Hawk bullets in 577 Tyranosaur.

25 January 2002, 04:13

Do the Hawk 750 grains soft nose bullet 0,35 at 2500 f/s expand easy in a 200 kg moose if i hit bone.

How big diameter would the bullet have if it expand to max.

How big hole does that bullet do in the moose if i shoot at 40-50 yards....?

Some buddy who knows....

Have some buddy shoot a elk whit a 585 Nyati or 577 Tyranosaur. Please tell me the effect.

I haven't tried that combo, and doubt anyone in the world has. My expectation would be that the thin jacketed bullet at that speed would come violently unglued at impact, and may likely produce a ghastly surface wound.

I would also venture to say that you, and nearly anyone else in the world would be unable to accurately shoot that load in the field in a gun of a weight that one would be willing to carry.

In all honesty the 585 and 577 T-rex are novelty ego guns. They are well past the point of shootability and practicality. Yes, I still fancy the thought of building a 585 Nyati, though I think the 500 Jeffrey may prove my limit.

Overkill, I have used hawk bullets in my 577 T.rex. at reduced speeds (2150 FPS). If you try and push a Hawk Bullet that fast you will have pressure problems for sure. The Hawks are a very soft bullet that will seal the bore not letting propellant gases escape past the bullet, this can and will elevate chamber pressures. I have run my T.Rex. as fast a 2608 fps. with a 750 gr. Naval Ordnance bullet with no pressure problems. However for high velocity loads I now use Woodleigh Bullets, they will give the explosive expansion at those velocitys although that much velocity IS NOT NEEDED.
A better choice might be a Woodleigh 650 gr. bullet at 2400 to 2500 FPS.

Paul, As you know recoil tolerance is very subjective, what is intolerable to one person is tolerable to someone else. I have no problem shooting my T.Rex. at high velocitys and with great accuracy. And I don't think it is a ego trip, "IF" you can handle a rifle this powerful.

Mitch, Where can one buy Naval Ordnance bullets? I can't remember seeing them listed anywhere on the net.

Overkill, I don't know about the Hawk's but I have fired 750 grain Woodleigh sn's into a rack of wet phone books at about 2400fps. Don't know if the books can be compared to a moose, but let me tell you this: The hole was much bigger than my fist. One thing is for sure and for certian. If the moose is still standing he wont be happy:-)

Rune, Naval Ordnance has no web site. They are a small one man operation. The batch of bullets I got from him were not very good. Poor quality control,some of the 750s I ordered weighed as much as 768 grs. If you are still interested I will try and find his phone number.

Mitch, that was not very uplifting news.
I think I will try TCCI bullets next time. Thanks anyway:-)

Mitch, my criteria is a rifle one is willing to pack all day, would you find a 10# 577 T-rex shootable from field positions?

And come on, you must admit there is a certain satisfaction in shooting the big bores proficiently, maybe ego trip is the wrong term, but I know I imensly enjoy shooting them.

OK, I will fess up. I shot a Hawk 750 grain .035 jacket bullet into the shoulder of a recently deceased elephant from a distance of 10 feet. The velocity was 2250 fps. The bullet went through the shoulder but only had about 1.5 feet of penetration. The bullet was squashed like a pancake. Although I have not weighed it, I would say the bullet lost half its weight in that distance and expanded to about 1.5" diameter.

If you were to use a .065 jacket Hawk and shoot a moose (which is less heavily armored than an elephant) I suspect that penetration would be substantially improved.

Paul H,

My 585 weighs 13.25 pounds and I packed it myself all day every day (except the noon nap), going 8-12 miles per day typically. I consider a 10 pound gun light. Even my 338 weighs over 10 pounds with a scope.

Paul, A 10 lb. 577 T.Rex. you are joking
of course. Such a rifle is much too light for such a big cartridge. The weight of the rifle must match the cartridge it is chambered for. My T.Rex. weighs 14.3 lbs. and before my illness I am sure I would not have a problem carrying it all day. Of course I get satisfaction shooting my big bores well. If I could not shoot them well I would not shoot them.

Ha! And I thought I was the only one that liked "fat" rifles!

My .375 H&H M70 just breaks 11# stuffed and scoped. So easy to shoot from any position....
