Do any of you shoot solid copper bullets? What is your opinion of them? Are they good SD rounds or just target rounds?
I'm looking at loading 125gr Lehigh Controlled Chaos bullets in 300 Blackout for a SD round. They appear to be awesome projectiles.I've loaded Barnes in .357 & .44 mag with great results.
Drive them hard & fast.
Longer case length. Heavier powder charge. The 300 Blackout won't get to 2440 fps. Minimum velocity is 1500 fps. With Lil' Gun powder, I think I can get up to around 1900 fps.What is the .300 HAM'R vrs. the .300 Blackout?
300 HAM'R AR-15 Rifles - Wilson Combat
The 300 HAM'R offers effectiveness on large game animals with amazing accuracy and low recoil in the lightweight and compact AR15 platform.www.wilsoncombat.com
Interesting video.
I looked at the advertising and the claims quite fantastic and not very believableLonger case length. Heavier powder charge. The 300 Blackout won't get to 2440 fps. Minimum velocity is 1500 fps. With Lil' Gun powder, I think I can get up to around 1900 fps.
To be fair the 300 blackout is based on the 300 whisper that was designed to be a suppressed cartridge with 220 point bullets at subsonic speeds. Means a small powder charge and I have no doubt that people can design more powerful loads for the AR15 rifle.Terminal performance testing on over 2000 Texas feral hogs and various game animals as large as 800 pounds has proven it to kill much more effectively than the 6.5 Grendel, 6.8 SPC, 7.62×39 or 300 Blackout.
The 300 Blackout was designed to use standard AR15 hardware other than the barrel. It can also be loaded to run subsonic as well as supersonic. It's primary use is CQB.I looked at the advertising and the claims quite fantastic and not very believable

It was direct copy of the 300 whisper and many 300 black out chambers will accept a loaded 300 whisper round. The whisper is a proprietary brand name. The blackout is a SAAMI spec version of the 300 whisper. Just what was change that significantly changes the performance of the 300 blackout vs the 300 whisper. Just the loads that are put into the rounds.The 300 Blackout was designed to use standard AR15 hardware other than the barrel. It can also be loaded to run subsonic as well as supersonic.

The video is demonstrating a Lehigh Defense Controlled Chaos bullet shot at 2440 fps in a rifle with an 18 inch barrel, chambered in 300 Ham'r. This is a supersonic only caliber that the advertising is for
Google factoide: The 300 Whisper and 300 Blackout have small differences in their brass dimensions: Blackout 0.004 larger in the neck, 0.018 longer case length and 0.16 longer OAL. Also the Whisper is a wildcat while the Blackout is SAAMI standardized. Apparently those differences make the Blackout the more attractive of the two.
You won't go back to lead except for plinking rounds when you do.Gotta admit, never used solid copper bullets. Good info. I've got a bucket of pennies. I'll be at the reloading store tomorrow, I'll have to scope copper bullets out.
"The grooves in the copper as i understand it are meant to require less force (less Pressure) when the bullet is being engraved by the lands."I have some copper that I plan to load for combat loads 7.62x39 and 300 blackout. They do well on barriers and also on flesh. They seem to raise pressures a bit for full loads.

115 grain wts can be driven a little faster that helps with trajectory.I'm supposed to have some 115gr Controlled Chaos bullets delivered today. I think they will be a bit better for 300 Blackout than anything any heavier than that. I'll load the 125gr. bullets too, but the 115gr will be the ones I keep a mag full of.
These bullets are very well made. The claim is that they are CNC machined. I can confirm that. I examined one under magnification and I can see the machining marks. They are too uniform to have been done any other way.

Your correct out to about 400-500 yards then they fall out of the sky rapidly.115 grain wts can be driven a little faster that helps with trajectory.
