Reloading Data for Speer147grTMJ FN?

One of my Hodgdon manuals has the 147 at a maximum load of 935 fps at 32,800 psi with that powder.
Any new manual should list that powder. Good loading.

Since the Speer manual uses the same data for the TMJFN and the GDHP, Use the same Hodgdon data as for a hollow point of the same weight and you will be okay. As always, start low and work your way up to the sweet spot!

Start at 1.169" OAL for ONE ROUND and drop the catridge into the barrel after you remove the barrel from your gun. You want to hear "Plunk" -- that is why its called the plunk test. If you don't hear a plunk, reduce OAL by 0.010" to 1.159" . Keep reducing OAL until you hear plunk.
A hollow point load will have a shorter OAL because a HP bullet is usually shorter than a round nose.

"Plunk" is good.............for the 9mm.
OAL and pressures can change with different bullet shapes and even the same weights with the different company brands.
It is all due mainly to the bullets tip's shape called "Ogive"
Bullets set too deep in a case can cause dangerous pressures....
A long OAL of around 1.69 may give better accuracy along with lower pressures.
However you may have the bullet hitting the rifling if too long of an OAL for the bullets design, which will also cause very high pressures.
All loads for automatic pistols have to meet a lot of standards to be safe with the powders used with the different burn rate and case volume that they take up along with the base of the bullet also inside the case.
Like an old carpenter once told me..........
"Measure twice and cut one time."
Stay safe.

You typed that one backwards. A HP projectile will be longer than a RN projectile of the same weight from the same manufacturer
Remember the HP has a big hole in it that weighs nothing so that hole has to be made up for in extra length

That is what always bugged me.............
I see a JHP set at 1.09" and a FMJ set at 1.12" oal. (Hogdon)
Then another manual calls for the JHP at 1.125" oal. ( Alliant )
What I hate even more is one load in PSI and the next powder in CUP !!
Now how the heck am I going to compare the two powders for pressure against one another?? (Hodgdon)
OK, rant over.
Per post #9
Now that you loaded them at 1.169 and all was ok..........
One 147gr factory load has a OAL of 1.13". Probably so it will work in most guns and maybe
to also save a little powder? Good luck with those loads.

This may seem strange but it is actually true!.
Speer actually prints a manual that has the load data in it!. For the few dollars it costs, there is lots of information in it.
No, you should not just the same OAL as a RB bullet as they are nowhere the same.
Speer actually uses a start of 3.6 and a MAX of 4.1 which is what you are starting out?
Just for safety sake, the COAL they use is 1.130. (same as the GDHP)
Manuals are your source of wisdom and enlightenment.

I reloaded from the winchester data....there was nt much of a difference between fmj and jhp in the charges and pressures...both loads cols were 1.169 4.o grs to 4.3 max.....it shows no 1.130 in any of the loads for this bullet....Rusty
If you do not want to use the data published by the folks that make the bullet (Speer #14,) than that is up to you.
What is Winchester data? From Hodgdons? What bullet is that data for? It does not list the make or shape. There is data for a a Hornady XTP but not YOUR bullet. The data from Speer is YOUR bullet. A flat nose is not the same as a JHP or whatever Hodgdon used. You can use the weight of similar bullets but COAL is a whole different thing,

Go here for load data for the 147 using WSF: http://data.hodgdon.com/main_menu.asp
I just finished loading the same thing myself.

I went to Hodgons data..went to JHP and got the data...the fmj is very similar also...if i'm wrong and i have to tear the 25 i loaded i will..just want to make them correct....someone tell me i'm wrong if i am....147 gr tmj fn..i'm told that what speer calls their fmj bullets...am i wrong??
I already mentioned what Speer data says for their bullet. Do not know how else I can explain it?? Does the Hodgdon data say FN?? No it doesn't.
The powder charge will be lower as they seated the bullet deeper (or the bullet is just shorter than some other bullets) the weight of the bullet has to go somewhere so it's usually in the base,
It's not often we have the exact bullet that is tested. If you had Hornady XTP the Hodgdon data has that as does the Hornady manual.
If you were seating it shorter rather than longer then you would end up with more of pressure situation but as it;s longer it will be more of a feeding properly or not.
Buy the manual and see for yourself, it's good to have as many as you can.
The main reason for OAL................
is to control the amount of the bullet that is seated "INTO" the case......................
which sets the amount of space between the bullet and the powder charge.
"Air space" or the lack of it, has a lot to do with the pressure of the load. Some types of powders can "NOT" be compressed due to the higher pressure that come about.........
while other types do well being compressed, to achieve safe maximum velocity.
Many of the reloader's that have many years of loading or have read a lot on the subject, have picked up on these facts and understand the what and why of things and all the parts that go together in developing a safe load.

I gave you the correct data
Not unless you loaded up more than 4.1 grs then you have no real problem other than your COL of 1.169 is a little to long. If the cycle through you gun than OK fine. Better to be to long than to short as far as pressure build up.
It is better to start at the low end of the data and work up. Not use the max load to start.
If you are absolutely positive of you powder load, then see if they cycle and shoot them. If it is more than 4.1gr then take them apart..
You will find that test data varies a lot from manual to manual and online data web sites. In this case you have a known bullet and a manual that gives how Speer tested it. That's as good as it gets.

Thankyou once again...4.1 is dead on...i saved 5 from the loading and i got some good data tonight...with that bullet min is 3.6 to 4.1 so i was at max...it tell shows 1.169 for the oal....and it did cycle threw my mp...so i'm happy and i finally got very good data...thanks for putting up with me...I've only been reloading for a year...and i'm a rifle shooter and reloader...Iwas honestly listening to you guys the whole time..just wanted to get the correct loads to be safe...thanks again. Rusty..
