High BC copper bullets?

[swampy14]

Is there any high BC copper bullets that can be used at extended target ranges? The Cutting edge bullets seem to high bc's but I dont know how accurate those are

Hammer has a new HBC bullet they just introduced.

More skus for Hammer? Geez

I have experience with the Barnes lrx. Has anyone experienced the cutting edge bullets?
They have a 125gr solid copper with an estimated g1 bc of .530 and a g7 of .273?
Is that accurate? They also say reliable down to 1600fps

PVA Cayugas.

I guess I don't understand the BC calculations because copper bullets are all very long for weight compared to lead. The 6.5 127 LRX looks like a javelin but doesn't have an exceptional BC compared to some other bullets.

Coppers will always yield lower BC compared to traditional high BC target/match bullets. Cutting Edge has been used by extreme long range shooters for years.

They will never shoot good unless your have a non standard fast twist rate barrel with a long COL and tight jump to the rifle lands and grooves.

Published BCs are subjective, different test environments and velocities manufactures skew the numbers. I however would think the Cutting Edge numbers should be close but you have to compare test velocity speed and BC results when making your decision.

With all the modern Lab Radar devices these BC numbers are published by others as well. Its worth digging around and seeing comparable results from their data/BC numbers.

Barnes LRX
Hammer HBC, even their HHT line has some good coefficients.

The problem with high BC solid copper bullets is you typically need a fast 8 or even 7 twist barrel thats custom throated to properly seat the bullet for best case volume, to get that velocity needed to truly take advantage of the bullets BC, safely. Done properly though, they fly very accurately and hit hard.

I have used the Barnes lrx with good luck, I have harvested many whitetails and pigs. I even pushed it out to 550yds. I wanted to try 1000+ but the Barnes seemed lacking and moving with the wind.

The goal was to pick a bullet that can be used for range/target and hunting as well. I like the idea of bergers but the way they fragment seems like too much of a mess. I like getting full pass throughs but maybe someone can better explain. Maybe I try the federal terminal ascent

The farther out the game animal, the softer the bullet needs to be to open up properly due to lower impact velocity. Solid copper bullets come in two "flavors" those that mushroom (Barnes) and those that shed the mushrooming petals (Hammers) shedding weight similar to a softer [lead] bullet.
Barnes typically need a minimum of 2000fps at impact to properly mushroom. Hammers need a minimum of 1800fps to properly expand and shed. (supposedly their HHT line needs only 1700 to expand, I hear anyways)

CE and Apex. CE have been fairly accurate for BC.

McGuire Ballistics and Hammers new HBC are pretty decent numbers.

Yes, those are in line with the BCs as tested/listed by applied ballistics.

Not the case typically with barnes LRX and especially hammer bulllets.

Here is a list of BCs for many copper bullets. I threw a few lead bullets in for comparison. (SST, ELD-M and ELD-X)

Send me number for PVA, Macquire etc if youve got them please.

Ive had good luck with Lehigh Defense Controlled Chaos and DRT

PS- I would love any corrections to the BC number's i've compiled in the previous posted list. I do not have access to Bryan Litz's book or any other "truing." So all of these are published numbers by the manufacturers.

PPS- There is a Macquire Copper Rose thread on this forum that calls to question the manufacturer's published BCs. Form trued 6mm version of the bullet before shooting an elk and shared that data at that thread. He landed at .45 which is pretty darn good for such a light bullet.

Cutting Edge bullets have won more elr comps than any other bullet. Their accuracy is second to none.

PVA Cayuga have been good for me. They told me they will tumble down to 1400 FPS.
