Salutations,
I'm looking for an alternative to Speer's 357 Mag Short Barrel 135gr ammo for my 340PD. I don't think I've seen it in stock anywhere in the many moons I've had the gun. When I got the Noisy Cricket (340PD MIB reference

) I picked up whatever I could find and it just happened to be 140gr Hornady LEVERevolution ballistic tip which is obviously a terrible choice for the gun, although any ammo beats no ammo when duty calls.
Anyone have any good suggestions for good modern carry ammo for the 340PD?
.357 Magnum only please. I do not ever intend to fire .38s out of this highly exotic and rare no lock feather weight Magnum. I realize people love to shoot .38s out of it and +ps, but if I was going to go that route I would have bought (3) differing .38 Js for the price of this exotic hand grenade.
Thank you for your time and thoughts.
Other than these rounds,
For Expansion\Penetration\Barriers
Speer Gold Dot 135 gr
Golden Saber 125Gr
I would carry 158gr LSWCHP in magnum if barriers aren't a concern.
I wouldn't carry 357 at all in that thing. The recoil, flash, and noise aren't worth the added penetration. That's me. but if I had to the three above loads.
I did handload testing out of a j frame and an LCR here is what I got:
Handloads:
So I did a direct comparison:
Reloaded the highest book loads for the 135gr Gold dot for 357 and 38 +P.
I used the same powder, Power Pistol
Quote:
135gr Speer GDHP Short Barrel 6.0 gr Power Pistol 38 +P
Speer's Advertised factory velocities are 860 fps
The book has this load at 983 fps out of a 2.5"
1.875"
High - 908.7
Low - 830
Avg - 875 FPS - 230 ft lbs energy
now the high end:
Quote:
135gr Speer GDHP Short Barrel 6.4 gr Power Pistol 38 +P
Speer's Advertised factory velocities are 860 fps
The book has this load at 1065 fps out of a 2.5"
95 degrees
1.875" barrel
High - 1108
Low - 1031
Extreme Spread - 77.66
Standard Deviation - 38.88
Avg - 1066 FPS - 341 ft lbs energy
So that's a 191 fps 111 ft lbs energy difference between the high and low 38+P loads. Definitely a difference there.
Now for the 357:
Quote:
135gr Speer GDHP Short Barrel 9.6 gr Power Pistol 357
Speer's Advertised factory velocities are 990 fps
The book has this load at 1137 fps out of a 2.5"
95 degrees
1.875" barrel
High - 1395
Low - 1318
Extreme Spread: 76.73
Standard Deviation: 33.22
Avg - 1348 FPS - 545 ft lbs energy
The difference between the low 38+p:
473 fps 315 ft lbs energy
the high 38 +p:
282 fps 204 ft lbs of energy
Now the 38+p is much easier to shoot as the 357 is a handful. It borderline hurts. But it is controllable The 357 definitely packs more punch. There is a difference out of a snub nose. . I think my hand would fall off if I shot those loads out of a Smith lightweight like the 340 though. but I practice a lot with my training ammo. I have since went to 642/442 as I determined 38+P is more than enough to get the job done based upon actual NYPD and other sagency street shootings, gel tests and real life moving and shooting with recoil.
INMHO the bark is not worth the extra bite. If I want extra bite, I carry the charter bulldog 44 spl which has way better recoil than even +P 38
I gave temps because I live on the sun and things travel faster near sea level in high heat. these wer all shot about 1800 above sea level for reference.
Hope this helps.
