weight retention?

non mortuus

"Federal HST 45 Auto 230 gr. 14.00" 0.815" 100.30%
Winchester SXT 45 Auto 230 gr. 24.75" 0.450" 100.91%
Remington GS 45 Auto 230 gr. 10.00" 0.520" 81.17%**
Speer GDHP 45 Auto 230 gr. 16.00" 0.690" 100.87%"

Ok there was a discussion in another thread about which round was the best for self defensive, and someone posted a link to something with the above chart. The last column is bullet weight retention. How can a bullet retain over 100%???
Is the ballestic gel (or whatever) not cleaned off bullets before weighing? [?]

I have done a lot of testing with various media and I aways cleaned the recovered bullets before weighing them.

I've done a lot of testing with the Rem. Golden Sabres in the past. The brass jacket isn't bonded to the lead core on a lot of their loads. It tends to rapture rupture the entire jacket and throw it off at a 30 degree angle to the bullet axis. You talk about a wicked load, the multiple large diameter holes these rounds put in plastic water bottles are unbelievable. Weight retention might be what the FBI demands, but I'll stick to the Golden Sabres for personal protection ammo.
