Can use my.40 for my 10mm?

[Tristan]

Okay. So I'm trying to learn this reloading bit, doing pretty good. But I forgot to order bullets for my 10mm and I am out of my normal Hornady XTP. So, the question is, can I use my 180gr brass jacketed hollow points (Remington) for my 10mm? I have been using these for my baby eagle .40.

10mm-Glock 20, 6" barrel
Normal load; Hodgdon Longshot 9.5gr, Sierra Brass, CCI 350 primers, 180 gr Hornady XTP

Yup... same bullets are fine. Only thing that I would not do is load plated bullets into 10mm due to its power but either lead or jacketed are fine.

.400 diameter bullets work in any .400 cartridge.

Where on earth did you hear that? Plated bullets pretty much suck at most all pressures when you are looking for accuracy.

The last thing I would use in a 10 is lead.

Lead should shoot fine in 10mm (though I wouldn't shoot it in a glock or other polygonal barrel due to the fouling).

Jacketed is obvously best.

Plated sucks at anything stronger than plinking loads. High pressure/velocity and the plating can come off.

"Should..." Lead bullets can be anywhere from soft with crappy lube to hard with good lube. When you start running a 10mm up there, soft lead will really foul a barrel. Even worse if they use crappy lube and you use a hot powder.

If you are shedding plating, you are using too much crimp.

Bullets for 40 and 10mm are interchangeable. Should be able to find load data for both calibers.

I load 180 gr in my 40, which would also work in 10mm. Been thinking about getting a 10 mm, since I have everything I need to load it minus the brass. :)

I avoid lead for all my bullets. I load for too many semi autos to make it worth my time buying lead.

Wow, there's a lot of misconception about handgun loading and bullets out there. You guys really need to listen to Hoser on this one. He's pointing all of you in the right direction.

Hmmm, sounds like another info thread to do in the near future.

Std bullet diameter for both 40S&W and 10mm is both .400. Pushing a 180gr jacketed bullet out of a 10mm is typically fine.

Hmmm, I find this to be exactly the opposite. I shoot moly coated lead bullets by the case. I load and shoot too many semi autos to make spending all that extra cash for jacketed to be financially worth it.

40 S&W bullets
180gr Montana Gold FMJ's is $295 a case (2500, 11.8 cents a round)
180gr Black Bullet Int. Moly coated lead is $203 a case (2500, 8.12 cents a round)

On an average year, I'll shoot 30k of 40 S&W
That's $3540 for Montana Gold bullets per year.
That's $ 2436 for Black Bullet Int bullet per year.

Total Savings of $1104 per year on bullets alone.

They're just as accurate, don't leave leading or deposits in by barrels, take less powder to push to equal velocities, and wear less on my rifling resulting in longer barrel life. BBI bullets are a little bit harder to get the dies set right for, but once set, load as fast as jacketed.

Not only is it worth my time, it appears they are the better choice. At even 50% the savings, it would appear worth the savings to drop $200 for a replacement KKM barrel for my 9mm glocks to shoot moly or lead bullets.

I have too many Glocks. I've often thought about getting a different barrel, but never really went farther into then that. I also don't shoot nearly as much you. This past year I've only gone through 2k rounds of 45. Just been too busy with everything else.

Might have to look into the moly coated lead bullets. Never gave any thought to them.

Lone Wolf barrel is about $100, have them open up the chamber a tad for another $20. Then shoot the lead or moly bullets all day long. I usually break in new barrels with a couple hundred jacketed before running lead/moly through them and it helps smooth out the machining of the lands and grooves.

I know some shoot moly bullets out of Glock OEM barrels and have no issues. Others do so and have problems with leading. It's really hit and miss. Harder lead is better than softer for this, good lube is essential, and the bullet cannot be undersized even by .005" or you will get leading. Undersized causes gas shearing around the sides of the bullets and leading is instant and severe. It's fairly cheap to test it out though.

230gr Black Bullet International moly coated bullet are what I wold suggest trying out.

4.2gr of Solo 1000 or 3.8gr of Clays
1.255 OAL
any brass
Fed/Wolf/Win Lg pistol primer

Load up some and shoot about 50 of them. Then pull the barrel and check. A little moly in the barrel will come right out. Even a little lead is pretty easy to get out with a 5 minute soak of the barrel in 50/50 mix of hydorgen peroxide and rubbing alcohol. Just make sure to only soak for 5 minutes and get it really dry afterward. It will peel the lead out like nothing else. Lots of leading, I would stop there and not shoot lead or moly out of it.
