This means a flatter trajectory as it whizzes downrange. A bullet that retains more velocity naturally retains greater energy as well, increasing the damage it can inflict on impact. Manufacturers often add polymer tips to their bullets to make their meplats i.
This helps to standardize their ballistic coefficient, permitting them to perform more similarly to one another while in flight. A very well-made polymer tip can also create a more streamlined meplat that heightens ballistic coefficient overall.
Many bullets that are intended only for match shooting have polymer tips designed solely to standardize and increase their ballistic coefficients. Is the improvement dramatic? Not necessarily. Many experienced shooters claim to notice no improvement to accuracy when firing polymer tips as opposed to conventional boat tail hollow point bullets. We fired a. The result was a cloudy looking gel block and a highly fragmented bullet. A hunting bullet may include a polymer tip that is designed to promote faster, more reliable, and more uniform expansion.
When the V-MAX collides with its target, its polymer tip rapidly smashes down into its underlying nose cavity. Hornady almost universally uses red plastic tips Hornady has produced.
Sierra uses green and Swift uses black tips for their "Sirocco" plastic-tipped bullets. Military Wiki Explore. Popular pages. Project maintenance. Register Don't have an account?
Now imagine the same scenario with the same bullet at higher velocity and energy "Y". What does the energy Y-X provide in terms of the wounding mechanism? Quoted: Quoted: Quoted: Now we're getting somewhere. Quoted: If I get a chance to read it, I will. But my opinions on terminal ballistics are formed more from personal experience than from reading books.
I've killed a lot of critters with a lot of calibers and bullet types, so I've seen what works and what doesn't. Reading books and forming theories is fine, but it doesn't replace real-world experience. It's lack of penetration with most of the polymer tipped bullets. OTM's dont expand, they fragment. Well said. Why do manufacturers market them as self-defense bullets? Beats me, because they shouldn't.
And your question has been answered - they're varmint bullets with inadequate penetration. The why has been discussed a few posts up. Yes, your post and a couple of the others were very informative. Well, they're only responding to customer demand, usually driven by the false belief that there is an significantly reduced worry about overpenetration.
They have plenty of penetration for humans. There's a reason the FBI requires a 12" minimum, and some of the poly-tip bullets come nowhere near that. Do you understand that "energy transfer" is not a wounding mechansim for small arms fire? Do you understand that not all shots taken in a defensive shooting will be straight-on frontal shots? The FBI requirement for bullet penetration in bare ballistic gelatin is 12" - 18" for a very good reason.
FACT: Most polymer-tipped. Sorry if I was mistaken. I've noticed something on this forum, that whenever some supposed "expert" posts his opinion on a subject, it becomes the gospel truth. Yeah, the polymer tips do make a quicker kill. Where is your scientific data to back up this assertion? Not to sound too harsh, but do you truly realize what you're saying?
There's a reason they are the experts - they do it for their living, and they have more experience than anyone else in the subject. That makes it more than just a random opinion.
The Wright brothers proved that airplanes heavier than air could fly; would you call their experience just an opinion? Not true. Just because they're polymer tip doesn't mean they're going to fragment excessively - see the Nosler Accubond for example. If there's fragmentation, it's the guts that get the fragments. That's not to say you couldn't end up with fragments in the edible meat, but it's not that big of an issue. You thought wrong and you posted erroneous information.
This is a technical forum. Try checking your facts before posting. As I already stated, the Hornady 5. Martin Fackler disagrees with you on the subject. Do you seriously want to debate that you know more about the subject than he does? Fackler, M. Ballistic Injury By Dr. The Wisconsin DNR recently did a study on this subject, and they found that all polymer tipped bullets left more lead fragments in the meat than a traditional soft-point bullet, up to 18" from the primary wound channel.
Advantages of using a Nosler Hunting Bullet Why target bullets aren't designed for hunting. Why do you list maximum and minimum velocities for your bullets? Understanding twist rates and bullet stability. Does the lead in the rear of the Partition melt when fired out of a rifle?
