Hottest 10mm load

[gofastman]

I recently launched a 220gr cast bullet at 1407fps 
it came out of a 6.6" tube with a comp on it, but still, that is a SPICY meatball
I'll post details of the load once I establish that its not super dangerous

I just received my MechTech and I want to work up to this load in it!

in general, how does the mechtech handle nuclear loads?

Besides, if I want more, that I can barely handle, I pull out my .454 Casull!

yep! nothing like 38grs of W296 to wake a person up in the morning!   
If the massive shockwave doesnt do it, the front sight smacking you in the head will!

[gandog56]

I've so far managed NOT to do the head smacking thing.

[RRMan03]

I got a real world load from a friend that is 155gr Barnes at 1535fps which makes in nuclear. I will not shoot it in a Glock but in my Ruger no problems. amazing how much more the Ruger can handle than the Auto's. The cases,primers and components fail before the gun. Not so in the others.Im sure you can blow a Ruger as any gun will blow with stupidity but they will take a beating. An old gunner like me can learn if he listens and reads and listens with his mouth shut till he can ask a good question.

[445 supermag]

Why?  Because we can.  Been doing it for near 40 years, in search of maximum energy on target.  The objective: reduced package size (the very reason the Alaskan ever existed). Big power can be had, up to and including the likes of .50 BMG or .600 Nitro. The search is for the most effective power that can be reliably placed on target, in the smallest package as practical. Your comfort zone, skill level (shooting and/or cartridge engineering), and available equipment/resources are limiting factors. Settling for less than optimal (according to MY interpretation of optimal) is a personal choice, and there's nothing wrong with that. Less than 1% of all the cartridges I produce venture outside the "factory" offerings. But WOW, what a 1%!

Dm. 

I have to say when loading for my Dan Wesson 445 supermag like you stated your 1%..   for me I was easily north or 25-30% outside book. 

Otherwise I was just loading a 44 mag with a nice stiff load In a longer 445 supermag brass.

I'm trying to figure out what you are saying. You make stout .44 mag stiff loads using 445 Supermag brass? Isn't Supermag too long to fit in a .44? Or are you saying you load your Supermag brass DOWN to 44 mag specs?

[45BBH]

Maybe not the hottest ever, but dang good numbers from a stock 4.6" Glock 20.   I was using VV 3N38 and was able to average a 180gr Rem JHP at 1,350 and a 200gr Beartooth WFNGC at 1250 from my Gen4 G20.  Brass didn't look bad at all, I'm very pleased.

[Caneman]

SwampFox used to also load to these values for the 4.6" barrels...
135gr @ 1700 fps (Nosler)
155gr @ 1525 fps (XTP)
180gr @ 1400 fps (XTP)
200gr @ 1240 fps (XTP & FMJ)
200gr @ 1325 fps (XTP & FMJ) FULLY SUPPORTED AFTERMARKET BARREL ONLY

Underwood loads to these values for the 4.6" barrels...Some of these may have changed...
Nosler 135gr JHP            1600 fps
Hornady 155gr XTP    1500 fps
Hornady 165gr JHP    1400 fps
Hornady 180gr JHP    1300 fps
Hornady 200gr JHP    1250 fps
Hard Cast 220gr HCFN    1200 fps

thanks shadow for sharing this info, i personally feel comfortable with the Underwood max listed above except for the hard cast as i started to see rapidly increasing pressure at 1100 fps for my own 225gr wfn cast boolits

note:  it would be great if anyone posting load data would also post case head expansion, and the brand/age of the case, as this gives an objective data point for what type of pressure you are experiencing, to say "the primer looked good" doesn't give much meaningful information, just sayin'   

[gandog56]

Wouldn't that vary for different guns due to maybe slightly different case dimensions? Of course, their stated velocities in reloading manualsare also like that, and they DO list that.

[The_Shadow]

All of the Underwood data is listed and case expansions as tested are listed in the Pull-Down sections...
I tested the SwampFox Hornady 200XTP @ 1240 fps with good results which used LongShot powder.

[nickE10mm]

In years past I didn't limit myself to short distance shooting with handguns but challenged myself to longer shots...100 yards and even more.  I use to get great groups at 130 yards from my S&W1006 and even made a friend mad by taking his targets for his 30'06 out before he could get setup...I will say coordination, eye sight and strength were much better 23 years ago.
BTW he was shooting 30'06's I loaded for him and he was very impressed with there performance from them.

The loads were with Blue Dot...with my 44mag which took a deer at 180 yards thru the heart. 

Yes many have chased the higher velocities over the years, why?  Because the extra velocity equals extra bullet energy, less drift and less drop at distance.  It does nothing if you can hit the target!   This is where handloading my own has paid dividends, better performance ammunition, at reasonable prices, while utilizing premium components or even cast bullet for even cheaper produced ammo.  Mild to wild it's all good!

This ....

Also, I feel that the reason people choose **10mm** as their caliber to hotrod is that it's the only automatic service caliber that is close enough in power to a true hunting caliber to make it truly a worthwhile cause .... and people want to make full use of that versatility. Not only that but the 10mm has nice strong brass and is excellent for hand loading in general.

The 10mm is very versatile...bullet selection and weights across a broad spectrum of ballistic potential from semiauto package.  Not to mention barrel swaps for other cartridges like the 40S&W, 357Sig & 9x25Dillon from the same magazines to add even more flexibility!

There are a LOT of people that think 10mm IS a true hunting caliber. It's their gun of choice for hawg hunting.

Sorry it didnt come across right.   I ment unless I loaded over book for the 445 supermag I would just get stiff 44 mag load. 

See in the DW 445 supermag and using book loads it would only equal a hot 44mag or just a bit more.  You cant really get a nice bump in velocity like I would of liked to have seen

Different values. I can jump off a cliff. I don't choose to. Like I said, accuracy is all to me, and I have never achieved that at a max load in 35+ years of reloading. So personally, I see no need to do it.

[DM1906]

Then don't do it.  Simple.
