Colt 357

I have a Colt 357 Magnum Trooper Mark III from the early 70's. Will this gun shoot .38 rounds? I've been told that it should but when I load them, the hammer will not pull back.
 
If the gun works ok with .357 ammo, it should with .38s.
That's .38 Specials.
There is a lot of .38 ammo out there, not all are .38 Special.
 
May be the problem then. It has to be .38 special, correct?

I just checked and they are definately .38 special rounds. Does it make a difference if they are reloads?

Seems like only if they are not loaded correctly. High primers binding the cylinder maybe? I assume if you cannot cock the hammer that it will not advance in double action as well?
 
Who made the reloads? If they are factory reloads then they should be fine. A security company I worked for many years ago bought 3M Factory reloads for range courses. They were dirty but did fire reliably. If they are made by a private person then quality could be just about anywhere. There are some good reloaders and some terrible reloaders. If you are going to use reloads the get the factory reloads unless you know the reloader extremely well. The other option is to do your own reloads. It is not all that difficult to start. The 357/38 combination is a very easy caliber to start out with. All you need is a good press with a good set of dies, an up to date reloading munual, proper powder and a good powder messure and time.
 
The reloads are from a very reputable dealer in Georgia. I also got some .357 cowboy loads from them and they work fine in the gun. I have examined the 38 rounds side by side with the 357's and the only difference I can see is the length. And yes, the issue is that the hammer will not cock with the 38's loaded.
 
Reputable reloader in GA?

That doesn't answer the point about high primers. Do you have a caliper? Measure the rim thickness. Place your .38 Specials on a flat surface and see if it rocks. If it rocks, then your primers are high and they are interfering with the cylinder's rotation.

Thanks Gary, I'll try that. Don't have a caliper. Do you know something about GA not having decent reloaders? I'm new to this so maybe I was given bogus advice.
 
A good rule of thumb in these situations is, when a firearm works fine with most ammo but has a problem with one batch of reloads......it's the ammo.

A sure way to find out is to buy some factory new ammo and try it.
If it works, the problem is the reloads and a smart shooter will discard the problematic reloads, or break them down for the components to be reused in better quality reloads.

A not so smart shooter will try to use them, possibly in another gun.
If the reloads are bad enough they won't work in one gun, that's a pretty sure sign of a poorly loaded batch.
Question is, what ELSE may be wrong with it.

The what else can take the form of "Oops, I just blew my expensive gun apart" or "Oops, I just did serious damage to my hand or lost an eye", or "Oops, the poor guy standing next to me just got hit in the head with a piece of my gun, wonder if he'll sue me"?
 
Insert .38s, close cylinder, with finger off trigger pull hammer back just about half way to lower the stop bolt, see if you can easily turn cylinder, repeat easily turn cylinder.

Old-time shooters, i.e. the likes of Bill Jordan, used to do this just to make sure nothing was going to bind the revolver for those first all-important six rounds.
 
Could be they were not resized properly and are not seating all the way in the cylinder put a factory 357 in one cylinder and one of the problem rounds right next to it. They should be level with each other.
 
Thanks for the help everybody. I'll try it all and see if anything works. The stuff works well in a .38. Well, at least the rounds I've shot so far have.
 
I don't mean to knock commercial reloaders in GA. It's just that the reload may have high primers and this would interfer with the cylinder's rotation.
