Strange Info!!

[Taurus627]

Well guys, just picked up a Smith and Wesson SD9ve and of course I want to get into doin some reloads. Now the gentleman at my local gun store where I purchased the 9mm told me that I can use .357 bullets in my 9mm loads. I found this a bit odd as 9mm equals .354" or .357" is equal to 9.07mm.

Has anyone tried this? I know the difference is small but I am not willing to chance it if it will do damage. I do have a large assortment of .357 bullets from loading .357 mag and 38's.

Any recommendations are greatly appreciated.

9 mm jacketed bullets are 0.355" and cast bullets are sized to 0.356" according to Hornaday and Speer (jacketed) manuals. Lyman manual gave data for jacketed and cast bullet diameter.

Generally, reloading manuals have more correct information than the gunshop guy. The most difficult to speak words in the English language: "I don't know".

I have a ruger 9mm/357, when using the 9mm I have used 357 lead bullets at 358 size, 125 round nose as my pipe is a 357 and a 9mm bullet at 355 will tumble on me at 21 feet. I have had no problem reloading the 125gr 358 lrn bullet in the 9mm case and in my ruger the bullet does not tumble Charlie

I shoot .358 diameter 150gr LSWC in my P85
works just fine

Did the LGS moron happen to have some .357 bullets in stock?????

Do yourself a favor and just buy 9mm bullets, the aint the same.

 

[mtgianni]

What diameter did your bbl slug at? Mine require a .357 diameter.

for once ... we agree.
I suppose one could put some 357's through a sizing die to bring them down to the 355 356 as needed but youd still find that crimp groove in a location where it may cause issues with your head spacing

I have tried a few 9mm in my 357 mag with poor results......

Not having slugged my 9mm, I never tried the 38 cal. bullets in my 9mm auto.

INFO?

Hmmmm? Lets see here. LGS has maybe a few K invested in the store, at most. On the other hand, I dare say MILLIONS are spent by those that publish reloading manuals, including testing etc. Now, -- who??? might you want to believe?????

9mm v 38 bore

If you shoot a .002 over jacketed bullet-sooner or later something has got to give. That big bullet puts 3 times the drag on the barrel. Look at barrels blown off lately & sometimes the threads are still in the frame. I size my jacketed bullets to the od of the barrel bore if they are to big. Some people like to shoot .001 over on lead. I make all my lead bullets extra hard & size to the bore in rifle-revolver-& automatic - unless I am shooting a hbwc. Lead goes down the barrel much easier. Slug the barrel then you will know which bullet is best for you. BY THE WAY- all of my automatics are taper crimped. One of my 4" 38 S&W would not group well & come to find out the barrel is .358. Another one of my 38 specials is .355 & now it doesn't lead up anymore.

Sizing doesnt quite have the effect on pressure people think but Jacketed I wouldn't exceed 0.001" over bore. Lead is different and doesnt take much pressure to swage, chances are you'll run into chambering problems first. I have run 0.358 lead in 0.355 38 super barrels at major pf.

Actually, yes they did, and just about any other caliber.

Got to agree, but being new to these semi auto calibers, I figured it couldn't hurt to ask. Been doin revolver stuff for years with a bunch of success, so now it's on to 9mm and .45 acp.

P.S. Yea, Mr. J. R. WEEMS, I have the books and have actually read them, no need to lecture me and insult my intelligence on who I should believe or get my info from.

Thanks guys!!!!

For a new reloader, just stick with same/same. Purchase 9mm bullets to reload your 9mm handgun. But, I shoot lead and plated in my 9mms and most of the lead run .358" and about half the plated are .357". We don't know what context the feller at the gun shop was referring to suggesting a .357" bullet so badmouthing him is even more stupid than what some think he said! A 9mm bullet isn't always a 9mm bullet, and an awful lot of 9mm guns aren't what they're supposed to be, ie.; 9mm (my new 9mm's barrel is .357"not .355"). I use a .38 Special bullet (125 gr. RNFP @ .358") in my new 9mm.

To know what to shoot in your gun, slug the barrel.

No insult meant- Just cannot figure why one might ask such a question. Being a shop owner does not make one an expert. I ran mine over twenty years and can think of no reason to offer up such advice. Time to chill out I expect.
