Smith 57-6 41 mag will shoot!

[dogdoc]

I shot a few 6 shot 25 yard groups yesterday with my smith 57-6 41 magnum that I picked up this past year. Those groups are about as good as I can hold. I always have one out of six that opens the group up a little but that is likely me. I define good six gun accuracy as 2 inches or less for 6 shots at 25 yards. If I did best 5 of six I would have many an inch or less which is what most do. With a five shooter I do five. Gun is well put together and finish is good.225417225418225417

I've never seen a model 57 that wouldn't shoot good groups, I haven't shot the model 58 I just received yesterday.

You’ll enjoy that 58. I’ve got one and it’s a constant range companion. 7gr 231 with any 210-220gr will do anywhere between 875-950 depending on gun from the chrony results of 4-6.5” barrels

Smiths in .41 Magnum always seem to shoot good...

Found a 4 cavity Lyman 410459 that cast a good bullet at about 220 grains that shoots well in that sixgun with 7.5 grains of unique. I have not had the leading problems some report with newer Smiths but I shot several hundred jacketed through it. I hate to admit it but a 215 grain magma mold type commercial bullet shot great with a midrange load of accurate number 5 .i usually dislike the commercial bevel base bullets but those shot extremely well in the 57-6 classic. Going to try some 41 cal 220 Keith bullets from an arsenal mound with 19 grains of 2400 and see if they will hold 2 inches or less at 25 yards.What are others accuracy standards for sixguns ? Just curious

This is 10 shots using the saeco bb 215gr commercial with 7gr 231 at 25 yards using my PC hunter model on a rest.

Is that the old style rifling or new?

Old or new in a S&W???

I don’t know. It doesn’t have the 2 piece barrels they’re selling nowadays on some of their models

My 57-6 classic has sharp looking rifling unlike an older ecm rifled 625 mountain gun I have that has rounder looking rifling. Surprisingly the 625 does not lead badly. The new 657-6 I have may be ecm type but it looks like broach and shoots lead bullets well. I do think you need to shoot several hundred jacketed bullets through the new guns before going to cast.

[S.B.]

dogdoc, please, explain ecm rifling? Acronym for what or something new? I, for one, have never heard of this(i'm 70 and have followed S&Ws for most of my life)?

Could mean EDM (Electro Discharge Machining) where you use current pulses to cut a barrel to match the rifling button, instead of using mechanical force to cut? Not certain but I've seen EDM used a lot and not heard of ECM; Typos happen!

[S.B.]

Yes, I understand Electornic Discharge Milling but, don't remember any discussion of this with S&Ws?

It is actually electro chemical machining. There is much info on it if you google ecm and smith and Wesson. What I have read is that they started it in 1993. Some say it is more likely to lead than broached barrels. My newer Smith’s seem to be fine but I like to shoot several hundred jacketed bullets before I start shooting cast

[S.B.]

Well. I did a search on ecm and Engine Control Module, enterprise content management, ECM Records seems like everything but, what you're talking about? Please, list a link? I have some experience at machining but, never done anything with chemicals?

Steve,
Although it doesn't reference S&W, I did find this to explain ECM:

obssd1958. I know the title and video said ECM but, looked like every other EDM I've seen work? Never even heard chemicals mentioned? Did you watch it?
Steve

[obssd1958]

Yeah, I watched it and several others. I wouldn't have posted it, had I not watched it :) .
At the very beginning they refer to the process being based on electrolysis. Later they mention that the "electrode" makes no contact with the workpiece "electrically or mechanically". Then "the workpiece in it's raw form is eroded, via an electrochemical process".

The following is from Wikipedia:

ECM is often characterized as "reverse electroplating", in that it removes material instead of adding it.[2] It is similar in concept to electrical discharge machining (EDM) in that a high current is passed between an electrode and the part, through an electrolytic material removal process having a negatively charged electrode (cathode), a conductive fluid (electrolyte), and a conductive workpiece (anode); however, in ECM there is no tool wear.[1] The ECM cutting tool is guided along the desired path close to the work but without touching the piece. Unlike EDM, however, no sparks are created. High metal removal rates are possible with ECM, with no thermal or mechanical stresses being transferred to the part, and mirror surface finishes can be achieved.

and is an excerpt from here:
https://en.wikipedia.org/wiki/Electrochemical_machining

I really know nothing more about this than the limited info that I have read, viewed, and passed on - due to your question!

I hope I've been helpful!

[dogdoc]

I will have to figure out how to post a link but if you google”ecm and smith and Wesson “ you will get info on it. I just did it.

[dogdoc]

Link of it works

OK so, how is S&W saving money here? Don't we(the customers) pay this cost? Doesn't make sense to me.
The price of S&W handguns steadily/constantly is on the rise. Actually, they've priced many out of their market along with less quality(IMHO).

[dogdoc]

I wish they still broached the barrels but it must be cheaper for them. I have several recent produced smiths that shoot well and do not lead excessively so I guess I cannot really complain.

I still remember shooting flat Coors beer in 12 oz cans offhand at 100 yards. My dear late friend had an 8-3/8" m57 shooting full house Sierra 170 jhc.
No doubt when one was hit!
