I think Wolf Gold uses bi-metal brass instead of the normal coated steel in their other lines.
Wolf Gold is brass case, copper FMJ, lead core, non-magnetic, loaded to M193 spec. The primer prockets have a military crimp and are sealed. There is also sealant at the neck of the cartridge.
i used that ammo:
1. smells like pure rubbish
2. the recoil increases by at least 25% from say, PMC .223
- i dont find this ammo "worth it". i'd rather pay $1 more per box and get PMC
First of all, you judge the ammo by the way it smells? That's a first for me.
Second, Wolf Gold is loaded to 5.56 NATO (M193) spec, not .223 Remington. The increased pressure and perceived recoil impulse is to be expected.
Just in case you don't know:
"The cartridge casings for both calibers have basically the same length and exterior dimensions.
The 5.56 round, loaded to Military Specification, typically has higher velocity and chamber pressure than the .223 Rem.
The 5.56 cartridge case may have thicker walls, and a thicker head, for extra strength. This better contains the higher chamber pressure. However, a thicker case reduces powder capacity, which is of concern to the reloader.
The 5.56mm and .223 Rem chambers are nearly identical. The difference is in the "Leade". Leade is defined as the portion of the barrel directly in front of the chamber where the rifling has been conically removed to allow room for the seated bullet. It is also more commonly known as the throat. Leade in a .223 Rem chamber is usually .085". In a 5.56mm chamber the leade is typically .162", or almost twice as much as in the 223 Rem chamber.
You can fire .223 Rem cartridges in 5.56mm chambers with this longer leade, but you will generally have a slight loss in accuracy and velocity over firing the .223 round in the chamber with the shorter leade it was designed for.
Problems may occur when firing the higher-pressure 5.56mm cartridge in a .223 chamber with its much shorter leade. It is generally known that shortening the leade can dramatically increase chamber pressure. In some cases, this higher pressure could result in primer pocket gas leaks, blown cartridge case heads and gun functioning issues.The 5.56mm military cartridge fired in a .223 Rem chamber is considered by SAAMI (Small Arm and Ammunition Manufacturers Institute) to be an unsafe ammunition combination.
