Load data for Rocky Mountain Reloading 115 Gr FMJ

[DarkKing]

Anyone have recommended load data for the RMR 115Grain FMJ

http://rmrbullets.com/shop/bullets-for-reloading/9mm-115-grain-rmr-fmj/?v=d55431c73d2c

I have been browsing and can't find anything.
(I have already sent them a contact email using their form and waiting for their formal response.)

It also seems this is a newer round and not in a load manual from what i can tell.

I am not sure if i should use

http://www.handloads.com/loaddata/default.asp?Caliber=9%20mm&Weight=All

115gr FMJ 5.0 gr Bullseye 1,180 fps 1.12" WSP Alliant
Suggested starting load: 4.5 gr
Pressure: 31,000

I just cant find anything for their bullets. I bought 250 of them because free shipping on 250 for 30$'s can't really be beat.

A 115 grn FMJ, is a 115 grn FMJ. Doesn't matter who made it. Load data published for one is same, same as other manufacturers.

There is always slight variations in published date from different sources. But that is not due to the name on the box of bullets. It is due to variations in testing equipment, powder lot variations, chamber size of test gun, and a butt load of other items. Which even includes the temperature and humidity.

Those variations in data are irrelevant. It is incumbent on the reloader to do "due diligence" and start well below any maximum load and work up in small increments to a safe level that meets his own requirements for the load.

Where that does get a bit sticky is to not use Lead core jacketed bullet data, when loading All Copper buzzard proof ammo in a rifle. Without data from the "maker" saying it is OK to do so. Same weight of those is "longer" than lead core. Giving more bearing surface in bore, which increases pressure.

I guess my biggest worry is COL as i know if its to long it can get stuck if its to short it can blow.

I am seeing some people say 4.6 Gr and a COL of 1.135 and then 4.6-5.0 with a COL of 1.125 lol.

I am seeing some variation lol.

my loading manual only has JHP for 115gr lol so it lists a far lower COL and powder charges as well.

[DarkKing]

After reading a lot and using my lynmann manual and handloads website and other posts I am thinking.

115GR FMJ with COL/OAL at 1.12 with bullseye @4.6 gr.

I will be using a Glock 19 with this ammo and I am thinking of a 9mm carbine/rifle later on as well due to the ease of reloading the 9mm.

Just don't start at the max load and plunk test to verify COAL isnt too long

Max recommended is 5.0 GR with bullseye according to the handloads chart.
and others list at 5.1 so I will stay away from that one.

they recommended we start at 4.5 so I am going to do 4.6 gr(its what the lee pro has)

I own a David Sams custom Beretta M92 built for Bullseye Pistol. Mr Sams recommended pushing the bullets between 1150 and 1200 fps with Power Pistol. I conducted load testing with RMR plated and various other bullets and with Titegroup. My data is as follows:

I will be using a Glock 19 with this ammo and I am thinking of a 9mm carbine/rifle later on as well due to the ease of reloading the 9mm.

Last week I loaded XTreme 115gr RN pills with 4.6gr of W231, COL 1.125, and ran them through my Glock 43 and 9mm carbine yesterday. They both ran like tops, had no failures to feed or eject, and accuracy was good (for plinking steel at 25,35,45yds). I also loaded the same round with 3.5gr of W231 and the Glock wouldn't cycle reliably. The carbine, however, was smooooooth like a sewing machine and very quiet.

Different powder, I know. Just sharing my experience.

Mike above has good advice.

Far to many Noobs spend far to much time head scratching and stressing over COAL.

If it fits and cycles through your magazine. And fits and cycles through you pistol. It is GTG.

Choot em.............just verify fits/cycles first.

Enjoy

That's not entirely true. If you press the projectile too deep you'll increase the pressure upon firing. Depending on your load this could be bad news. Im thinking near max-max loads would be the. Kat. Abuse for concern.

For rounds with cannelure I don't even measure the oal any longer.

Anyone have recommended load data for the RMR 115Grain FMJ

...

I've loaded and chrono'd a bunch of the RMR 115 FMJ.

I had to load them at 1.120 in order to plunk in my CZ. With a glock, I wouldn't worry too much about OAL, you could probably go as long as 1.150 with no issues. But as always, you should do the plunk test and find out what the limit is for your gun.

Is bullseye the only powder you have?

YES but I can get titewad, universal locally but that is it. Other than that I have to have it shipped and I can only get a few things shipped to STORE for basspro which is a 30 min drive away.


I can get universal from turners locally and titewad from a local gunshop.
