- EEEEEKKKKKK! You mean you have a pistol chambered for .357 Magnum
- and you are downgrading it to a 158 grain Lead Round Nose .38 Special?
-
- Why?!?!?!?!?!?!?!?
-
- OK, I can sort of see using a good strong .38 Special load in the
- .357 gun for routine defensive use (less recoil and less muzzle flash),
- but come on, a 158 gr LRN? You're pulling my leg, right? It's a funny,
- a joke, a gag, right ... ?
-
- A typical factory loaded 158 gr LRN is at about 755 fps for 200 ft-lb
- of energy at the muzzle. (Federal, Winchester, and Remington load this round
- to this level of ballistic performance) And a LRN bullet will not do much
- terminal damage, especially at that modest velocity, because that round nose
- just sort of squirts through the target tissue without disrupting it much.
- At such modest velocity/energy levels, you owe it to yourself and whoever
- else you are protecting to use a better ballistic shape, at least a
- semi-wadcutter. A LRN _might_ be easier to slip into a cylinder than some
- other shape (I have _never_ had aproblem slipping other shaped bullets into
- a cylinder), but it also just slips through tissue easier too. Which is the
- same reason that a FMJ (usually round nosed) bullet is also a poor stopper, the
- shape is just poor from a terminal ballistics standpoint.
-
- If for whatever reason you have/want to stay with a standard pressure
- .38 Special round, look for a semi-wadcutter bullet or similar shape. Don't
- use a LRN pistol bullet for defense, it's just not that effective. Better yet,
- try a .38 Special +P, like 158 grain LSWC at 915 fps for 294 ft-lb muzzle energy.
- Or even better in that gun, a 125 grain JHP at 1450 fps for 583 ft-lb of muzzle
- energy. :-}
-
- Don't unduly handicap yourself with your ammo selection. In .38/.357 rounds,
- the 125 grain .357 Magnum at 1450 fps is currently considered a "good" stopper
- of man-sized targets. Lesser power/weight/velocity rounds in this bullet diameter
- are less effective as stoppers on man-sized targets. The round nose pistol bullets
- (LRN or FMJ) just penetrate straight through and don't "STOP" the target very well.
-
- Please pick at least a different shape bullet, LRN is marginal for stopping
- people. (Unless you _really_ have some weird set of constaints on ammo selection,
- like subsonic rounds to be used in a silencer-equipped weapon for close-range
- head shots ... like the 147 grain 9mm subsonic rounds originally developed for
- suppressed MP5's for the SEALS, but that's a REALLY different set of operating
- conditions than a typical home defense scenario, isn't it? :-=} )
