.357 magnum case slight bulging

[Border Collie]

hello everybody, i took my first test shots with my 6" colt python. using some .357 magnum reloads-not by me- and they wanted to stick in the cylinder, after i got them out i noticed slight bulging near the primer side of the case. is this normal for .357? thanks guys

It is normal for high pressure loads. What does the primer look like?

I would shoot some factory loads, so you know how the brass behaves. Don't shoot any more until you see how factory loaded brass looks like.

Ive loaded full blown max 357 loads using 2400 and 125gr jsp.
They gave a noticeable buldge on the *** end of the case, but surprisingly.. there wasnt anything funky going on with the primers... all looked good.

Did you by chance shoot 38 specials in the gun first?

Carbon build up from the shorter case will cause sticky extraction.

As far as the reloads I see nothing unusual.

The case head is solid and will not expand so the rest of the body fills the chamber.

the gun was cleaned an hour before shooting.

There is clean and there is really clean.

It takes quite a bit of effort to remove carbon from a chamber.

Much more time involved than most people are willing to spend.

If I told you how I remove carbon I would be told not to do it that way as it will damage the gun.

It is hard to completely remove and that is why I ask about shooting 38's.

It doesn't take much to cause sticky extraction.

The loads appear to be fine.

Even with the hottest load I have ever tried in the .357 I don't ever remember having sticky extraction. Hence the question.

It's good to ask questions.

i have never fired this gun, i just got it. i assume .38 was fired though it. i just slid the case in 5 and it was smooth, on the 6th it was a bit sticky. bet i need to run a brush though it again. after they were fired none wanted to just fall out.

Take a rod a brush and some bore cleaner. Dip the brush in the cleaner.

Place the rod and brush in a battery operated drill and spin it in the chamber.

I will bet you that black carbon will be coming out of the chambers for longer than you can imagine.

Just do one until you see that it is really clean and then you will understand how much build up can occur.

I assume that the gun was purchased used?

If that doesn't make the chambers smooth then there is always the nuclear option. I'm not sharing that but it is fast.

Have fun .357 loads are lots of fun.
