Back off a little, say 10%.

Yes you can use them. Start with suggested start load and work back up.

"Working back up" serves little purpose. Pressure signs are meaningless in straight walled pistol cartridges. The only way to know what pressures you're running is to abide published loading data. Which includes primer selection.

^^^^ What he said, especially regarding the AA7.

What is wrong with TG in a 10mm? Assuming you are not trying to hotrod it to max 10mm velocities, and using it within its intended window, it shouldn't be any different than using TG in a .40.
If you are already at a starting load I wouldn't worry about substituting the magnum primers.

Are you saying that working up straight walled pistol rounds is a waist of time? Are you saying it is safe to start right at the max load? Are you saying published load data is a recipe and must be followed to the letter? Are you saying that the pressures listed in the manuals will hold true in every firearm? For example, if the manual lists a pressure of 30K psi with a specific load, would that 30K psi hold true in every firearm the load is fired in?

During the obama scare, the only primers I could find were Fed SP magnum.
so I used them in all of my handguns that took small primers.
As long as you're NOT at max charge, they're just fine.
_ Good question, though!
Stay safe my friends.

I'm telling you that pressure signs in straight walled pistol cartridges is an indication of nothing. I'm saying that you can be well below industry maximums and see so-called pressure signs. I'm saying that you can be well over industry maximums and see no pressure signs right up until the gun blows up. I'm saying trust your data and check it with a chronograph.

Well a lot of guys say NO to titegroup in 40 as well

Since your charge weight is already at the recommended starting charge weight using a magnum primer with that amount of powder will probably help the load.
BUT, I would not use that powder in the 10mm either. If you like Hodgdon powders give Longshot a try. It's a great powder for the 10mm and 40 S&W.

Published data is not an absolute. Variations between firearms cause variations in pressure. That's why we have a safety margin, to cover those small variations in pressure. As long as your chamber is within spec then pressures will be within acceptable range.
Thanks for the information.
I have to admit, I'm sketched out on using TG now Should I disassemble my other rounds with regular primers? Ive shot about 55 rounds with this recipe, but id rather not have a kaboom and not be covered with the warranty with my pre ban glock?

As long as your load is within published data, just shoot them up.
Don't want to sound cavalier, but KB risk on the internet is way overblown. If you are near the starting load, and have the correct bullet seated remotely correctly, and didn't double charge them, you are fine. Fire away.

yes you can use them. i have use mag primers in 9mm and 40 s&w. i did not back off any and the mag primers gave me about 50 fps more over the standard primers when i check them across my chronograph. now i don't run my load at the top end, so 50 fps was no big deal.

Are you a lawyer??? No, the statement is true, within proper context. Obviously, the only way to know exactly what pressures your load is generating would be to have pressure testing equipment. Even then the data will only be true for that set of individual circumstances on that day. Shoot another 500rds and build a little carbon in the chamber and pressures might jump 1000psi (that's just an example, lawyer) the next day. Adjust your dies and pressure may change another few hundred PSI. So no, you never truly know exactly what pressures you're running but as long as your firearm is within spec and you follow your data (checked with a chronograph) then you can be fairly certain you are operating at safe pressures. Like I said, you can see so-called pressure signs and be below safe maximums or see no pressure signs right before the gun blows up. Too unreliable.
The point is to trust and follow your data, not so-called pressure signs. Now if you want to create an argument over semantics you'll have to find somebody else to play with.

Not semantics, poor and potentially dangerous advice.
Telling a fellow handloader that "working back up" is a waist of time. Pressure signs are "meaningless". Following published load data can predict pressures. All Bad advice. Semantics, I think not, bad dangerous advice, period.

Then I guess you're a smarter guy than John Linebaugh??? I guess he didn't really test guns to destruction and see no pressures signs right up until they blew???
It's bad advice to advise a fellow handloader NOT to deviate from published data? It's bad advice to advise that you may be over safe pressures and see no signs? It's bad advice to advise to always check your data with a chronograph?
Maybe you should try having a two way discussion instead of asking loaded questions??? You could've asked me the source of that information. Yet you chose to play games and ask loaded questions.
PS, It's waste, not waist. If you're gonna go out of your way to insult someone, at least spell it right.
