Plated Bullets in Glock Barrel?

[HighLander51]

I shoot 124gr almost exclusively in 9mm. It was the weight that 9mm was invented in. To me it's the perfect compromise of the 115gr and 147gr bullets.

Actually the 9mm was based on the 115 grain bullet.

[HighLander51]

When I was shooting competitively, 4.4gr of 231 under a 124gr plated bullet was my go to load. Shot around 80k of those in 4-5 years.

Why did you stop?

[Low-Pressure]

I've used Berry's and X-treme in my G34 and have not had any problems.

[EWILKE]

YES

I have been doing it for 15+ years and never had a problem.rarely even see copper fouling in the barrel.

Can you please give me some references for this informatoin. I've done extensive research on the topic and always read that the original was 124gr. I just did a quick google and this is the first thing that popped up:

The earliest loads have FMJ truncated
cone bullets weighing 124grains. These were
replaced in Germany with 124grain FMJ bullets
with a round ogive in 1915-1916 (Figure 3)
though truncated cone bullets were used on
commercial loads in the United States into the
1930s. Later, round nose FMJ 115 grain bullets,
usually has a concave base were introduced by a
number of countries including Britain (Figure 4).
During the early stages of World War II...

Got burned out. Got tired of the gameing and watching IDPA become USPSA lite. Got tired of the politics and bans/registrations coming down in 1999-2000. So I put all my guns in the safe, locked it, walked away and didnt open the safe for 8 years.

Why did you stop?

I've been using Xtreme plated bullets for the past four years in a variety of Glock 9mm platforms, including the G17. All tolled, about 4K of them. Way back in the early 1990's it was not uncommon to run hard cast lead bullets in a Glock. I've never had a single problem with any of them, lead or plated. No pressure problems nor any residual metal in the barrels. The barrels have cleaned-up easily w/o having to use anything other than Hoppes #9. Powders used have been Unique, Titegroup, HS-6, VV-330, and Power Pistol.

I'm part of the 124 grain crowd but routinely load 147 grain bullets for accuracy testing and competition. Both Xtreme. In side by side testing about a year ago, my G17 and G19 printed amazingly small groups at 15 yards with the 147's compared to commercial 115 grain ammo and my own 124 grain RN handloads. At first, I had a hard time believing the group size could be so much smaller with the 147's.

I inadvertently picked up a couple of boxes of 124 grain FP (flat point) Xtreme's in 2009 and have since loaded several batches. While they look a little weird seated out to 1.070" they actually seem to fly better than their RN cousins with improved accuracy. As with the 147's, I tend to believe the longer bearing surface of the flat sided FP works better with the Glock's polygonal rifling. Or maybe it's just the longer 147 grain bullet that matches up better with the barrel's twist rate.

All primers are CCI #500.

I run the 147's with VV-330 at about 900 FPS or with Power Pistol at 950 or 1000 FPS by adjusting charge weight. For competitive matches, I use P.P. loaded for 1000 FPS. I believe in using standard velocity loads. COAL=1.142 with Win brass. They worked great at the GSSF match in Piru a couple of weekends back. Finally, no missed shots.

I run the 124 RN and FP bullets for most everything else, including IDPA. While I have done a fair amount of experimenting with other powders, these days my go-to propellant is Titegroup loaded for 1100 FPS out of the G17. Slightly slower in the G19 @ 1060 FPS. Titegroup is super efficient and clean burning with a low SD. COAL=1.120"

My 9mm loads started with data found in the latest Sierra manual. Cycling issues with any of the above configurations, 124 RN, 124 FP, 147 RN: NONE.

I use both Berry's and Ranier 115 grain plated bullets with no issue.

Thank you all for the great information!

I just asked a caliber expert on another forum I frequent. This was his response.

The original load was a truncated FMJ. The original weight varied from run to run of ammo by a couple grains. They typically weighed from 123 to 125 grains.

You are correct. A lot of European nations use lighter projectiles these days for their military NATO spec ammo. You can find 112 (Winchester made that weight at one time as well), the Canadian is 116 grain and the Dutch was 114 but was speced to 115. That don't mean squat though. The original weight averaged out to 124.

Still interested in if you have other sources Highlander.

I'm a 9mm nut, and have actually heard many times that the original was 115gr, but they were always from inaccurate sources. I have some ammo from the 30's I think in the garage. Maybe some from the 20's. I'll look later.

8 years that's too long not to shoot!!

[bluenoise]

I need some specific OAL and powder charge data so I can give these plated bullets a try with the components I have. I have W231 powder and Winchester primers. Now I need to know that data for each of my bullet types (115 RN, 124 RN and FP, 147 RN and FP).

Thanks!
