I have a 9" 357 magnum barrel that has become the latest canidate for a rechamber. [Eek!] I am open to suggestions, currently thinking along the lines of 357x44mag, 357x445sm, etc... First thought was a 357x444 Marlin but with the short barrel length it would just be blowing a lot of powder out the barrel. Dies ARE NOT A CONCERN! I have a set of 357 magnum dies that will make the trip with the barrel to OTT to be modified. [Wink]

Look forward to readin you INTERESTING suggestions!! [Big Grin]

EDIT: Would prefer to stick with a rimmed case but ALL will be considered! [Smile]

An original 357/44 Bain and Davis.... not the soft shoulderd latter desgin we all know now. 357/44B&D improved... (but since it would be the old design, it would be "re-improved?") Where you'd find a real reamer I've no Idea. Just run a 357x444 reamer in half way???

I only see one choice in your life with that short barrel.

Can you say 357 Max?

Just a cheap internet opinion of course.

I like the idea of a 35X445.....I think you could use a Bain and Davis reamer and run it in a bit farther for the 445 length. You could probably use a B&D sizer to resize the neck and shoulder and a 44 mag die to resize the base.

seeing that it is a 9" barrel all you need is the .357x44mag you will never get all the powder to burn that the other ones can hold. and all you will end up with is a 9" flame thower.

Since you already have a max, I'll also say the 357X445 sounds like an interesting one.

Since you already have the brass, How bout a 35x41 or a 35x414? Both the 357mag and 41mag case length are 1.290.

Hey there "BIG SHOOTER" you just go right on and chamber what ever ya want. I vote for the 35x444 with a brake. That should give you a few usable inches of barrel [Eek!] [Razz]
Make a neat conversation piece if nothing else.
BTW, whatever kinda animal you make out of it let mbm be the first to "blood" it again [Razz]

That's a .356 GNR.. A .41 mag to 357. Supposed to work nice in Ruger Blackhawks... might be fun in a 9" T/C

357 Herret , my personal all time favourite in a Contender! Easy to make , dies are fairly cheap and it has enough case volume for your length , but that`s just my 2 cents , J�rgen

I'm with Jurgen,
If you don't want to go with the Max because you already have one...but really one's not enough, I have 3... I'd go with the 357 Herrett too.
Not sure if your barrel is being rechambered because it lacks power, throat is no good, or you are just bored and ready to move on, but that would make a difference in what I'd recommend. If you don't like the throat, going to 357X41Mag or 356GNR isn't going to fix that, due to no appreicable change in LOA of the cartridge.
What ever you choose, I hope you have fun with it...life is too short.

regards,
Graycg

Another thought,
How about necking up the 30 Bellm to .357? that would be very similar to the 357X445 and you could buy the 30 Bellm brass from CNC and then just neck it up? That would give you a 1.4" long case, cleans up the throat if you want and brass isn't too expensive or complicated to make?
Hmm, maybe I need one of these too...

Graycg

Mark,

Unless custom or a reamer is modified, this won't work. The B&D reamer will have the rim counterbore on it, thus you cannot run it deeper.

You can grind off the rim counterbore. Then it could be run deeper.

The .445 case would be a bit much in a 9" barrel, imho.

Gene, this would work so long as dies are not an issue, as he stated. But it gets simpler on one hand. No need to neck up, just don't neck down so far. But on the other hand, it would require me to make up a .35 cal. neck ream die.

I have thought about doing a .35 for the Illinois folks to meet their 1.4" case length restriction, but this would not give as flat trajectory as the .30 cal. does. The object was to give them a good 200 yard trajectory, and smallish .35s probably would not be as good in this department.

However, for case strength, .444 Marlin cases are hard to beat. I doubt the .445s are as heavy as .444s back toward the web.

Hope all is well with you and your crew, wherever your duties have you!

Mike

I have a 357mag barrel and also a 357max, just want something different! [Wink]

This barrel is an old "short throat". I thought of that when thinkin of the 357x41mag. The only question is the alignment of the chamber to the bore at what will be the new neck area. I think that i will box it up and send it to Mike S, have him check the "runout" and then make my decision.

