Hello all! Below are all of my results for the 300 Winchester magnum. Please see the associated card to see the ammo type, velocity, firearm, and penetration information. Please feel free to also add any results you may have had, as this could possibly turn into a library of sorts with multiple contributors to help people pick which ammo to stock up on, and what ammo is all hype. In the case of non-factory ammunition that is tested, please bear in mind that you only use the listed load data at your own risk. Safe in my guns does not mean safe in yours. I am also open to testing any ammunition that you may have (factory or non) but if it is non-factory, I will need a breakdown of your load data/process before I pull the trigger on it. If you have an interest in that, PM me and we can discuss. If nothing else, please enjoy the results, they were certainly fun getting!

Gel data: 20% ballistic gel made from Knox unflavored gelatin (and for the money minded, great value unflavored gelatin powder also works fine), and a few drops of cinnamon oil to help keep mold down and prolong the life of the gel (plus cover the wet dog smell of the melting gel).

Also, I don’t pretend to think that this method is the best, most scientific, or even preferred method, but it felt a bit wasteful to just hold onto the data without sharing it with others. So here it is! Enjoy

165gr Barnes TTSX.

Of mention, the first shot penetrated 33+ inches of gel and then zipped right through a 3/4 Particle board. The second shot cleared 33+ inches of gel before penetrating a 2x2 piece of cedar and lodging in the particle board. The “petals” detached after the 16 inch mark on both shots.
