need 9mm load info

[kermit315]

Hey guys,

my lyman book doesnt list a load for 115gn, fmj, 9mm loads. I need a good plinking recipe for the above bullets with unique powder (all I have right now).

I cant find anything online that will give me a min/max charge.

Any help?

Thanks,

Jamie

By the way, What edition do you have?

[kermit315]

Lyman Reloading Handbook, 49th edition.

It has loads for HPs, but no 115grn FMJ's.

That load you referenced from alliant is for HP's also, and seems kind of high for a plinking round. Will it work well for FMJ?

From Sierra Edition 5, pg 736 :

115G FMJ
COAL = 1.100"

Unique:
Min = 4.9G (1000 FPS)
Max = 6.6G (1250 FPS)

[zfields]

Lee modern reloading list it at 5.1 grains @ 1092 FPS, 5.5 max @ 1168 fps OAL of 1.12

Yea, found it in Sierra 5th edition
Unique Powder with 115g FMJ COAL 1.100
min:4.9 at 1000fps
max:6.6 at 1250fps

cool, thanks.

what is the best (knowing that this is going to get a subjective response) reloading manual to get? The load (grains of powder) seems very close to the plinking load I use for my .45 (5.3 grains pushing 230gn projectiles). That load came from the lyman book. Lyman also has me loading my 147 grain HP 9mm's with between 3.8 and 4.2. Whats the deal with the higher loads for a lighter bullet?

You should work-up the load in your gun to see what is best for your gun. Start at the miximum charge weight, load five, then go up .2grains, load five, and so on until you reach max. When you shoot them, look at the primers and at case expansion for excessive pressure signs. Stop when you either see excessive pressure signs or the max charge weight.

Shoot off sand bags to see which charge weight gives you the best accuracy.

The correct answer is... MANY!

I started a thread a month or so ago about "which 2 reloading books should I buy?"
I think just about every possible book was mentioned by someone.

Books are relatively cheap. I've got 4 so far...
Hornady, Speer, Sierra, and Lyman.

Next time I'm shopping I'll probably get Barnes, and Nosler.

Not every book will have a recipe for the combination of powder and bullets you want to use. The more books, the better chance of finding a good recipe for your combo.
And some of the books have somewhat conflicting data, or list similar bullets but with a different COAL, which means a different charge weight. It's good to have LOTS of books to cross reference.

My answer: Get many books!

. Whats the deal with the higher loads for a lighter bullet?

1. Newton's Third Law of Motion-For every action there is an equal opposite reaction.
In semi-automatics the force of the bullet is balanced by the mass of the slide and the capabilities of the recoil spring(and any other mechanisms).
Proper loads will have the same (or in an acceptable range) force.
(A smaller bullet expelled at a faster speed than a heavier bullet at a lower speed)

2. To keep the pressure down to safe limits to keep from blowing up the firearm
(overloading) in the reverse situation. (heavy bullet with higher load)

I understand the start low and workup routine. What I am saying is, how can the different manuals all come to different conclusions using the same components (115gn projectiles, same case size, same primers, same powder, etc...) Just wondering why there is so much spread between the different manuals.

Its always a good idea to have several books on hand to get load data. I have several books I used to reference my pistol loads
