So I decided to do a little testing on my hunting bullets. Mainly because I could not find much info about the 300g sierra.
any way here is what I came up with

375 Ruger
300g sierra SBT
25yrds into water jugs
.795" expanded
246.5g retained weight 82%
penetrated 9 jugs found in the 10th
+\- 40" penetration


243 win
100g Nosler partition
25yrds into water jugs
.510" expanded
68.1g retained weight 68%
penetrated 5jugs found in the 6th
+/- 24" of penetration

 
The lost weight was due to vaporization for the most part, some fragmentation may have occurred but does not account for the majority of the lost mass.
 
Looks like textbook terminal performance on H20...I have a box of bullets on the bench retrieved from dead game, they rarely look that pretty...Nice job.

As the snow is receding around the area where I long range all winter I am finding many match bullets that were caught by the snow...Most are barely scratched except for the rifling grooves...Kinda neat to think an object could reach such velocity and yet survive so intact.

I gotta figure out this photo upload system they have here so as I can tell and show!

i forget how i caught the bullets, but i once reloaded a shot bullet twice because as you said all it had was rifling marks and nothing else wrong. it was a 230gr 45acp.

With the price of these Lapua's I should reload them...Ha ha...This is a kind of a special place where I pick these bullets up...The ground is impenetrable with a slight upgrade, with deep snow on top of that come spring I pick up lots of clean specimens that I shot threw paper and pumpkins... Too bad I like reactive targets better and most of my shooting down range is at gongs and a big stone I keep painting black, I rarely even see shrapnel from those bullets.

The deal is - Water is a very good media to test bullets in and its gives a good consistent result ! i think better then wood ! JMO :D RJ

Correct.
Although not identical to ballistic gel or actually flesh, it does provide a consistent and repeatable medium in which to compare one bullet to another.
I did several also using "wet pack" (shredded newspaper in the first few jugs), just to have something a little more dense than water alone.

yes. same jugs you get windshield wash in. filled them with water. line them up.

Great idea, I've got to try it sometime.

I've been catching bullets in snow "backstops" for years. It's a sure sign of spring when you find your first "spring" bullet. Here are a few specimens I fired sometime this winter, collected just before we got this latest dump of snow.
