Good evening everyone, I load for 6.5 creedmoorLapua Brass and now just bought myself another .223, I just wondered who’s using GGG Brass and what you think of it as I can get a plentiful supply for free, just d primed two cases and removed crimps,one with a drill countersink but and one with my deburr tool and they look decent Brass, I was told Brass is slightly thicker and was loading 23gr N135 behind Amax 52gr with my old Hornady Brass for 5 rounds under 5p at 100yds, would pressure be the same with that load using GGG brass or should I start slightly lower and work up ?

start lower work up, standard practice, I use only GGG brass in my .223 and have started to see brass smearing below max charges of N140, so have dropped 1/2 grain, velocity didn't drop more than 50fps and no more marking, so I'm happy with it

GGG brass is good stuff,and I’m getting around six reloads at the top end of the scale before the primer pockets start to loosen off.

Although a de burr/csk tool will work, it is worth considering a swager to remove the crimp for two reasons:-
1- It is much quicker
2- It is much more consistent, and allows the bare amount of material to be removed.

Yep, I use GGG for .308, and I've got 600 odd GGG .223 ready for use when my current LC brass starts to die.

Took advantage of the hot day to ultrasonically clean over 1000 .308 and .223 GGG cases.. they dried lovely in the sun..

I use GGG brass for my .308,s. Its good stuff just need to remove the crimp.

Thank you everyone for your help
