Thick plated xtreme bullets OK for 10mm?

Nitrous SSC · Dec 25, 2014

So everything I've read on the good ole' "internets" says that anything past the 1200-1250 range plated bullets seem to have big issues. The other item I frequently came across is that warm 10mm's (1000+fps) tend to have bad accuracy with anything less than a 180gr.

If I loaded up some warm 10's with say, mid-upper 9gr range with longshot (I've got 3 lbs of it) would 180gr "heavy" plated be OK or do I need to spend the extra cash and get FMJ like Hornady HAP's? Velocities would be 1200+

10/40 - 180 RNFP HPCB

The other I was wondering about is "coated" bullets. Seems to be the craze lately at matches.

I'm using extreme 200gr at 1200fps in my g20sf with good accuracy. My gun seems to prefer aa#9 with them though. LS seems better with 165-180gr.

According to Xtreme's data

Bullet/Load Info

Our Copper Plated Bullets can be run at mid-range jacketed velocities or higher end lead velocities. We recommend keeping velocities to less than 1500 FPS (Feet Per Second) and using only a light taper crimp

Any velocities over 1200 FPS we recommend either our Heavy Plate Concave Base or Hollow Point products for superior accuracy. We recommend keeping velocities to less than 1500 FPS (Feet Per Second) and using only a light taper crimp

"Our Copper Plated Bullets can be run at mid-range jacketed velocities or higher end lead velocities. We recommend keeping velocities to less than 1500 FPS (Feet Per Second) and using only a light taper crimp"

This just proves that even the manufacturers of plated bullets have fallen into the fallacy that their product is in some way inferior to "real" jacketed bullets! Berry gives similar advice. If you peruse many loading manuals which show data for both cast lead and jacketed bullets in the same cartridge you will find that often data for the lead bullets is equal to, or slightly heavier, that for the same cartridge with jacketed bullets! And, consequently, the velocities listed for the lead bullets are often higher than for jacketed bullets of the same weight. So saying that loads should be limited to lead data becomes a farce!!!

Simply load your plated bullets, of any manufacture, to the same level you would jacketed bullets of the same weight and judge for yourself what results you obtain instead of worrying about the BS you read on the internet! It will cause no harm, and you will find that most of what is on the 'net is pure baloney. If you have accuracy issues it may be the loading, or it could be the bullets are junk. If reducing loads doesn't help they buy different bullets.

Just a word for Xtreme. The few I have purchased have been of excellent quality, and right on for diameter and weight. This is more than I can say for other brands I have purchased in the past!

I would agree with that from the ones I've gotten so far too.

The first ones I tried were the .357" 158gr-HP with the Heavy Plate Concave Base & had great quality. I recently purchased some .452" 230gr-HP, .410" 210gr-FP, & .357" 158gr-SWC. Again, dimensionally, they have great quality & consistency.

The 41 & 357 are their standard (Superior Plated Bullets) plated while the 45 is the thicker (Heavy Plate Concave Base) plated bullets. They state to use a light taper crimp which made me wonder about exactly how well the plating is bonded to them so I tried a little test, to humor myself.

Each one was subjected to (10) blows with a 4# engineers hammer on an anvil, then split with a cold chisel along it's radius. I saw no lifting or separation of the plating from the lead core due to the impacts & only minimal tearing from the chisel. While not visibly thick, like a jacketed bullet, it's bonded securely, the best I can see.

With the HPCB being rated up to 1500fps, I'd feel confident using them in the 10mm. I plan on pushing the .45 230gr HPs to see how they stand up in various guns & loads.

Awesome, thanks guys. Its always nice to see feedback from a source that isn't the company. Can't wait to get some screaming down range!

Because of all the warnings about too much crimp I actually pulled some crimped bullets just to make sure I wasn't damaging the plating. What I found out was that even a maximum Roll Crimp on their 125 grain 38 special flat points won't cause a break in the plating that is visible at 20X magnification. I've also NEVER EVER had any issues with leading with Extreme's plated bullets. It's why I ordered up 3000 of their bullets during the Thanksgiving sale.

Yea, I love their products. I've probably shot a car's weight worth of them. Just haven't tried running them in high velocity stuff yet.

Bonus, today while walking through gun stores I found another can of long shot. YAY!! 4lbs should keep me fueled for a while.

In a 40 S&W I used some 165 gn Thick plated xtreme bullets with some Winchester autocomp.
I am new at reloading but the accuracy improvement was noticeable.
I need to order another box!!! I measured up a bunch and the dia. is really consistant

+1 on the XTreme bullets (in 44 for me).
Electroplate should have as good or better a bond as the soldered and bonded big game bullets like Woodleigh.
That experiment was nice proof of that.
