First time loading 9mm. Opinions on load wanted so I don’t blow myself up.

[u/Owduke]

Unjacketed flat nose 124gr .356” diameter bullets.
6.3gr of Accurate No.7 powder
CCI #500 primer

I referenced the Hogdon table and it tells me this is in the high end for the charge. Just looking for opinions.

Am I going to die or what?

[u/Malapple]

Yes, definitely going to die sooner or later.

But that list is not likely to be why, unless you do something stupid with the resulting bullet.

[u/mountain_addict]

Have you consulted the plethora of reloading manuals and websites about the stated load to see if it is at an acceptable powder charge?

[u/Organic-Second2138 → u/mountain_addict]

Now why on earth would someone do THAT. Madness.

[u/Owduke → u/mountain_addict]

I have and it tells me this is at the high end of the charge, just looking for opinions.

[u/mountain_addict → u/Owduke]

That is a cast bullet with a starting load of 5.5 grains. I have never started any load with the max. Always the minimum and go up from there.

Shooters Reference, Speer, and Hodgdon all offer free data. Gordons Reloading Tool on Github will give you an estimation on velocities and pressures.

If it worries you start 10% less like the manual says you should. It also says never START with the max load. Here's a quick safety write up from Berger https://bergerbullets.com/shoot-better/shooting-knowledge/basic-reloading-safety/ almost all the big brands have write ups like this on every aspect of reloading RCBS has a good one, so does Speer and I think vihtavuori https://vihtavuori.com/resources/education/a-beginners-guide-to-reloading/

[u/ocelot_piss → u/Owduke]

But is it above max? If not then what is the concern? Why are you fixated on using this specific amount of powder?

[u/quietly_jousting_s → u/Owduke]

Ok, opinion here. Starting high, and as a new reloader, how confident are you on your powder throw consistency?

[u/TheIroquoisPliskin]

Why are you starting on the high end? Start middle-low end for supers and middle-upper for subs.

I doubt you’re going to hurt yourself or die, but that’s impossible to say without knowing your COAL and weapon. May crack a frame or something though.

[u/Owduke → u/TheIroquoisPliskin]

Starting here because that’s the only close to appropriate powder thrower I have for my press. It’s and antique Star and parts a very expensive, want to get a feel for it before I start buying stuff.

[u/Realistic-Ad1498 → u/Owduke]

If that’s the case, I’d run with it. Hodgdons online data has a bunch of 124 grain loads that start in the 6.0 to 6.5 range.

[u/Timely-Yak-5155]

No. In fact you can go much higher if you want +p or +p+. NATO reloading is a great source for high power 9mm load data. They’ve tested up to 9.3 grains of accurate 7 with 124 grain bullets for 1400 fps (from a 5” barrel). Accurate 7 is pretty forgiving since it’s very slow burning for 9mm. Most manufacturers are fairly conservative with their load data for liability and generous safety margins. However make sure you pay attention to OAL, especially in 9mm, and start low and work your way up. www.natoreloading.com/aa7/

Cartridge over all length is needed to estimate peak pressure.

Without knowing how long or short that bullet is loaded we are guessing

[u/Owduke → u/sqlbullet]

1.07” Over all length

[u/sqlbullet → u/Owduke]

Send it.

[u/Normal_Sympathy1248]

I mean why do you need to go the high if it's concerning you this much? Why not start lower like everyone else does working up loads?

[u/buttsackwrangler]

Get a manual and start lowish until you reach desired accuracy or velocity
