Well this is not what I expected. 

After our previous discussion, why did you not expect that? Did you just not want to consider the things I pointed out, or ??
At some point you might realize that some of us aren't just guessing.

Sometimes you gotta figure it out yourself,

Sorry, I don't believe everything that I read on the internet.  But for the record, you were completely right, I was completely wrong.

I know a manger of a ranch in South Texas who uses a .300 SBR to control hogs.  He shoots dozens a year and he swears by the 150g bullet.  So, yeah, I was determined to give it a test.  Now it's relegated to plinking steel plates, which it does very well, smacks them with authority.

Next up - 150 yards shots with the Barnes and the 125g SST - after I put put my gel block back together.

Hey I don't even ask that anyone take my word for it, just think about the stuff I pointed out.

Pretty cool testing....which is part of the fun.

I always like to see testing pics of gel shot at ,keep at it.

Cp are you making your own gel or buying the kits? What’s your recipe if you don’t mind sharing if you are doing it DIY.

I make my own.  The base recipe is 1oz powdered gelatin to 1 1/3 cups water. 

https://www.amazon.com/Knox-Unflavored-Gelatin-1-lb/dp/B001UOW7D8/ref=sr_1_7_s_it?s=grocery&ie=UTF8&qid=1516674355&sr=1-7&keywords=gelatin


Just mix the powder into cold water.

That mixture goes into the frig for about an hour (don't worry about getting it clear at this step, just get the chucks mixed it.

then melt and warm that using a double boiler, get it hot to the touch, it will be pretty clear by then (clear enough anyway)

then pour it into a mold of your choice (I use Pam so doesn't stick)

back in the fridge over night

Remove it from the mold, done.


It's not to the FBI standard, but it works.

To re-mold cut it into chunks and back in the double boiler or put it in the oven at 200 degrees until melted.

@bknilvr00

We need to do this.

Awesome thanks 

I have used lots of different stuff to catch bullets and test expansion but never the gel itself. Will be nice to test a couple subsonic bullet loadings, I am curious to see if there is much for expansion on.

Gel test #3 – 125g SST at a “simulated” 150 yards.  Simulated in that the round was loaded down to the 150 yard calculated velocity.   Target velocity was 2010fps and it came in just a bit hotter at 2022fps.  That would be about 1135 ft-lbs of energy at impact.

The bullet passed completely through 13” of gel and lodged in the 1st backing sand bag.  There was an exit wound in the bag where it looks like a large piece of jacket exited (unrecovered).   

Recovered bullet weight was 92.5g (74%).  No fragments were found in the gel, many were found in the sand bag.  Damage to the block was extensive, almost severed in half down the middle.  Significant permanent wound channel.

While I’m not thrilled with the weight retention, it appears that breakup occurred after passing through the gel.  Bottom line is this will get the job done with plenty of energy to spare for a bit more range.

Interesting! Maybe it mushroomed at that velocity, which caused the trauma to the gel and came apart on impact with the sandbag. Either way it would sure do some damage to a deer.
