Will a 123g and a 173g bullet do same damage if E is the same at a given range?

[Kristian_Jensen]

Lowlight posted an article about US adopting 6.5CM for DMR rifles. There was a picture with some graphs that showed that a 123g 6.5 does E456 at a 1000m and that a 175g .308 has the exact same E

My question is, does that mean both calibers / bullets will do the same amount of damage to a target?

No the amount of energy does not equal the amount of damage...it equals a random number calculated by the bc, weight & speed..... this energy number i havent found to be very definitive for anything except when comparing very similar projectiles...but theres way more variables involved such as bullet construction & shape,frontal area, active material (shrapnel), angle of shot,impact velocity, bullet stability and target material....

This has been my experience as an avid elk hunter

The BC numbers for the 175 look pretty beat down to me or am I missing something, that looks closer to the 168 bc.

0.475 is the Litz G1 for the 175 SMK.

Numbers are for number guys, paper/steel targets are for target guys. In WW II it took 200K + rds to kill one enemy. Korea it was 275K +. V/N was 350K+. So with that, numbers data indicates all bullets are becoming less effective. Technologically we have advanced by leaps an bounds from WW II yet we are still engaged with cave dwelling, goat fornicators, after how many years? Yet this new round is the be all for killing the enemy at long? I applaud Creedmore, perfect job selling.

I'm pretty sure the numbers indicate that newer weapon have more rounds in the magazin and higher ROF

I think the main point to takeaway is a reduced sized cone of fire, IE; greater accuracy should increase hit probability.

Understood, wasnt trying to start a pissing match it just seemed low but I have never used the 175smk have allways used the 178amax since I also used them for killing deer and hogs.
