Some 'common' 9 Major powders are shown in this article; https://www.ssusa.org/articles/2018/1/9/how-to-use-9-major-in-a-short-barrel/

Some people who load 9 Major will limit the number of times they load their 9mm brass. But for generic 9 minor, see the answers above.

Your barrel will determine the required OAL. If it's 1.07, then it's 1.07. Try some for reliable feeding.

Accuracy might not be an issue since most 9mm .355 bullets are being shot in oversize barrels anyway. Barrel groove diameter specs for 9mm is 0.355 to 0.359, and few I've slugged were less than 0.356.

Ask Everglades.

I've had good speed with Vit 3N38 9mm data (faster than N105 results). For another powder that will work and help keep pressure low try Accurate #7.

1. I've had very good luck with the 9mm Redding competition die seating bullets straight. 2. If the rounds fit your barrel, there is no need for them to fit the case gauge. We get so many people on here trying to make the rounds fit the gauge, when it doesn't matter if they fit the gauge. It only matters if they fit the barrel. Yes, I know the arguments for using a gauge - if they fit the gauge they'll fit everything - but even that is not always true. Some people have found that they fit the gauge but not the chamber. Thus it comes down to the bottom line that the important thing is for the ammo to fit the barrel. It does not matter if they fit the gauge.

Compression is not usually an issue in handgun rounds. The data in the manual might or might not result in compressed loads. Whether it does or not is rarely a concern unless it is specifically stated as such in the manual, and it rarely is. Here's what the professionals say about compressed loads: "Hodgdon notes in its reloading data if the subject charge is a compressed load. A full case, or lightly compressed charge is an ideal condition for creating loads with the most uniform velocities and pressures, and oftentimes, producing top accuracy." http://www.hodgdonreloading.com/reloading-education/reloading-beginners/compressed-loads

Some powders are prone to producing large SDs, and Power Pistol is one of them. Yet it also produces excellent accuracy in the 9mm. There's some data at the link below using Power Pistol and 115 grain bullets. You'll have scroll down the page a ways to find the table. The article looked at consistent velocity and accuracy, and found no correlation between them in a typical handgun at typical handgun range. So, in general (with handguns at typical handgun range), you can ignore the SD and ES, and trust the target to tell you which ammo the gun likes. https://americanhandgunner.com/handguns/exclusive-consistent-velocity-accuracy/

Speer had in their older load manuals (e.g. #10) a caution to make sure that rounds had good neck tension to prevent setback in their 9mm data. They found that a load that produced 28,000 CUP went to 62,000 CUP when the bullets were seated 0.030" deeper. At the time, 35,700 CUP was the industry maximum limit. They gave no specifics on the load, bullet weight or powder used. I think the most prudent advice is be wary of pressure changes resulting from seating the bullet deeper. This will depend on how much deeper the bullet is seated and what charge weights you're loading. Adjustments can be made in charge weights to keep the pressure the same or to prevent the pressure from exceeding industry standards.

Load the bullets until they pass the plunk and rotate test and let us know what that is. What is your charge weight?

The OAL listed in manuals is not useless. It is the length they used to develop their loads, and is a guide to the maximum pressure limit they found with that bullet and powder at that OAL. It means that if you load more powder than what they used for their max load then you are producing pressure over established limits. That said, the OAL they used might not fit your gun's chamber. You might need to seat the bullet deeper, and if you do, that will raise pressure. If you're working near the max load, you'll want to reduce the charge so as not to exceed the pressure limit. How much you need to reduce the load depends on how much deeper you need to load the bullet to fit your gun. In practical terms, there is no real limit to minimum or maximum OAL. You can seat any bullet to any OAL you want as long as it fits in your magazine, feeds reliably and fits in your chamber. But, if you push the bullet deeper than the published OAL for that powder, you need to back off the powder to equal the same pressure.

The only way to know if your gun likes them is to try them in your gun.

This is an issue of logic. If the two bullets have the same weight and are made of the same material, they occupy the same volume even if they are shaped differently. If they are seated to the same COAL (and let's stay with wadcutters seated flush), they occupy the same volume in the case. Thus the remaining volume in the case is the same. People get confused about the hollow base. They think that it makes more room in the case. It doesn't. The lead that was in the hollow base, is moved to the side. That's why they have the same weight, and that's why they have the same volume, even though it shape has changed. The only way a hollow base can make more room in the case is if the lead removed from the base is not added back to the bullet. But if you do that, the bullet weighs less.

That's a little vague. Do you mean the same COAL or to the same depth? The details matter. To reiterate, if the two bullets in my photo are seated to the same COAL (with the hollow base down), let's say flush with the case mouth of a 38 Special, so at the same 1.155" COAL, the remaining internal space for the powder will be exactly the same for both.

Which are you calling the longer bullet? If both bullets are made by the same manufacturer and have the same nose shape and weight, the hollow base version bullet is longer. This picture (below) is of Berry's 148 grain wadcutter bullets. The one on the right has a hollow base and it is longer than the plain base bullet on the left. When seated to the same COAL (with the hollow base down), the space remaining inside the case (powder chamber) is the same for both bullets.

The hollow base does not provide extra volume compared to a flat base bullet with the same nose shape and weight and seated to the same COAL.

If these bullets have been pulled with a kinetic puller, that's the cause - bounce back. You'll even see it on jacketed bullets. A cushion will help reduce it, but even then it might not prevent bounce back unless you use gentle strokes just before the bullet comes out.

It might look that way, but it doesn't work that way. Recoil starts as soon as the bullet starts moving forward.

The problem with chamber gauges of any kind is that their dimensions are rarely a match for the chambers in our barrels. As you found out, just because something fits in the gauge, it does not mean it will fit in your chamber. The reverse of that happens, too. That's why we give the advise of using your chamber as the chamber gauge. It will ALWAYS be your chamber that decides what fits and what won't. Every bullet design has a slightly different nose shape and length, and each will have requirements for its own OAL to fit your chamber. Add to that the fact that different barrels have different chamber dimensions, especially the throat, and you have to make sure the bullet will fit in all of barrels/throats in which you plan to use it.

Oh, welcome to the forum!

First, the loaded rounds have to fit your barrel's chamber. Use it as your 'round gauge', not the Wilson round gauge. After all, you won't be shooting them from the Wilson round gauge. Remove the barrel and use it for the plunk test. To help determine what's wrong, see this article for troubleshooting: https://www.shootingtimes.com/editorial/reloading-tips-the-plunk-test/99389 Odds are, the bullet needs to be seated deeper - that's the most common reason for new handloads to act up in the way you describe. That's too long. what's the real OAL?

Here's the numbers when plugged into a recoil formula. (using 0 for powder weight, but any value could be used as it is simply a constant.) Gun weight values are gun with empty magazine from Glock website. G34 gun weight 25.93 oz 1024 fps recoil force = 3.16 ft lbs G17 gun weight 24.87 oz 970 fps recoil force = 2.95 ft lbs
