What kind of velocities are you guys getting with the 16” with tmk?

2,600 to 2,650fps MV.

Fiocchi\GFL is good brass.
Well done on the pigs.
Lithgow rifle?

I wouldn't call it good brass. But I would call it good enough brass. I dont think ive ever seen 223 gfl brass with a centred flash hole. Like not even one. One of my universal decappers doesnt like it due to this but its minor. I found not difference in precision vs the lapua and starline i have here though. I annealed all mine since I have access to an Amp at the range and need to kill some time between strings.

I'm sure the brass is OK but the primer pockets on half have that annoying crimp or whatever you call it in them and I can't be bothered cutting that out at the moment. Red Earth have made some bulk .223 ammo for the Australian market that comes with either 55gn Vmax or 55gn Hornady soft point, so I might buy 250 or 500 of those and then use that brass instead.

I loaded up 20 rounds in random brass the other day that I have laying around - maybe 5-6 varieties all up. I was hoping I'd fluke something good. Of course, the accuracy wasn't great, and I only have about 50-60 of any one kind of brass, which is annoying.

Yes, a Lithgow La102 Varmint with a ZeroTech 3-18x56mm scope.

You may be suprised the the crimp is so light you can seat primers fine unless its different to my "crimped" g.f.l brass. By the second seating I couldn't tell with the hand primer (never could seating on the dillon) and a few i just gave a quick spin on my vldchamfer tool and it was done in a 5 seconds maybe including picking up and putting down the brass

2,600 to 2,650fps MV.

What kind of load are you using? that seems pretty hot. Sierra manual says 2650-2700 for a 24” barrel. ~25fps per inch I was figuring I’d get more 2450ish MV for a 16”

The crap I loaded and brought to Montana was running 2805...I'm going to pull them or wait till Winter. A combo of new lot of powder, sun and summer temps.

16" Tikka Lite Profile 8 Twist Blued Barrel. All shots have been suppressed with a Dead Air Nomad 30 suppressor and all shots have been with 77 TMK factory black hills 5.56 ammo.

Velocity stabilized right around 75ish rounds or so. I remember it being somewhere around halfway through the second 50 round box...

This barrel is fast, very fast. Around the speeds I've seen from multiple 20" Tikka barrels.

~2650 with book max staball

6.5? HD? Match? which staball?

 

[rabbithuntr]

Both actually 6.5 is a little faster but I can shoot both with book max almost interchangeably, I’m sure a better shooter would notice more of a difference than I.

Nah, it was painful. Half because of the crimp and half because my Lyman hand priming tool is annoying. I broke some primers, etc.

I'll need to get a much better priming tool in the future if I want to shoot and reload bulk .223 ammo.

There must be variations or differences between GFL brass. Maybe different type runs. I have never struck or had a problem with primer crimping and have loaded many hundreds of them. My brass is once fired bulk factory ammo from a pest contractor.

Ive got both GFL and G.F.L headstamped brass. Both have what id call a very light crimp.

Keep your eyes peeled for black hills 69gr and 77gr tmk coming to internet shelves soon. Recent lots should arriving to outlets now through next week! It’s been a while since I’ve seen the 69gr tmk.

I’m definitely interested in some of the 69-grain stuff.

Yeh, KI guess there is some variation in it for sure. All this brass was being shot from the same boxes of ammo but some would take primers and some wouldn't. I can easily buy once fired ADI stuff in bulk OK but I have a chance to get some bulk Red Earth ammo so I'll explore that option first.
