Re: Monolithic Expanding Bullets, Weight and Velocity.
I know this is a long thread from a year ago, but still has a lot info. I'm changing from Hornady GMX to Balistix due to availability and especially cost. Just today saw Hornady CX and Barnes TTSX is almost 3x the price of Balistix, and so far I've only heard good things of Balistix. So, with a my 30-06 the difference in speed for 175gr and 165gr is only about 30-50v/s. Because of the better bc of the 175gr it seems a better bullet to be also for longer shots, with a bit more momentum due to the mass difference. Now, my question, with this little difference in speed, but more terminal energy and momentum, will the 175gr open up more than the 165gr? Is it only the speed that cause the mushrooming, or what influence does the momentum/energy have?

Re: Monolithic Expanding Bullets, Weight and Velocity.
The amount of mushrooming is primarily determined by the impact speed. A few tens fps either way isn't really going to make a difference.

Re: Monolithic Expanding Bullets, Weight and Velocity.
There is a Facebook page that hunters post recovered bullets . From the findings shown on that page , it becomes clear that not all locally produced monolithic bullets perform equal and some struggle to expand even around 2300fps .There are some reports of delayed killing where it seems like the projectile did not expand and just went through. The most consistent performers are the ones that have some sort of a expansion initiation mechanism or have some design feature that assists it to expand.

Re: Monolithic Expanding Bullets, Weight and Velocity.
Sorry missed that, ballistic studies.
