I have had a handful of you email me questions about which bullets fragment, which ones retain weight, etc...
A while back we produced an episode of television completely about how different bullets, perform very differently upon impact than other bullets.
They are all made very differently from each other and you can really only see it when you shoot a ballistics gelatin block in high speed video.
Anyone who is interested in this video can click this link:


This video is strictly for educational purposes and we don't recommend any one of them in particular, however we recommend you select your bullet based on how you want a bullet to perform upon impact with an animal.

I think something that is often neglected in terminal ballistics is the effect of twist rate as well as retained velocity through the target.

Re: twist rate

Twist rate, especially with monos like TSX greatly assists in maximum expansion at a given velocity. It helps "spin the bullet open" for lack of a better phrase. A 1/7 twist, for example, will open up a 55gr TSX far better than a 1/12, especially near the bottom of the expansion envelope velocity wise. When you get into heavy subsonic in 8.6, etc the effects of a 1/3 or 1/5 twist are profoundly visible in slow motion gel blocks vs 1/8.

Re: Velocity through the target

When a bullet retains higher velocity through the target, temporary stretch cavity is able to be a wounding mechanism for further along the bullets path.

Morning Rob, Any feeling for how the 300 H&H shoots? How's the barrel condition?

Hello. I see you hunted with Sampie recently. If you don't mind me asking, where did you hunt with him? Zim or SA? And was it with a bow? What did you hunt?

I am possibly going to book with him soon.
Currently doing a load development on a .404 Jeffrey... it's always surprising to load .423 caliber bullets into a .404 caliber rifle. But we love it when we get 400 Gr North Fork SS bullets to 2300 FPS, those should hammer down on buffalo. Next up are the Cutting Edge solids and then Raptors... load 200 rounds of ammo for the customer and on to the next gun!
