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

Acceptable accuracy I assume?

About 1-1.25 moa in my tests and 15 shot groups. Completely acceptable. Not some kind of extreme tack driver.

Has anyone compared these Bone Frog loads to the BH?

@h2so4 , you have any comparative info on this?

 

[Chris_in_Idaho]

The 70gr TSX is relatively unique in the mono world. It was not designed for max penetration. Very common to catch them on the offside.

Do they get a noticeably wider wound channel than typical monos?

 

[fwafwow]

Thanks. I'm hoping for someone who has shot both from the same rifle. I have some Black Hills and paid $1.38 ('23) and $1.45 more recently, and they are currently going for ~$1.50. Maybe I need to just get some Bone Frogs - for science.

@Bluumoon, I think he’s done some comparisons of ammo from the same the same rifle.

Please be patient with my ignorance. Can I shoot the TMK 5.56 ammo through my .223? The internet is telling me .223 in a 5.56 is fine but not the other way. I've been shooting the 73gr ELDM but I'd like to try the TMK. I don't hand load and no one ever seems to have .223 TMK loaded. Thanks

Absolutely it’s fine. As is common, the “internet” is wrong.

 

[h2so4]

@fwafwow ive got some comparison. I’ve posted them previously but if you send me a message I’ll send it all to you.

Short version- The black hills is faster and the bone frog groups almost as good as black hills, maybe equivalent.

Negative on the BH

For every 223?

I know it's fine in the Tikka T2X

 

[Schmo]

Never heard of that one

Depends how the throat & leade are cut.

 

[Schmo]

I would say any quality 223.

 

[mt terry d]

I'd edit my previous response but that might lead to confusion.

I mean if it’s loaded to SAAMI length (2.26”), it works

Yeah I just had to give you a hard time! I knew what you meant

18” 22-250 77 tmk 180 yards quartering away. Bullet went behind shoulder and exited opposite shoulder. Buck ran 60 yards or so and tipped over.

If your standard is "it fits and I didn't die," then yes.

If you want to be operating within the designed pressure, then it depends on the leade.

A 5.56 chamber has a long leade so the bullet gets a head start before hitting the rifling. This lowers pressure. Also, it's loaded hotter so even with the long leade it's higher pressure than 223.

If you put that 5.56 in a straight 223 chamber, where the bullet engages the rifling as soon as it moves, you get even higher than 5.56 pressure.

Many "223" chambered rifles, including the T3X, have a more gradual leade than the original "223 Remington" design, so they handle 5.56 fine.

In my Tikka

I think Bone Frog and BH are comparable. In my 20" Tikka 1:8 stainless:

-35 rounds of Bone frog 77tmk. 20” tikka stainless barrel. 2747fps average velocity. 44fps spread. STD dev. 13.6. Done at 82 degrees.
-59 rounds of BH 77tmk. 2728 average velocity.

This was 2025 production Black Hills, which some say has been reduced in power, but I've also seen that denied.

Having played around with 100 rounds of each, I would buy whichever is cheaper.

Yeah. I think any modern, quality 223 is going to be fine. In a Tikka for example, the same action can be used for 223 or 300WM. So how is 5.56 gonna be too much pressure?
