9mm 115 gr and unique

I just went down and bought reloading supplies for the first time and I thought I was buying 115 gr jacketed bullets but they ended up being copper plated so my loading reference isn't valid anymore.
My loading reference said to use 5.1 to 5.5 gr of unique for the 115 gr Jacketed bullets but I ended up getting plated bullets so is it safe to follow the next heavier lead bullet reference for unique at 5.3 to 5.5 gr of powder for 125 gr lead bullets?

6grs is safe with 125gr bullets @1.125 OAL, so YES go right ahead with your plans.

BTW, these are plated bullets. The same ones I use. And I use their tables.

According to the chart, 5.3 grains Unique is max for the 115 grain plated bullet.

Load plated bullets the same as lead, or reduce jacketed loads by 10%. My Lee manual has lots of plated specs.

5.3 grains with a 115 won't cycle most pistols.

oh yeah?

Prove it

Hornady says as low as 4.7g

Nosler says as low as 5.1g

Sierra says as low as 5.0g

RCBS says as low as 5.2g

Hercules said as low as 5.0g; Alliant says 5.5g MAXIMUM

Speer says (in #13) as low as 5.6g

Lyman says as low as 4.5g for lead, 4.4g for jacketed


Perhaps fewer blanket statements, or more knowledge, or something, ay?

I've tried it.

Speer says 6.3 grains is max. 5.3 sounds like mousefart in my experience. Best accuracy occurrs near the top end.

Have you tried it that low? Did it lock the slide on the last shot? Did it shoot clean, or did it leave alot of unburned powder and soot? Maybe you you should try some hands-on experience before releasing your theories?

Thoese numbers are not his theory , they are facts from the company.And tell us oh wise one what weaight was the slide vs. the spring ect ect because my ruger p85 spit out my first reloads on my lee pro.They where 125 grain lead with the .57 auto disk thinking it was 5.1-2 grains of unique.Then I got my scale and that came out to a CONSISTANT 4.7 grains, I would zero the scale then use a check weight that came with the old redding i got but I was worried they where off. It would zero and even weigh every check weight I had exactly , so that and the rounds only flying out a foot and almost falling out of the slide "lol" and everyone here telling me that was common for safety made me beleave that NOS scale was right.There is my proof , 125 Gr. LRN ,4.7 Grains of unique,1.150 OAL,Factory New Ruger recoil spring , idk what pound it was ,cant remember,and still shot and locked back.That's what i know.LOL

Diplomat, that's the load I use for IDPA. 124g (Rem JHPs though) pushed by 4.7g Unique. Dang accurate in the Hi-Powers and CZ75. My auto disk is setting is .57. Should tell you something about the LEE ADPM. Good stuff huh....

I'm shootin eurotrash pistols, so that may be the problem. I guess they're set-up for +P+ level stuff.

Still, you don't want to use Unique for low velocity applications. It will burn dirty, have a large ES, and won't be accurate.

Donkey,

What is dang accurate?

According to the MidWay Load MAP for 9mm, 5.4 gr of Unique under a 115gr "Midway" plated bullet still gave less than 30,000 psi. (35,000 psi is SAMMI maximum). They called this a compressed load. However, the OAL of this load was 1.165", quite long for this type of bullet.

Be careful not to make your 9mm loads too short or pressure may unexpectedly increase.

My loads for 9mm & Unique with Berry Bullets (plated) is 5.2 & 5.4 gr. with both the 115 & 124 bullet. 1.13 to 1.15 OAL in a CZ75B, PCR, & CZ75(PreB) with extra-power recoil springs.

As of this writing, very little soot, no failures to cycle, and accuracy on par with my other loads.

Maybe it's because I'm using that "new improved" Unique......
