Missouri Bullets for 9mm Parabellum

csdmann · #1 03-23-2013, 10:18 AM

I have only reloaded Hornady bullets/projectiles for my 9mm. I shoot a Glock 34 and a Beretta 92. I would like to try Missouri Bullets and have a couple of questions. I noticed the Missouri has a .356 diameter. Hornady has a .355 diameter. Is this ok? Any difference in the Missouri being a lead type of bullet vs Hornady being a jacketed type of bullet? Is Missouri bullet going to "lead" my barrels? Can I use the load data out of my Hornady reloading book?

You need to read up on lead bullets and reloading them first. Lead bullets are typically .001" larger in diameter than jacketed bullets, sometime more. So yes, they're okay

Are your Hornady's "jacketed"? Not sure what you mean by "coated."

Lead bullets "may" cause leading, may not. That depends on several factors: bullet hardness, powder used, velocity achieved, etc.

I use Missouri 9mm 124 grn RNs and have no leading problems are mid-range powder levels, minimal leading at worst. Given equal weights, lead bullets will use less powder as they have less barrel friction. Keeping lead bullets under 100 fps will help avoid leading.

Missouri is advising customer that it will be 3-4 weeks for delivery. The prices are good, especially considering the quality of its product.

The Hornady is most likely a swagged bullet and coated with a moly lube. The smaller diameter will allow the softer Hornady bullet to upset slightly and fill the bore when shot. The Missouri bullet is cast and is of the correct .356 diameter for 9mm. My experience with both is the Missouri which is lubed also will shoot just fine as will the Hornady which is a softer lead. Both will do fine which ever you chose. You are only talking .001 difference. All lead bullets will lead the bore if driven too fast and hot. Keep the pressures and FPS within recommendation of your reloading books and you will have little problem. You might check Lyman Cast Bullet Handbook for cast lead bullet load information. Hope this helps you.

Missouri makes fine bullets, and they are about all I use. I prefer the 124 grain truncated cone, and they work fine in my pistols. Glock recommends against the use of lead bullets, but there are numerous folks who shoot them without incident.

Watch your 92 barrel. The Italian designed guns sometimes have very large bores. I had one that slugged out at .357 in a 9mm. I never could shoot cast out of it because of keyholeing and extreme leading. Also watch that glock barrel for lead buildup. On the Missouri bullets, there the only ones I use when I don't feel like casting my own. I shoot IDP #8 135 gn. Lrn from Missouri out of my XD9s. They are for 38 supers but I like my stuff cast at .357 for 9mm. I drive them fast with a fast powder charge of bullseye. They shoot great and get almost no leading.

Howdy,
I run 7.5 grains Blue Dot and Missouri's small ball 125 grain,.356 in my AR-24.
I can't say there is no leading, but I clean it between matches and it is not very bad at all.
I'd guess it to be around 1100 FPS.
Things might not be the same for you and your gun but a lot of 9mm, 38Super and .40S&W shooters have good luck with quality cast bullets.
Good luck
Mike
