LIGHT BULLETS COMPARED TO HEAVY BULLETS

QUESTION:
How would wind affect light bullets such as the solid copper GS Custom HV bullets?

ANSWER:
Fortunately weight has nothing to do with wind drift. Check any good reloading manual and you will see that only two factors govern wind drift - speed and ballistic coefficient. The faster a bullet is driven and the better the ballistic coefficient is, the less is the wind drift. These factors give a distinct edge to monometal bullets over jacketed lead bullets and they will be less affected by wind. There is a comprehensive article on wind drift here.  

QUESTION:
Is penetration and terminal performance adversely affected by the fact that you recommend HV bullets so much lighter than jacketed lead bullets?

ANSWER:
Terminal performance is governed by three factors. The momentum and energy the bullet has when it arrives at the target and how the bullet deforms and breaks when it strikes and penetrates.  

It is a well known fact that solid copper bullets do not lose weight as jacketed bullets do when stressed on impact. With most calibers the recovered copper bullets usually weigh more than the initially heavier jacketed lead bullets after impact.

When a solid copper expanding bullet is designed for reliable expansion on impact, the higher speed possible with a lighter bullet and, especially with HV and FN bullets, actually deliver more momentum and energy to the target than heavier conventional bullets can.

There is more information available here on bullet design and momentum and energy. 

QUESTION:
In a nutshell, what are the advantages, if any, of lighter monometallic bullets over conventional bullets?

ANSWER:
There are only two things that govern success or failure in any shooting activity. Shot placement and bullet integrity on impact.

With HV bullets you have the advantage of higher speed resulting in flatter trajectories, less wind drift and shorter time of flight. These factors improve your ability to place the shot more precisely.

GS Custom bullets are designed to deliver the best terminal performance possible. HV bullets expand reliably from 1500 fps and cannot shatter on impact.

GS Custom Bullets, situated in Port Elizabeth on the East Coast of South Africa, manufactures solid copper, turned, monolithic bullets for hunting and sport shooting. These bullets are used by hunters on several continents, hunting from the smallest of antelope to the largest of dangerous game, using the smooth HP bullet, as well as the more popular HV, FN and SP bullets with the patented drive band concept. GSC bullets are configured for the highest possible ballistic coefficients. SP bullets are mainly used for sport shooting. All GS Custom Bullets are moly coated.
