I will be starting to load 9 mm 115 gr. Missouri Bullet LRN with Unique powder soon. What is the a good manual that gives starting and max load with OAL. I have Lyman Manual and Alliant Reloader Handbook. Neigher of those have what I am looking for. I read an older Lee manual gives a starting and max load of 5 gr. I do not mind buying a manual that has the data I need, I just do not want to pay $20- $35 and then not have what I need. Considering Speer, Hornaday, Lee Second Edition, etc. Any recommendations?

Lyman 49th will have that data. 90% of the time, it is where I find what I am looking for.

I do not see anything there on 9 mm 115 gr. LRN. They do show 90 and 120 gr. (# 2 Alloy) on page 342. That is the closet I can find in the Lyman 49th. Surprised there is nothing specifics to 115 gr. LRN for as common as they are.

I've loaded that same bullet with unique. I used the lyman 49th 120gr lrn data.
I settled on
Wsp primer
Mil once fired brass
Mbc 115 gr lrn
4.8 gr unique
1.065 OAL

They were some pretty good plinkers. I had to seat those deep bc the throat on my pf9 is small. That was the OAL in the lyman manual anyway.

Based on the 90 and 120 gr. data a starting load of 4.4 to 4.5 gr. may be a safe place to start. I will see what the RBCS book tells me and go from there. I should have my dies by the weekend. Will make up some dummy rounds to determine the OAL for my gun. Thanks for your input!

Use the 120 Gr data. Yes, one would think they would have 115 Gr data. I guess with the #2 alloy they come out more like 120.
 
My RCBS Cast Bullet Manual number 1 shows 5.2 to 5.7 Grs Unique with a 115 Gr RN for 1127 to 1244 FPS. It doesn't list the OAL.
 
First off, I was pretty surprised when I got home and looked this up that there is no unique load data for a 115 grain lrn... I still stand by lyman being a good choice:)

One thing you will find pretty quick however is that you do have to extrapolate to some extent on many loads. As already stated, using the data for the 120 grain #2 alloy would be where I would start.

Your OAL very well may not be even close to the 1.065 listed but what really counts is whether it works in your gun. If you do a search for "plunk test" you will find several threads that walk you through finding the correct OAL for FUNCTION in your gun. It took me more than a year to take this seriously so I can't stress this enough. Find the OAL that passes the plunk test in your gun and go from there.

At that point, I always start at the minimum listed load and work up in .2 grain increments until I find accuracy. Watch for pressure signs as you work up and you won't have any worries about kabooms.

I was surprised too the Lyman Manual had no data for the 115 gr. Based on what I see on the 90 and 120 gr. data I will probably start with the 120 gr. data and work up. Confusing part is the RCBS data mentioned which I need to verify and take into consideration.

I will definitely make up dummy rounds to get my dies set and determine OAL verified by the for plunk test as that is gun specific. I have three 45 cal 1911's and each is slightly different. Ideal OAL on those vary .025" from longest to shortest.

Thanks for your input.
 
I checked several years worth of Alliant load data (2012, 2013 & 2014)
& they did NOT list any for 115 gr lead.

I think that may be a hint that Unique isn't the best for that particular bullet.

Good advise for well-seasoned (old) reloaders.
If you are new to reloading - just don't!!!!!
 
If you are going to load cast bullets the Lyman 49th Edition manual is good but the Lyman Cast Bullet Handbook 4th Edition is even better. It isn't just a reprint of the lead bullet data in the Lyman 49th edition, it adds a lot of extra data and from molds other than those made by Lyman.

The 9mm data from the 4th Edition lists a charge range of 4.0gr to 5.0gr Unique under a 120gr LRN bullet for 1013 fps to 1194 fps.

I forgot to put lee in that gallery, so I'm attaching the pertinent pages from lee's book. you can also check the bullet and powder websites for powder info.

You can use 120 or 125 grain data, and you can probably also use 115 grn jacketed data. just start with starting loads and don't work up too terribly high.
