147gr 9mm new loading questions

If someone could dust off their formula for 147gr lead flat point with Bullseye, I'd appreciate it. Lyman manual has 2.8-3.5gr and OAL of 1.058".

We were trying to do 9mm for first time, have all set up on Dillon 650 and have a few done, but they:
1. look very short for oal - 1.05"
2. were not chambering in any of our guns, glock 17, and some other 9mm.

What is max. oal?
Does having such a short bullet increase the pressure a lot?

Would like to know thoughts as this is our first 9mm in a while.

I seat mine to 1.15 with Missouri Bullet Co 147 gr because that's what works in MY gun. The load info came from Ben Ammonette at Alliant,
9mm Luger

115 gr lead bullet
Bullseye start 4 grs max 4.5 grs
Unique start 4.5 max 5 grs
Power Pistol start 5 grs max 5.5 grs

115 gr jacketed bullet
Bullseye start 4 grs max 4.5 grs
Unique start 4.5 grs max 5.5 grs
Power Pistol start 5.9 grs max 6.3 grs

124/125 gr lead
Bullseye start 3.8 grs max 4.3 grs
Unique start 4 grs max 4.5 grs
Power Pistol start 4.8 grs max 5.3 grs

124/125 gr jacketed
Bullseye start 3.9 grs max 4.3 grs
Unique start 4.5 grs max 5 grs
Power Pistol start 5 grs max 5.5 grs

147 gr lead
Bullseye start 2.8 grs max 3.3 grs
Unique start 3.2 grs max 3.6 grs
Power Pistol start 4 grs max 4.5 grs

147 gr jacketed
Unique start 4 grs max 4.5 grs
Power Pistol start 4.5 grs max 5 grs

Note: Start with the minimum charge wt. Reload just a few and be sure they will properly cycle the action of your pistol before reloading a quantity.

Book oal means nothing. Use an oal that functions in your gun.

Unless you use the exact setup from the book, their oal is meaningless.

We have a winner!
I wish more people would realize this.
COAL seems to be one of the things that give most new and some not so new reloaders a hard time.

The proper COAL is one that works in the gun being loaded for.

Like many others I learned the OAL lesson the hard way.

When I first started loading for my 1911, I had no Calipers so I eyeballed a factory round in my mag and seated to mag depth. No problem.

Thanks all.

Yes, oldreloader - 147 gr lead
Bullseye start 2.8 grs max 3.3 grs (2.9 at moment for start)

that is what we are doing but were following the o.a.l stated in the manual and it just looks wrong and does not cycle.

I'll adjust the seating die and put up to 1.1 or so now that everyone is saying to put it where it works on your gun.

It loaded fine in glock but jammed up so bad in eject that we had to really pull on the slide to get unstuck. Not fun with a live round in there! I'll test on different gun as the glock is too new (50 rnds only).

Anyway, will try next weekend and extend the oal and then try to shoot a few off to see how they are doing. I want to load +1,000 rounds on first large batch and want to make sure the bullets are going to work.

It has taken months to get all the right parts and switched over from .45. Just cause only working on it with my Dad every other weekend so not Dillon's fault.

One quick question about the Dillon, the clear case tube for 9mm is same size as .45. They sent a new one and just wondering if that is correct. It works but I thought the tube would be narrower.
