you guys have all seen the exquisite solids Macifej is producing in 505 Gibbs. They are like jewelry, they feed well out of my CZ, and they hit like Mjolnir. They also mike to four digits to find the variance in diameter and in the .4-.5gr weight tolerance.

I'd like to see a quality, made in USA 550 caliber bullet just like it. I understand most of you considering having one built want to see the product. The issue is $$$. He cannot afford to tie up a programmer and machinery and materials just to see if there is a market. These are very specialized bullets.

Soooooooooooooooooo. He will make a (very) short run at a zero profit margin to help out as much as he can. Anybody who would is seriously considering building a 550 needs to let him know. Ten guys who would order fifty of them will get this done.

You can't kill 'em sitting on the porch.

GO TEAM 550!

If you are talking about a 700gr solid and not to take anything away from this bullet maker. I have 4500 700gr .550" barnes banded solids sitting in my shop.

RNS - do you have any .505 Gibbs formed Brass? OR any .577-700 Brass?

I might as well mention that we already have 700gr FN's packed in 25's and 600gr HV's also packed in 25's.

do you need 577/500 or 577/700?

jeffe

I have some 700gr .550" GS FN in stock

the only thing close that I have in stock is 577 NE 3"

I was looking for some .577/700 as made by Dieter Horneber in the lovely village of Furth.

I need a plinking round!

......OK so what twist rate does the .550 ,700 require ???

The 550 Magnum has a twist rate of 1:18" and a 700gr copper FN will therefore have a stability factor higher than 3.5. Anything over 2 is good and anything over 2.5 is pretty much academic.

.......Thanks for the reply Gerard.. PacNor lists a 16" and a 20" twist for the .550 barrel Which would be best ??

If I built one for myself, it would be a 16. It is impossible to go too fast on the twist for DG work and a 16, with the right bullet would be a spectacular long range machine.

What's your idea of long range Gerard??

Over 600.

........so , the 16" twist would work with the 600 gr HV,s I suppose .............. ...I shouldn,t have clicked on this thread .......It kind of comes down to , can the gun be run fast enough to be useful in a charge situation, where mulitple shots may be required .......Jeffosso,s vids of his 550 Express show a pretty manageable level of recoil .....

Having shot jeffe's Express, and tiggertate's Mag. You had better be very good at recovering from recoil, for a fast follow up shot. The rifle HAS TO FIT YOU VERY WELL, a poor fit = a poor recovery. I have found tigger's Mag easier to shoot than jeffe's Exp, jeffe is 6'4", Harry and I are about the same height and we do not have jeffe's gorilla arm length. That said, I can "shoot'em" but I do not want to shoot really fast follow up shots. Makes my head hurt.

If I ever get to go, and need fast follow up shots, my Lott will suit me just fine. Could go into the .500"/600gr/2250fps class.

Is everyone here on the Big Bore forum a big mutant freak?!?! Holy crap! I know that ISS, RIP, Jeffe, PROF, SAFARIKID, Gatehouse, and all the Canucks are huge guys! At 5-11 and 180 lbs (fat) I guess I am the midget! Of course I am the meanest of y'all so I'm not too worried about hangin' out!!

.....5'9" 255 lbs.........PURE MUSCLE , GUTS AND SPEED

Don't let the vids fool you.. the stock fits me PERFECTLY, and was designed/setup/executed by me knowing how much of a monster it it would be.. also, i have trained a long time to shoot bigbores, and when we took that vid, i was shooting 50+ rounds a month out of it.. and I do have my "recoil judo" going with me.. the rifle and I move alot more than it looks, but my recovery time, in a 550 is fast

Rob can't be 5'8, and 470mbogo is about 5'10 and slim built ..

i am quicker than those stronger than me
stronger than those quicker than me
meaner than most
more stubborn than all

or
strong like bear
smart like tractor!

I'm 6' and 225 lbs of the human equivalent of Kobe beef. And just like the cattle, that took a LOT of beer.

