreciated.

I load mine with 2.5 grains of bullseye.

[Larry Gibson]

Try 1.9 to 2.5 gr Bullseye.

[4given]

Try 1.9 to 2.5 gr Bullseye.

I don’t have any bullseye right now but but I have Tight Group, AA #2, Hp-38, CFE
Pistol and a little Unique.

[Nobade]

Tight Group will do about the same thing as Bullseye. Somewhere between 1.5 and 2.0 grains.

[Larry Gibson]

What Nobade said.....

[Thumbcocker]

I use 2.5 of Promo

[Gar10]

I haven’t found any load data for 32 H&R using Accurate Solo 1000. Has anyone here ever used this powder for 32 H&R?

[RugerFan]

I'm using 2.5 gns of Unique.

Quickload may not be super accurate, but it should get you close. QL shows 23496 psi as max, these are all well below that.

QL barrel length is muzzle to breech, so I use 3.5" for a 2" revolver.

Bullet is a swag, I guessed at 0.5" long. COAL is also a swag.

QL does not consider cylinder gap, so I assumed 50 fps

Cartridge          : .32 H&R Magnum
Bullet             : 100 gr x 0.5" long WC
Cartridge O.A.L. L6: 1.150 inch = 29.21 mm
Barrel Length      : 3.5 inch = 88.9 mm

C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.

Thank you, P Flados for posting this information. Very much appreciated.

I just ordered a copy of the Lyman Pistol & Revolver Handbook 3rd Edition Reloading Manual. I am told it has the answers we seek. I’ll let you all know when it comes in.

The manual came in. It only has data for a 90 gr swaged HBWC and a bunch of jacketed bullets. Lists starting loads with a number of different powders so that is helpful. Not exactly what I was hoping for but it helps.

[racepres]

My Lyman 2nd edition, Pistol & Revolver book, shows a 95gr full wadcutter load of 3.0 gr of Unique netting 751fps, in 32 H&R Mag
slightly faster with 2.5 of 231. Betting the 3rd edition Cast manual has the Same...Edit; The 47th has same loadings!
My experience with BE-86 thusfar has been that a Grain for Grain comparison with Unique results in almost identical performance...
Note of Caution...I have Not got to the H&R Mag loadings yet...May be awhile, because I like AA#5 so Darn much in 32H&R as well as 32S&WL.
I have fooled with BE-86 in 32S&W (no L)...so far No Surprises!

I would expect a cast wc to hold a lot more lube and be of a significantly harder alloy than hbwc's coming with a factory dipped lube. They should hold up to quite a bit more pressure and velocity.

I concur. I’ll be using MBC coated 98gr cast wadcutters. This data will give me a great place to start.

Here is data from Reload Ammo (formerly MD Smith Reloading Pages):

98 Grain HBWC lead (.314″)

Bullseye 2.3 gr. 810 (max)
Unique 4.0 gr. 998 (max)

[rintinglen]

That Unique load is pretty stout.

That is the max load for the 32-98 SWC in the RCBS Cast Manual, which is not renowned for its mild loading. I would start at 3.0 were I you. The Lyman 4th edition has some data for the RCBS 32-98 WC, but it is very much underloaded. It would appear that they used data for a HBWC and simply stuck an RCBS flat based boolit in the case and called it good.

[racepres]

But..When you shoot the above H&R Mag load of Unique...you will find it Mild Indeed..
I personally have Not cared for the Cast full wadcutters...certainly Not in H&R Mag.. But, delight in SWC's
Near as I can tell...those Hollow base WC's are for S&W Long Target loads... and should be loaded accordingly...Just like HB 38 SPL.

[P Flados]

That Unique load is pretty stout.

The old 2004 Alliant booklet had 4.0 gr of Unique under a 98 LRN with COAL 1.32 for the 32 H&R Mag with pressure shown as 19000 psi.

Note that the COAL above is rather long but the lack of any info that would allow determination of bullet length makes seating depth a mystery.

Quickload says the max press for the 32 H&R mag is 23496 psi. With 4.0 Unique and a Lee 93 adjusted to 98 gr, it gives 19000 psi as the predicted pressure with a seating depth of 0.339".
