Just curious from all the home made test done what y'all think is the most devastating round tested.  Not so much the penetrating depth. 10mm of course. 

It would be very hard to deny several different rounds and some are not sold in the 10mm cartridge.

Federal HST 180 @ 1300 fps would be a very devastating round, non factory (handloaded) but these are not offered as components.

Any Gold Dot bullet should live up to performance...

The Buffalo Bore 155 TAC-XP @ 1450 is available as commercial cartridges.  They are costly because they are 100% copper.  Barnes TAC-XP line has 125, 140 and 155 grain bullets in there line up as components.

Winchester SilverTips also expensive.  If Winchester would load their Ranger and Ranger T series to some higher performance, they would be good to go, but these are not offered as components.

Most all of Underwood's 10mm offerings are quite capable of most any task.

Handloading does offer many options to dial in a performance level for your needs.

135 Nosler from Underwood or Double Tap.

Most can mean many things I guess. Some like fragments, penetration, expansion, etc... I have seen the 155gr Gold Dot expand like crazy and hit hard!

I like the 155gr weight in all Copper or Underwood 155gr Gold Dot. Here is a wax block I made and hit with an Underwood 155gr Gold Dot.

I like the bone crushing effect of hard cast lead but for devastation, a light copper hollow point that opens like a fan blade and tears through soft tissue will make a bad guy anemic pretty quick! I carry the 165 grn. Underwood load in my G29.

Are the 125gr coppers frag nasty or do they hold up? 
What I gather light grain coppers or mid grain lead.

This question lacks the necessary qualifications to have an answer.  We must know what we are shooting.

I tend to favor lead bullets over jacketed.  But for light game or two legged predators, I choose 180 -200 grain hollow points.  Otherwise I take a 200-210 grain WFN.

All loaded to about 1250 -1350 fps.

I prefer a lighter faster bullet for maximum tissue damage. Nosler 135gr at 1520 fps or Nosler 150 gr at 1420 fps. Kinda goes back to the proven - 357 mag 125gr HP load , very effective.

Only qualification is when you think of a 10mm round which do you think of first.  Which in my mind is the one that totally f'd something up making a big impression.  Bottle, can, jello, old fridge, junk car, phone books, critters.  Whatever was your target.

My only point is a 135 grain JHP at 1550 fps is not going to be nearly as devastating to an elk or mule deer as a 200 grain WFN will be.  On the other hand, that 200 grain may just poke holes in a rock-chuck, where the 135 grain would explosively eviscerate one.

So, I can't pick a "most devastating 10mm round" until I know what we are shooting.

Carry on!

The most devastating round was one I apparently double charged. I was extremely lucky and it only blew the magazine up. 

Well since the orig question was not so much about depth,im thinking a self def load. Im staying with the 135 Nosler.Now cooler season,ill use the 180 Nugent.

You know I would have no qualms about driving any of these 156 grain pills @ 1300+ fps...or the 140 grain Barnes @ 1400+ 

Shadow, the OP asked about "devastation" not "carnage".

Well those florescent-green 156 grain Lyman cast bullets are Devastators!
