I'm looking for a good starting point for a 9mm load. Just started shooting IDPA and zombie matches (idpa with zombies :cool: ).

This is through a Glock34. Im planning to use precision delta fmj bullets.

Also, will be using Bullseye (I have 16 pounds of it, so I really need to use this up :wow: ).

So, knowing those parameters, Id be interested in some suggestions on which bullet and even a load recipe if you have a bvullseye favorite!

I never thought Id ever reload 9mm, assuming the price difference wasn't great enough, but given the volume and the retail price- Ive changed my mind!

Just get a 124gr RN bullet and load it to 1100fps using 1.130 OAL

:agree: 124g PD FMJ's are my choice for Glocks.

Thanks C4W,

Maybe I'm over-thinking this :-)

Alliant is pretty stingy with load data, so I'm planning to work up the load with my chrony, but first I need to pick the bullet.

I guess there's not a helluva big difference between 115g and 124g, I was just looking for some feedback before I order 2000 of them :-). Most the commercial stuff I see is a 115g bullet, so that was my initial instinct, but so many folks seem to use heavier bullets....

Actually, the 9mm was built around the 124 grain bullet.

Ha! Your right (of course).

I was thinking more of the most typical commercial stuff I see (as opposed to NATO). I guess its just as likely the commercial stuff is 115g because its fractionally cheaper, rather than more reliable.

I like Bullseye in my Glock 17 with the 124 gr fmj at 1.150 OAL. I have loaded it anywhere from 3.6-4.0 grains. 4.0 Grains is 135+ power factor, extremely accurate (FC BRASS and CCI PRIMER).

Actually, huge difference in terms that you can load subsonic and still have a load that runs reliably in your platform. As C4W pointed out try and stay at the 1100 fps mark, especially with stock springs. I prefer and use a 11-13# ISMI in my G34 as I like the sight tracking with the faster slide velocity.

It's easier to get the min PF using a heavier bullet. BE would never be my 1st choice, but anything goes bang in most handgun calibers. You need 1050fps w/ the 124gr, work upto 4.3gr. You need about 1120fps w/ the 115gr, about 4.5gr. As you can see, both are pushing hard & you are barely getting to a true min PF. If I were running 9mm in IDPA, I would be looking a the 147gr bullets @ 875fps, easily done w/ just about any powder.

My favorite bullet weight in 9mm is 130-135gr. I made some of them and the way they tracked with the sight was awesome. Least favorite is 115gr. I would use the 124gr and not even consider anything else for right now. THEN try the others after you have a feel for the 124 gr. You want to load to 1100fps for a variety of reasons. But not cheating is a part of it. I guess Zombies don't care but IDPA does. 1100fps just works pretty nicely as well. It is just a 9mm after all. Might as well have some umpf behind it for knocking down steel, etc.

I know :-)

I bought several kegs of it from a guy that was getting out of reloading.... I think I got 32 pounds of it for like $100.... hard to pass up on that.

Since Im not loading as much 45acp as before, Itd last me 1000 years if I dont use it for 9mm :supergrin:

Do not over think it, over analyze it, or make it more difficult than it is. Pick out a good bullet, a good powder, load to a 135 PF.......shoot the hell out of them.

Finding the perfect load is not going to turn a marksman or sharpshooter in IDPA into an expert or master shooter. Loading and shooting 100,000-200,000 rounds can.

keep it simple, don't over think it.....load and shoot as much as you can.
16# of BE is almost 25,000 rounds. BE is an old powder. It has many uses. BE does a lot of things, just not a lot of things GREAT. If you can't sell your BE or trade it, do not waste it just because it is not popular on this forum.....it is still a good powder.

My IDPA load is a 125gr LCN over 3.9gr BE. Runs 1040-1060fps out of my P226. While a different gun and bullet, just letting you know that there are plenty of us that still use BE.

I will admit that I'm testing Unique, WSF and WST for a possible changeover.

Seriously. Last match one of the guys was shooting 9mm, pretty soft loads, probably not 125PF, we had to shoot two poppers while moving laterally to cover, he must have hit each one 5X before they dropped. All I could say was "Bill, bigger bullets"!.:rofl: BTW, no issues w/ a 200gr bullet @ 840fps, one round each.:supergrin:

Yep, set the popper too far forward.... and you've just identified another means of discretely trying to eliminate the competition. :tongueout:

A 125gr 9mm at regulation PF will knock down a popper, unless they're being struck like you were playing crockett at 6" off the ground.

That being said, 200gr at 840fps leaves no doubt if you hit the steel.

Well, I know these guys are shooting less than 125PF at some of the local matches. Winning to some is everything. I can't imagine it helps your shooting when you have to go shoot a sanctioned match w/ real ammo!:tongueout: I have also seen my share of limp wrist jambs from sim loaded ammo. Usually weak hand shots.:dunno:

147 gr - Delta Precision - 3.2 gr Titegroup - 1.135" OAL = ~132,000 pf
