Btw. I do have a chrono and a labradar but didn't bring either with me. These were in my ammo locker. I mustve loaded them several years ago.I would back them down a little bit, maybe like .2 grains and see if it goes away. Clean and check the breech face on your pistol too, make sure there aren't any issues there. If you don't have a chrono and your reloading, this is a sign that it's time to get one.
If it's a well made gun rated for +p I'd probably let em fly and just back the load down .2 grains next batch, right now 200rds of 9mm is worth $120, I wouldn't pull em.Factory ammo seemed normal. I have about 200 rounds like this and i would hate to waste them. By the same token i would hate to ruin a gun. Maybe i'll see how a glock with a lone wolf barrel handles them. ETA no 2 will hit the paper in the same spot. Lol
What's the powder and OAL? I used to load 124 CMJ up (like assloads of them) with that press (the one I sold you ages ago? although you may have upgraded to something bigger better faster?) at 1.155 with like 4.2-4.3grs titegroup and landed in that same velocity range, although I dont remember primers being that effed up.I put a few of these rounds through the chrono(actually radar) today. They ranged from 1150 to 1198 fps. The bullet is 124 grain jacketed.
So i have a 650 now which i bought at least a few years ago. At that time i sold your 550. But... these were loaded with that 550. Loa is 1.148 (for no particular reason). If the markings on the container are accurate it's 5.0 of w231. Gun is a sig m17What's the powder and OAL?

Over my head but thanks. Alot to google. Trying to understand it allI do know that W231 doesn't scale well with 9mm, or at least it didn't when I used to run ladders with it.... I basically ditched that powder (well, I used it to make some .45 ACP loads, at least) when I found out I couldn't make an easy factory replication load with it without going over book. It's probably perfectly fine though if you wanted to tweak it to run a typical USPSA fluff-crew load right over minor, though.
Not even sure why i had the w231. If i use it again I suppose I will back it down a few tenthsI do know that W231 doesn't scale well with 9mm, or at least it didn't when I used to run ladders with it....

They look a little flat, which means the pressures are forcing the primer against the breechface and it's starting to flow over the chamfer of the primer pocket. This is normal for certain high pressure magnums, but not 9mm at standard pressure. The PMC case looks fine, but the Federal is looking like it's a bit hot, but that could be that Federal's case doesn't have the same exact primer pocket as the PMC does, so... yeah, this is why when we're testing out a load we want to use the same brass so we have more consistency, especially if we're trying a new handload out.Just asking, since this seems like a 'teaching moment'.
What's 'wrong' with those primers? The deep indentions? Or am I missing something?
When working up a load for any caliber i watch the primers as they will tell pressure signs. As you reach max pressure the primers will flatten out and fill the space between the primer pocket and the breech, this is a rudimentary indication that the pressure is very high. In addition to this you may see the primer start to enter the firing pin hole, that's over pressure. Its an old school method of reading pressure, some would discount it but i don't. I have a .460 rowland that the pressure was so high i would pierce the primers and powder would foul the firing pin, i modified the gun to use a 9mm firing pin which stopped that. You are at the edge from those primers. anything that i load at the edge is starline brass and CCI primers. some primers are softer than others, CCI has never let me down.Just asking, since this seems like a 'teaching moment'.

You just reminded me CCI's primers are harder because I've been using Federals for revolvers for a bit given they are softer and have been trying to work out a wadcutter .32 Long load with Titegroup. Last time I shot it it looked like high pressure, now I'll have to try again with CCI.When working up a load for any caliber i watch the primers as they will tell pressure signs.

What is the full load data on them?Btw. I do have a chrono and a labradar but didn't bring either with me. These were in my ammo locker. I mustve loaded them several years ago.
Thanks. I doubt I'll ever reload to the max, but it could help me identify issues when I start reloading.When working up a load for any caliber i watch the primers as they will tell pressure signs.