I can twist a top faster than those stronger than me,

When a cork has to pop I am stronger than those faster than me.

I'm not very mean but when the bottle is down to the last shot, you better be fast AND strong...

Masifej
Don't forget Canuck 32. He is 6ft 7 inches and 370 lbs. He shoots his 470 Mbogo like a BB gun.
Like Jeff said I'm 5 10 and 170 lbs and able to recognize tall buildings at a single glance. I might even race Tiggertate for that next beer.
Take good care,
Dave

Gotta get that man to Dubai. First we'll coax Saeed to throw in a Safari for Canuck32, if he uses his "throwing gun" loads in the T-Rex. After seeing the video of him shooting the 470 Mbogo, should be easy for him.

okay,

five-foot, fourteen inches tall, two forty-five.
Suck up recoil like free tequila!

Ok Boyz!

The 550's are running on Frankensteins alpine twirler as we speak with photos this evening.

615 Grain .550" FN

Hybrid design between the .475" & .505".

You guys wanted them so here ya go!!!

tough and pretty... the Angelina Jolie of bullets

Woo-Woo!!!

At 615 grains that dog is going to hunt at about Mach III. 2500fps to as much as 2600fps to see how manly you are. Eased back to 2250 actual MV it should set the bar a little higher for manageable power in a DGR. I have been invited to bring the rifle and 30-40 rounds of ammunition at that speed to "demo days" at the SHOT Show. There is a chance that it will see production by a major US arms manufacturer the second half of 2008. Loaded rounds with Macifej's solids will sparkle in the light like deadly cylindrical diamonds.

I will have two weeks to get a good load and file in the standing rear sight once the bullets arrive.

hey.. what's the length??

1.37"

Are you taking a poll??

No..but, since i guess it isn't obvious, length is CRITICAL... in fact, one can't even plug into any reloading software without length, or guess consumed space, or understand changes to OAL..

to ME, diameter, length, shape, THEN weight are important in monometal bullets...

so, rather than querry for the length of the crimping grooves, I'll just moosey along

its a good looking bullet, and probably within a working weight for the 550 magnum, express or flanged.

Just messin' with ya El Jeffe Oso!

If you want to try some I'll send you the drawing so you can see if they'll work in your application. The diameter is .550" +/- 0.00000"

I love that the bullets are waaaay more precise than anyone can build a barrel much less rifle it!!

Beautiful. Perfect weight for a 550 Magnum and surely not too long at all for a 550 Magnum on the straight 460WBY case.

ISS will still have case capacity to spare with his monsters.

A .550 is the most tempting thing to me over .510 caliber.

I'll let you know if I ever succumb to the urge.
Excuse me now while I go self-flagellate to punish the idea out of my head.

55 lashes for 55-caliber Lust!

Ouch!
Ouch!
Ouch!
... only 52 more lashes with the Cat-O-Nine-Tails to go ...

Surely you have some tired peashooter in a overly diminutive bore which could be sacrificed at the alter of bore growth and consolidation!?!?!?

QL says
2250 in the 550 exp
2380 in the 550 mag
2213 in the 550 flanged
2521 in "my" 550 gibbs (high pressure 550 flanged, close enough for estimates)

6500 to 8500 ft-lbs

(can't run a QL without LENGTH .. and trust me, dozens of rounds are first "shot" within quickload before making the first case)

So what does QL say if you stuff one in the end of a 700NE Case?

"bullet is XX% smaller than bore" .. don't have it in my library.. LOL.. send me a 700ne case and i'll measure it!

Our freund Herr Horneber makes the 700-577 so maybe I'll have to strangle some of those down to .550"

700/577 NE would seem to be an appropriate plains game rifle for anyone who would hunt DG with a 2-bore.
Go for it Macifej!

It's getting a little crazy here, even for me!

It is really neat that this .550 Solid will work in all of the five-five-ohs here. Macifej is to be congratulated for his dedication to the project. Stop for a minute and look at what he has done for the wildcatters here the last half of 2007. All these neat solids.

Thank you...
