You don’t really know that, they could also have increased the MV past the extremely low figure from 1990 and you still don’t know how much of that 700 is K5.
yes, the charge was changed from that point so we know the muzzle velocity is wrong. We also KNOW the diameter is wrong for this round:
final diameter was 25mm for the penetrator
I did state this wasn’t production, but you’re still using the 700mm+ figure and comparing it to the game which you cannot given its RHAe, meaning a complex target that you don’t know the make-up of.
There is also no RHAe figure for this pre-production round anyways so comparisons cannot be made. There is a manufatuers RHA prediction but with no context.
Well, not like we have production data to work with :)
im not? i havent compared it to in game because i know we cant compare without the test data.
Do you have any figures for the percentage of DU in CHARM3?
the increase vs what gaijin is currently using is 5mm in length and 1mm in diameter, so not to any significant amount, no.
appears to be a 99.6% DU, 0.58% titanium alloy
Cheers.
So, even if you use the lowest possible figure from that source (99.25%), GJN is modelling the titanium in the sabot has having negative mass, looking at the density they use for the L27A1, which is more representative of numbers I’ve seen for US DU penetrators.
“It’s too much work for us to change the density value of British darts.”
US DU staballoy (which the UK uses) its nominally 0.75% Ti and the density is usually given as 18600.
L26 uses staballoy, we cannot be sure this is the case for CHARM-3, and actually this study appears to show it is not the case.
Titanium is alloyed with uranium in DU
munitions to increase fissile strength at a level
reported to be ;0.75% by weight. The current
analysis indicates a slightly lower replacement
(0.58%) which could be due to uneven distribution
of the two metals in the processed material
No your own source more or less backs this up
Sintering DU is not an easy process, so some variation is perhaps expected.

its a relatively significant difference in the titanium concentration, and about 0.1% was silicon, this could suggest a new alloy, iirc this was a study comparing to staballoy hence why they mentioned the 0.75%.
I don’t think its conclusive, and neither did they. Regardless this would only represent a change in density to 18650 (vs 18550)., so idk what math some of you guys are doing.
omg it is weibo…
He is a ZOV supporter, and his main idea is L27 is shit
