.223 for bear, mountain goat, deer, elk, and moose.

I plugged in some number for 77gr TMK out of a 20" barrel and got a minimum expansion threshold at 210 yards? This seems way off as I was thinking at least 450 yards.

What's the consensus on ~1800 fps for 77gr TMK with a MV of ~2800 with a 20" barrel?

Way off. Over 500 yards. I get 500 with 2710 out of a 16”

You have an input or program error. 2800 fps gets you 500 yards at sea 600 ft above sea level.

With Stand1 77tmk ammo, I get 2771fps MV out of a 16 inch barrel... which at my elevation (4500) gets me to 570 yards before it drops below 1800fps.

With Black Hills 5.56 77tmk ammo, I get 2690fps MV out of the same 16 inch barrel, which gets me to 525 yards.

I would guess you should be at least 100fps more with a 20 inch barrel... I think I was around 2925fps with the stand1Armory stuff out of a factory length tikka stainless superlite (22 inches I think?)... that got me out to about 640 yards and 1800fps with the longer barrel.

Not sure what distance you're asking about but I'm at 1800 fps at 675 and have been
plinking at over 1000 with it without issue.

Hand loads? Whats the recipe?

 

[mt terry d]

Hand loads? Whats the recipe?

Handloads, yes.
No offense but the person who shared this load with me made me promise not to share;
seriously.
I will say it's on the hot side.

 

[PNWGATOR]

What recipe are you after?

What recipe are you after?

The one that pushes a 77grTMK in a .223 to 1800fps out to 675yds with an 18in Tikka.

Can’t help you with that.

I’m certain it exists, but I’m not one with that level of first hand experience.

22PRC
22UM

Above is where I’d start based on your expectations.

Until someone hurts themselves and starts trying to sue. This is the society we live in these days. I would like to assume there aren’t many of those types of people on here but ya never know. I’m not saying I wouldn’t share the recipe but can understand his pause.

 

[Nomosendero]

It's not dangerous to list the components and not give the charge weight, at least not for me.

Kinda like when someone shares their honey hole with you with the understanding that you won't share it. Man's word is his word.

Yeah, but depending on the person it might not be a real tight bond.


It's not really like it's a secret. It's been discussed on RS in other places.

Okay, back on topic kiddos

Only a short time till another massive influx of dead critters thanks to
223 & TMK

I'm getting excited!!!

Don’t use too much TAC with a 75 grain ELDM.






When it gets warm your Tikka firing pin assembly breaks.

Weird.

I am here to eat crow, having learned my lesson

Overpressure is a thing. I’ve seen it. And when you’re pushing the envelope and then the temperature gets into the 80’s, you’re fúcked. Remember the 75 gr ELDM load I was so happy with? The one some of you guys said whoa Nelly you dumbass, that’s overpressure? And then I sai...

If it grouped good and that was a plastic bolt shroud I would replace with metal and try again…

I did not see this billet (or style of bullet) mentioned in the entire thread. Is it because it is not consistent?

What about frangable 223 / 5.56 ammo? I have only seen YouTube videos in balistics gel so I literally have nothing to say it will work... but look very cost efficient and like it would do the same thing (in theory) as a TMK...

Any 1st hand knowledge out there?
