Meplat Uniformer.  That made me ponder which is a greater merit for a match bullet.  The nose (aerodynamics) or a consistent weight?  In a perfect world, with all variables thrown aside, which do you think would be a greater asset?

Another thought is that if you use a quality match bullet (Berger, Sierra, etc.) that are very close in weight, and shave down the nose with a tool, would the weight not be close enough with each other to really not matter?

Thanks for the link, but he really didn't touch on the merits of uniform weight v. aerodynamic benefits.  Although it would be difficult to form a scientific process to compare the two, I wonder which is a bigger benefit.  Good link, though.

From the article:  "Note that the removal of material results in negligible weight loss (less than one grain), so mass isn’t a factor.  Only the additional drag of the blunt tip is responsible for decreasing BC."

another way of dealing w/ meplats-

www.whiddengunworks.net/pointingdie.html

John Whidden says pointing the meplat vs trimming it yields a 10% increase in performance.

"With our bullet pointing die, we can make the meplat smaller rather than bigger. Consider that a little pointing will do a lot of good. Typically with the bullet pointing die, we can close the meplat up to about half of its original diameter. Here’s the kicker-by closing it to half of the diameter, the surface area is only one fourth of its original amount. This is the reason the pointing die is so effective.

How effective is it? Again talking about bullets typical for long range competition, we can gain about five percent better wind drift compared to bullets right out of the box. We are also getting an increased consistency of BC because we have reduced the size of the imperfections at the meplat. Better accuracy down range and better performance is a winning combination.

Let’s compare trimming meplats with pointing them. Since trimming yields a five percent reduction in performance and pointing yields a five percent increase in performance, there is a ten percent difference between the two. How big is a ten percent difference? A 6.5-284 is about ten percent better than a 6mmBR at 1000 yards. You can actually point your 6mm BR’s bullets and be on equal footing with a 6.5-284. This is a huge difference for just pointing a bullet."

My opinion is it would be best to have consistent meplat in your scenario.

To fully understand the difference, go to this page and read the articles on teh 155 SMK, Berger, and Lapua bullets.
