After my tests of the Berry's HHP, dudedog PM'd me about could I test some RMR 124 jacketed HP's? I jumped at the chance I love to test just about anything.

Along come a SFRB that when I picked it up felt like a lot more than a few 9mm bullets. 25 RMR 124's, 5 Montana gold 124 HP, 10 Nosler 124 "sport" HP, and 10 115 Hornady XTP-HP. All got tested.

Also some .223 bullets, some Federal Fusion 62 grain BT, the fusion is supposed to be a good hunting bullet for the .223.

Well here's the first the RMR 124 HP;

Wound channel, penetration.

Pried some of the wax away from where the bullet stopped.

Classic mushroom, jacket folded back around the base. No lead or jacket lost in the wound channel. Retained weight, well if it started at 124, it GAINED 1.5 grains!

Here's the Montana gold;

That brass jacket is either too thin or too brittle. Shards all along the would channel.

Normal penetration, didn't weigh it.

now the Nosler HP;

First bullet punched through the test tube clean was lost in the backstop. Second one I put the tube with rags stuffed inside behind the test tube to catch the bullet. It too went slick and clean through, was caught in the rags. NO EXPANSION! The test tubes have a plastic cap that I use to seal the tube so the wax doesn't leak. A chunk of that plastic was jammed into the bottom of the HP. I think it is what happens to a lot of HP's, plugging is what it's called. Clothing usually causes it.

I just ordered a digital microscope, some real close ups will be on the way.

The H. XTP's were as usual, classic mushroom, some shards of lead and jacket in the wound channel.

Didn't take a pic of it, but I will once that microscope shows up from Amazon.

Nice report!

I'm pretty sure that MG bullet isn't designed to expand.

Those Nosler's are made to expand.

They show 4 velocity levels and the expansion you should expect.

I used power pistol @ the same level that gave me 1108 fps from my CZ 75. Since the CED refused to work, I don't know exactly how fast they were going.

Hmmmmmmm, I just took a better look at the picture, (enlarged), of that bullet on that box . The bullets I got from Dudedog have a much shallower HP than that one pictured on that box on the midway site! Perhaps they just HP'd them to shift the weight to the rear for better accuracy??:uhoh:
 
Excellent testing. Thanks for the test on the RMR 124 JHP especially since I picked up some. RMR got a winner there.

Any chance you can post the depth of penetration?
 
snuffy, thanks for running the test and thanks to Dudedog for sending you some bullets to test.

Can you tell me at what velocity you tested the RMR 124gr JHP's. Or if you don't know the velocity, what load did you use?

I don't think the MG's are supposed to be expanding bullets used for SD.

The Nosler bullets are really nice, but I did not know that they are supposed to be expanding.

Great report!
 
After my tests of the Berry's HHP...I love to test just about anything.....Classic mushroom, jacket folded back....I just ordered a digital microscope... but I will once that microscope shows up from Amazon.

snuffy, you are a steely-eyed testing man! We really like the pics & I appreciate your efforts to post the reports. Thanks again .....:)
 
upon further investigation;

Well 8 hours of sleep can do wonders. I was tired by the time I got those bullets cut out of the wax, pics taken, uploaded to my photo site, and the post written. Then I fat fingered the wrong place only to have the beginning of the post up and disappear,,-- oh well rant over!?

I took another look at the unfired Nosler bullets, they ARE exactly like what's pictured on the box. They simply did not expand! I see no sign of internal skiving that would weaken the ogive of the bullet.

Valpens, I intended to have velocity figures, BUT my brand new CED M-2 millennium chronograph refused to work! I just got it back from sending it in to have a problem with the sensor plugs being so loose where they plug into the base unit they would fall out just from the weight of the wires hanging from it.

Last time with the Berry's HHP I loaded them with power pistol. The load this time was 5.7 grains, max load in the Lyman manual. Last time with the Berry's HHP, that load made 1203 fps. Difference in jacketed versus plated, I would guess it's still close, lets say 1200?

Ed Jaws, penetration is relative, (and I don't mean like your brother showing up looking to borrow money),;) relative to how far it went into the test tube wax. ALL of the HP bullets went in about 4" EXCEPT the Nosler's that went straight through. Now if the bad guys all had solid homogeneous wax bodies, we could predict how far it could penetrate.

I found this U-tube video about the bullettesttube as it looked when available.

Thanks for the additional information, and thanks again for testing these bullets for us.

I load the RMR 124gr JHP's in 357sig and chrono'd my accurate load at 1259fps. Looks like my load has a little bit more velocity, so your test is a good reflection of what I can expect.

I haven't chrono'd my 9mm load using the RMR 124gr JHP's yet, but I expect around 1100fps based on my other loads.
 
snip... how far it went into the test tube wax. ALL of the HP bullets went in about 4" EXCEPT the Nosler's that went straight through. Now if the bad guys all had solid homogeneous wax bodies, we could predict how far it could penetrate.

Ahh, missed the wax part. Man I wish I had somewhere to do chrono and gel tests.

Appreciate your testing. Thank you.
 
Off topic for the RMR bullets, but I finished up last night recovering the Federal fusion bullet from it resting point in the second test tube that caught it;

That's about as good as it gets for the "little" ol' .223. Retained weight was 53.5, so it lost a bit of frontal lead during it's trip through the wax, it started at 62 gr.
 
Snuff ... You're doing some good work here !!

I have loaded and shot a few of your "test" bullets ... but I have/had no way to test the expansion ... I am working with the 357 SIG in a Glock #31 ... my dirt berm doesn't provide much info ...

I'm mostly shooting the Hornady 124 gr XPT ... more or less because they are easier to find down here in the flat woods ... and they shoot better than I can see ...

That ..223 Federal is looking good too!
 
:cool::cool::cool:
Thanks for taking the time to test for all of us!
I appreciate it.

The Nosler box I have looks just like that one. They show it as an expanding bullet but it has a small HP cavity and no skivs on the nose. Interesting that it did not expand at all.

I didn't know if the Montana Golds were designed to be an expanding bullet but the nose is skived like they want it to expand.

The RMR results look pretty darn good for a fairly inexpensive HP. I bought and loaded a bunch in case of a zombie attack. Since everybody knows zombie bodies are filled with green expansion media I should be good to go.:)
They are $116/1000, $61/500, or $36/250 shipped.

Nice results on the Federal Fusions as well. They are a pulled bullet that I got from RMR. They currently have them on the web site for $130/1000 shipped.
I imagine if you only wanted 500 and called Jake at RMR he would probably take care of you. Can't remember for sure but I think it was like $70 or $75 for 500 when I ordered them a while back.
I can't hunt with any bullets containing lead in the area of CA I am in and they don't allow any .22 cal for deer here but it looks like they might be an option for small deer where they are legal.
Looks like they will also work for zombies. :)

Snuffy also did some tests on other .223 bullets for hunting larger game than critters and posted the results for us all, here is the link for those who are interested

Thank you again for taking the time to test them all. :D
Nice to see the results.
Hopefully you can put the extras to good use.
