WP3S bullets data

[Grimstod]

Does anyone have any data or know of any for these bullets?
I see they even have some 6.5mm bullets in 160gr. Cant imagine how tight a twist that would need. They only list BC values for the 30cal bullets. I can't find anything for the 6.5mm. The 142gr bullet would be oaf interest to me.

These bullets have been the subject of hot debate on some internet forums regarding their actual performance vs. advertised. I'm not commenting beyond that, but it may explain the reluctance some have for engaging this question.

Thank you brian. I sorta figured they were a little inflated looking in their BC.

I would bet if you called if you called John at W3PS Bryan he may send a few to test. The ones I have seen used did shoot allot flatter than most and are looong! But I have no idea if the posted bc's would be right. John is a stand up guy and I am sure would love the information. Matt

Grimstod......it's easy for you to sit there and say those things beings you haven't used the product. Most guys that have used the projectiles thus far are competitive shooters that don't run their mouths about what their edge against the competition is. You'll have your long range hunters that report back here or there but beings it's so new par say as well there isn't much out there in the public forum about what we do.

Bryan has his reservations to finalize the debate he spoke of already and the BC's are calculated using Berger software along with another program. Litz has his own specialized way of verification on BC's and will be done very soon I'm sure. .....and Eric at Berger burned up my email for a while asking about this or that so it's definitely sparked some interest for certain.

Everyone who knows how to load VLD'S that has used them has been 100% satisfied and that's all we can hope or ask for. If you need us to answer any questions feel free to email me direct at John@whiskey3precisionsystems.com

Ya'll have a great week fellas....

John,

Quick question for you.

With a higher density tip, would these projectiles tend to stabilize a little more easily that standard empty-tipped bullets? My intuition says that the instability of bullets is the result of the center of gravity (mass) being behind the center of pressure. If the tip moves the center of gravity forward, I would guess that the twist rate required to provide stability would be reduced.

Any merit to these ideas in your experience?

Busdriver, I wouldn't say that the steel or aluminium balistic tip brings more density to the front end of the bullet with this design because steel and aluminum are lighter in density than lead and copper combination of a traditional lead core bullet smk for instance.

Fact of the matter is from our experience lead core copper jacket bullets with at least 40% of the weight of the bullet in the rear portion of the bullet fly better at distance especially in the transinic zone when the bullet starts slowing down. That is why lead core copper jacket bullets perform better at distance and in this zone for stability as opposed to solid brass or copper bullets. The ratio of weight is almost too balanced in most solids. You can manipulate the weight ratio during the manufacturing process easier with lead core bullets as opposed to copper or brass as well because lead is heavier than the other materials.
