View Full Version : .32 S&W Long Wadcutter Loads for H&R 733

I have an H&R Model 733 double action revolver chambered for .32 S&W Long. It was manufactured in the early 1970s. It is a solid frame, swing-out cylinder design.

I have 85 grain DEWCs from Matt's Bullets (https://www.mattsbullets.com/index.php?main_page=product_info&cPath=69&products_id=302&zenid=q00dedssrh08d8a2d6pilluuj3) cast in what appears to be a discontinued Lee tumble lube mold.

I would like to load "full power" wadcutters. Not looking to hotrod the gun but I'm looking for something that will approximate the MV of the factory 98 grain LRN with a more effective profile. Powders I currently have in stock include Alliant Bulleseye, Unique, and Red Dot, and Hodgdon Universal and HP-38.

I am aware that wadcutters take up more space in the case and that can cause pressures to spike if seated too deeply. I am not averse to seating them long, i.e., to the same length as the factory LRN bullets.

I checked in the Lee Modern Reloading Manual 2nd Ed. and on Loaddata.com but I'm not seeing any useful data for this bullet and the powders I have on hand.

I was hoping that someone else has used this bullet and has some suggestions.

I would seat out to 1.20" OAL and load 2.0-2.2 grains of Bullseye or Red Dot, or 2.5 grains of HP38 or 3 grains of Unique.

I was hoping you'd chime in. Thank you! I will give this a try.

I would agree, 3 grains of Unique. Can't really hotrod loads in this gun but this should work good for a 5 foot (belly shot) load.

I do not know the size of your cylinder throats or bullets, but make sure when seated long that the wadcutters chamber freely before making a large batch. If they chamber too “freely” make sure you have a decent match between cylinder throat size and bullet size.

When seated to standard wadcutter depths 2 grains Bullseye gets around 700-720 fps with a 98 grain RCBS wadcutter and Red Dot goes slightly faster. Given the 32 has surprisingly high velocity variation with more shallowly seated bullets, to my surprise anyway, there is a practical limit to seating a lightweight bullet out past a certain point.

A sort of point of diminishing returns, I would say.

98g RCBS and Red dot at 2.5g has been good in my guns.

Good point re seating them out and verifying they chamber. Will do.

What bullet style and cartridge OAL?

I have a H&R 732 (blued, 2.5") had a 733 that I passed on to my shooting buddy.

I'd have to agree with outpost75.

In mine I love 2 grains of Red Dot.
Bullet wise I love the Lee .314 90 gr truncated cone. It shoots exactly where I point it both in the H&R and in my Ruger New Model Single Six in .32H&R mag.
(Have only shot .32sw longs in mine thus far)

Shoots a lot like .22lr, low recoil, low flash/muzzle blast, low muzzle flip. Goes right where I point it.

Assuming you can get 750 ft/s, the graphs below show how effective that 85 grain wadcutter might be:

259423

The 15 inches of penetration is better than many .38 Special +P JHPs and 15 grams of wound mass is about the same as 9mm FMJ or any non-expanding .38 except a wadcutter. Nothing to sneeze at.

It’s a 32 Long. It’s a RCBS 98 WC Mold. It’s a wad cutter bullet style. Seated to crimp groove as designed.

(I have done same in 32 H&R as well as 327, but the OP of this thread asked for 32 long wadcutter load information)

That's even better...

My advise also.

Interesting thread. I have for the last couple of years restricted my 32S&W Long loading to 98-100 grain swc's; other than one fling with 115 grain swc's, that I shared with Larry Gibson. But in looking around in my storage bin I came across a carton of .312" 90 grain hollow base swaged wad cutters. Originally had 500 in it, but appears to be about 300 left. Pleasant surprise finding that. So I am thinking about loading them with about 1.9 grains of Bullseye; since my pet load with the 98-100 grain swc's is 2.1 grains of bullseye. Hopefully it will be a nice accurate load in my 32's.
