The .357/.44 Bain &
Davis (B&D)
Why do a page on the 357/44 Bain & Davis? In it's time, it was a
leading kick-butt revolver round, offering 357 Maximum performance
in the stock revolver cylinders (1.290 case length). So... why not?
Some of the articles were written by people who were there. Way
before QuickLoad, cheap digital chronographs, current powders,
and... unfortunately, lawyers. Many lawyers.

Why the 357/44 Bain & Davis?
My interest with the .357/.44 Bain & Davis round
came in the form of a 22" Encore barrel. This round approximates
the performance of the much vaunted 357 Remington Maximum (which
is the .357 Super Mag, developed by Elgin Gates) in revolvers, not
just in a T/C Contender. S&W Model 28 and
Ruger Blackhawks have been chambered for this round, as have
Winchester 1892 lever actions.
Who Came Up With the Conversions?
The fine folks at the Bain and
Davis Gunshop in the People's Paradise of California (5 Dec
2017, not getting it to load...). Dies and reamers are
available. (I have Hornady New Dimension dies). "Developed
in about 1964 by gunsmith Keith Davis, the .357/44 Bain &
Davis was intended to be used in modified .44 Magnum revolvers in
order to improve the velocity of 158 grain .357 caliber bullets
compared to .357 Magnum performance. It also gave long barrel
performance in a standard length barrel." (Accurate Powder
cartridge description)
Comparable Cartridges

.357/.44 Bain & Davis has a case capacity 33 grains of
water. The case shape with the significant taper is the shape that
current dies use. The first shape (circa early 1960s), with the
normal bottleneck shoulder (25 degrees), proved to be more prone
to set-back. The current version (circa mid 1960s)
uses a significant taper (10 degrees). Writers mention that
setback becomes noticeable with extremely heavy loads using the
current design.
.357/.44 Bobcat, which is a similar shaped round.
However, it uses a poly ring around the neck in conjunction with a
357 Mag cylinder that has been bored out at the rear to accept a
.44 Mag body. The front of the cylinder has a .357 mouth.

.357 Auto Mag Pistol (AMP), another contemporary round (case
capacity 35 grains of water). The 357 AMP cartridge is based on
cut down and reamed out rifle brass (308 headsize). It is much
easier to form 357 AMP using 44 AMP cases. Starline does make 44
AMP brass, but only when sufficient orders are on-hand. Quality Cartridge makes 357
AMP, but pretty much the same deal. Midway lists the
AMP cases as back-ordered, while Grafs has 44
AMP, both brass and nickle plate (as of 20 Jan 2013).
Cartuchos Deportivos Mexico (CDM) made a single run of 44 AMP.
Norma supposedly also made 44 AMP, but I don't know how much.
Corbon has made loaded ammunition for the 44 AMP, but that is an
expensive way to get brass.
.357 Remington Maximum is a straight walled case. However, it's
case capacity is 33.6 grains of water.
Forming the 357/44 Bain & Davis
Buy new 44 Mag brass. Lightly lube neck area to be with
a sizing lubricant (I used Redding Imperial Sizing Wax). Start
with 357/44 B&D sizing die set up high, screw the die down
while checking to see if the tapered shoulder and neck are formed
(and fit your chamber!). Lock down sizing die and run other cases
through. Check case length, trim if case is too long
for chamber.
Neck Length
It is about .150 long, so you cast boolit shooters may be
limited as to boolit length.
Case Capacity:

H2O, the 357-44 B&D is 33 and the 357 Max is 33.6 The AMP
shows a lower pressure at 37k with the Max at 48k.
Powders
Most loads use WW296, H110, IMR4227, Unique, or Blue Dot.
Accurate powders listed are No 7, No 9, and 1680. The Alliant
Power Pro 300-MP information is included for my own
investigations. As of right now, I have not found any official
loads from Alliant for the 357/44 B&D, the 357 Remington
Maximum, or the 357 AMP rounds.

The only data that is from a manufacturer on this page is the
extract from a Hornady Handbook (357/44 B&D), an extract from
Speer #9 Handloading Manual (357 AMP), and Accurate (357/44 Bain
& Davis). The powder charges in the articles are from the
powder lots produced at that time. We all know that even old
timers like Unique, Bullseye, Blue Dot... have undergone changes
in density and formulation over the years. Do not assume that any
of the maximum loads are safe to plug into your gun without
working up from a starting load.
