10mm

[RobertTaylor]

Anyone load 10mm? Any good suggestions for some real heavy loads?

 

[Bowhntr6pt]

I started last year. I'm getting good results with AA #9 powder and Hornady 180gr XTP's.

13.6grs. is getting me 1290 FPS from a G40.

Kills hogs effectively as well as deer so I've not tried any other load development other than the 155gr XTP which was running around 1450 FPS.

This guy, and others, dropped in their tracks...

I've loaded 10mm since the late 80s, but I don't give out my personal load data. You can find load data for most powders online, but today's published loads are pretty watered down from the early ones. If you can find an early load manual, it'll have loads more up to the potential of the 10mm. But like any load data, proceed with extreme caution.

+1 for AA #9, and I also like Blue Dot.

The heaviest 10 MM bullets I've seen are 220 gn. When you go above 200 gn. I think you are really limiting your powder options

Looking for the hotter stuff. Everything recent definitely seems to produce pretty low velocity

Use a good dependable chrony and just work up from published loads... that's what I did, when I got close, I stopped.

What pistol are you using?

That's kind of what I noticed when I started looking into 10mm data.

I'm by no means an experienced 10mm loader, but I felt the 180gr was a nice compromise between weight and speed.

I'm not sure if going above 180gr would benefit me any...

Only have a rock island 1911 for now. Wanting to get something nicer at some point. No issues with it though.

I wanted to go Blue Dot but unfortunately could not find any. Have PLENTY of AA #9 that works GREAT in .300 BO sub-loads so I gave it a try, glad I did.

Been looking at those, would like a 1911 style 10mm.

Think a 1995 sierra handgun manual might be old enough?

 

[Bowhntr6pt]

I have some copied pages from Sierra, looks weak.

Don't know if this helps, but it's what I used when considering my load development.

I'm by no means an expert. Ymmv.
AA#9 12.5g 200 gr gold dot hp. I don't have a chronograph. So no speed info.
Accurate @ 100. Deadly from my carbine. DRT never took a step. +/- 50 yards. Back side of deer had a hole I could stick my flat hand in up to my thumb. Wouldn't think twice about grabbing it and going deer hunting again. ( under 100 yards) want to take a deer with my G20.

I don't get or give "recipes" for loads but if you need more punch than Alliant #9 published data, you need a .454

Wasn't needing more, just had noticed a lot of the stuff in my few manuals seem pretty low, considering what underwood ammo is putting out, that's supposedly safe for all 10mm handguns.

Nope, the AA9 data gives you 200 grainers at around 1200 fps. That's LOW to you?

My manual doesn't show that. Older sierra manual I borrowed to read through has a 190 grain hitting 1050 max. Got one from hornady showing 1100 max for 200 grain. Don't really NEED any more, just curious at this point as to what it can REALLY do without damaging anything.

 

[Rebel_Rider1969]

I've got these, have to figure out a load for them at some point. 125gr frangible. Some for roadrunners too. Lipstick for a pig hardcast.

I’m waiting on a box of 180 grain fn tmj pull downs I’ll be working a load up for. Finding powder that meters decent, and finding it in stock are now my problem.
