There are a couple of tricks to magnum revolvers:
1) you can shoot light "Special" loads. For example, a .357 Magnum will shoot
.38 Special, and .44 Magnum revolvers will shoot .44 Special (about the same
energy as a .45 ACP, and what Dirty Harry said in the movies that he used - really).
.50 Magnum will shoot .50 Special (a little hard to find) and there are many different
loads of .50 Magnum - some have more kinetic energy than others. The hot ones
will have muzzle velocity (depending on barrel length) around 2,000 fps
You can't do that with an automatic! Not that many automatics will fire a magnum
load anyways - AFAIK only the Desert Eagle will fire a really powerful round, and it's
got this incredibly cool bolt that locks, sorta like an AR-15:
2) trick I learned with the .50 Magnum was to go to a bicycle store and buy the
most expensive riding gloves they sell. Throw out the left one. Wear the right
one when you shoot the .50 and the leather pad in the palm will spread out the
force nicely to a larger area. With a good leather glove, you can shoot .50 Magnum
all day long, at $5 a round. 100 rounds - not very much - is $500.
It's totally subjective, but I love .45 ACP ... other guys are in love with 9mm (yeah, yeah)
and there are plenty faster rounds, but there's something so perfectly balanced about
a 1911 .45 ACP:
A good day at the range starts like this. The trigger is unbelievable. Only thing I
can compare them to, is the ailerons on an Extra 300.
At some point in your life, you need to experience the trigger of a $4,000 custom
1911 .45 ACP, and the ailerons of an Extra 300. Neither will disappoint. Both are
exquisite achievements of engineering and artistry. Words fail me. Do it.