Regarding runout, it is a good idea to check it, yes.

For example, yesterday while a visitor was here, I rechambered a .357 Herrett barrel to .358 Bellm. (Yes, if you are waiting for one, yours is coming. There is only one left to do.)

I dialed in the bore to less than .001" runout. It then took .010" to clean up the runout in the mouth of the chamber just in front of the rim counterbore, which he got to see for himself first hand instead of having to just take my word for it like most of you are expected to do.

BTW, the door is open anytime anyone wants me to demonstrate this, though any good local machinist can do it quite readily also.

Do not worry, however, about the alignment of the neck of the chamber. The neck is not what does the real work. What does the real work aligning the bullet with the bore is the throat.

Inspite of the misalignment of the chamber with the bore and the current misalignment of the short factory throat with the bore, extending the throat with a minimum diameter throat reamer with a long leade angle, then seating bullets out into this new throat area, will give very positive alignment of the bullet with the bore.

Any remaining misalignment between the neck area and the new throat area that is cut is not an ideal situation, but the new throat makes the rechamber in even some of the worst cases of misalignment still quite viable.

It is the throat that counts, not the neck.

The neck does some work, but very little compared to what a minimum diameter, long leade angle throat can do.

It works. [Wink]

It matters quite a bit in this instance. If the chamber is running out, i will just use the larger case. This WILL remove the existing "neck" and eliminate the runout.

.41 Mag and .44 Mag. will not cut out the existing .357 Mag. chamber neck, btw. You can lathe bore out the runout where the larger part of the chamber will be, but the neck will be the same.

I agree that a neck aligned with the bore is obviously more desireable, but 24 years experience chambering barrels has shown that the throat can and does compensate for misalignment in the body and neck of the chamber.

You will have at least .003 or .004" of clearance around the case neck. Think about it. Realistically, what can that loose of a fit of a thin brass tube do to align a relative rigid bullet while it undergoes the forces involved in engraving the riflings into it?

On the other hand, if the bullet measures .358" in diameter, and the throat measures essentially .358" diameter, does it not stand to reason that a tightly fitted steel tube will align and support the bullet better than a sloppy hole and thin brass tube?

The throat is the key, but everyone is geared to not thinking along this line. It is just not mainstream.

The misalignment in some of the factory chambers would really shock you if you saw it for yourself, yet with the throat lined up with the bore in the rechambering process, they nearly always shoot great. It is the throat that counts most. So even if there is some runout in your chamber, focus on the throat and you will get good results.

That is pretty much a "no brainer". In my previous post i meant to say "longer" not "larger". Obviously if a 41mag case will not remove this "neck" a 44mag case wont. A 414 case on the other hand will remove the whole works, thus my point above..... I would much prefer an on center chamber than a throat to compensate for the lack of it!

Now you're "cookin'" and we are both on the same page of the hymnbook. [Wink]

Yep, the .414 case will give you the added length you need to cut forward of the existing neck. And like I said, inspite of runout in the existing chamber, you can still get a precisely aligned new chamber by lathe boring out the runout in the existing chamber since it is enough smaller in diameter to allow doing so.

Then, with the bore running true, the new .35 cal. neck you cut can be aligned with the bore ok. Follow it up by doing the throat as a last, separate operation to keep the throat tolerances down to a minimum, and with no interference from torque forces cutting the body of the chamber, the throat will be better centered with the bore.

Absolutely..... align the body of the chamber with the bore if at all possible. But there are situations such as with going from .357 Mag. to .357 x .41 Mag where you cannot correct the chamber body alignment and the throat can and will compensate for deficiencies behind it.

With the longer .414 case, you can get the best of both worlds! Like it should be!

Please don't take the details of this post as talking down to you, but rather detailing the process for the benefit of those who do not quite comprehend what the hole in the breech end of the barrel is all about.
