I found some 9mm bullets but they are 145 gr and I only have Ram Zip for powder. My manuals and what I have found online give load data for Ram Zip with 147 grain bullets, but no data for 145 grain. I have found data for 145gr but not for use with Ram Zip powder.

I am loading for training only, and do not need precision accuracy or any particular velocity so I think I should be safe going with a mid level load for 147 gr bullets. I would appreciate any advice on this. I am only concerned with safety at this point, not performance.

Thanks.

You can safely use the load date using Ram Shot and 147 gr for your 145 gr bullets.

Thank you Trooperdan.

Rule of thumb, as long as the bullets are of the same basic construction and style - i.e. both FMJ or both cast lead RN or both plated RN, etc. - a given powder charge is virtually always safe to use with the next lighter weight bullet. You can use the powder charge for a 147gr bullet for anything down to a 124gr. You can use the powder charge listed for a 124gr bullet for anything down to a 115gr. You can use the powder charge listed for a 115gr bullet for anything down to a 100gr, etc,
So your charge for a 147gr is perfectly safe with a 145gr - as long as the bullets are otherwise basically the same - both FMj, both cast RN, both plated RN etc.

Rule #1 with a 145-147 gr. bullet in a 9mm pistol is to get the OAL correct
for the amount of powder that you are using.

This long bullet can take up a lot of space in the little 9mm case and build up pressures in a hurry if you try to "Hot Rod" loads.

In my 3.5" C9 pistol a FMJ 147 with fast to slow powders will do
807 to 975 fps, with the Speer TMJ.

In my 5" barrel a 1.165" OAL load of red Dot will do 848 fps
and a OAL of 1.13" with BE-86 will do 1220 fps, with the Berry plated RN. (edit: 1220 should read 1040fps ) sorry.

850-890 seems to be a sweet spot for a nice target load.
Have fun.

"...and a OAL of 1.13" with BE-86 will do 1220 fps , with the Berry plated RN."

There is only one load in Hodgdons (for "any powder") using a 147gr bullet with a MAX velocity above 1K (and THAT'S just barely: @ 1004!)... Ed, that 1200+ seems (at least to me) to be really high?

Jus' askin'...?

Cheers!

P.S. And that doesn't appear to be a TP (thick plate) version, either.

You are correct...........

that 147 fps of 1220 was for a 124gr,
the 147 gr bullet with BE-86 does 1040 fps.

I was looking at the wrong line of my data notes.
Thank you for the heads up.

PS;
but we all know that data might be watered down from the ammo of Yor
and older ammo was a little stouter than today's .

I betya that I could probably get another 180fps out of that bullet if I tried but I'm not into shooting "Major loads" in my pistols.

PS;
still wrong info....

I will get it right and be back.

Discretion being the better part of valor... Nor am I! That's way into so-called "9mm +P+" territory!

P.S. Not even CLOSE!

Long story short...........

That 1372fps Major loads fps is for a 124 gr bullet.

The 147 gr bullet in a Major load does 1175 fps with a PF of 172 Max.
1130 fps with a PF of 163 is the starting Major load.

Buffalo Bore does load a 147 gr. bullet to 1175 fps if you have a weapon that will shoot this +P+ ammo, safely.

Geeeezzzze.

I need a cup of coffee.
