340PD Ammo for Self Defence

Cor-Bon 125gr JHP .357Mag, 1450fps.
Speer Gold Dot 125gr JHP .357Mag
Federal Hydra-Shok 130gr .357Mag, 1300fps

For .38spl, since I use only jacketed ammo I am still working on this one myself.
 
KC,
Are those chrono'd velocities? If so, I want your gun :D
Hornady 125 gr JHP's are around 1500 fps...from what length barrel I dont know. It sure kicks from my SP though...
Shoot well
 
I don't have notes handy here, but recall that when initially testing various ammo for mine, about 8 out of 13 "jumped the crimp" to one degree or another. I do recall that Winchester Silvertip in .357 was enough to be scary. Unfortunately, some Gold Dots in .357 moved as well. I do recall those two brands in particular because I have some new (expensive) partial boxes still sitting around! Did not get to test any Corbons.

Due to vicious recoil and shot recovery time, what I settled on for now (since testing back about January/February) is Gold Dot .38+P 125s and/or Federal Classic .357 125 JHPs.

FWIW, my 340 is currently keyed up with 3 of the Gold Dots +Ps, then 1 .357, then 1 CCI shot load. One shot load is kept in gun this time of year to be able to back up one notch if needed for a snake, which we have lots of where I commonly hang out. About Novemeber, I'll likely go back to keying up with 3 +Ps and 2 .357s.

In any event, be sure to read and heed what S&W instruction manual says about testing whatever you may want to run with. Greatest probs obviously with unjacketed bullets, but mine was not limited to them. Hope this helps a bit. Regards, Greybeard

I guess you can say I cheated, these velociteis were chrono'd from 6" barrels. Out of a 2" barrel the numbers are more like 1180fps and 1090fps, at best.
 
I have a box of Winchester Super-X .357 amgnum 125 gr JHP -

X3576P. Can anyone tell my the ballistics in terms of foot/pounds
of energy for this round?

I'm going to test this in my 340PD.


Also, how many ft/pounds is considered a "hot" .357 load?
 
From what I chronod a couple of years ago..most "Full House JHP" mag rounds from a 2" were around 1200+ FPS..and had 400+ FPE ...that is HOT! If you find something in this ball park or hotter...post it. I dont have any of my notes from our "shoot" but remember Federal Classics were pretty potent. I would love to test Corbon, Triton, Gold Dots etc...from my current guns.
Shoot well
 
I use the Proload 125 gr. 357 mag tactical lite (rated at 1125 fps out of a 4-in. barrel). These are lightly loaded and fairly manageable, but still beat most 38 Spl +P offerings (I don't know about Corbon's +P+ loading). I've never had any significant bullet creep within a single cylinder full (5 rounds), though suspect serious creep would eventually occur if the 5th round were never fired, and subjected to multiple cylinder firings of the first 4 chambers.
