600 Overkill
Big Bore guys are the best
Hats off to CCMDoc beer. This very nice gentleman was kind enough to send me several of the beautifull brass flat nose solids on the right below for me to test. Paul dropped me a line offering them for no charge (he even shipped them to me at his expense) if I wanted to test them in my 600 overkill. I believe he got these from Mac and the quality must be seen to be understood. They are a work of art. I will test then in some penetration tests soon and report back thumb

Agreed! CCMDoc is one heckuva man. He let me shoot up about thirty rounds out of his 600OK last summer in Helena. With AHR's brake it was a nice shooting rifle, and very accurate.

Doc, you are Da Man!

I have gotten far more from the people on this board than could ever be repaid. Sharing the fun is the fun - that people post on this forum is proof.
Thanks for the kudos and thanks for everything.

Stay well and let me know how those babies shoot! I have no doubt they will be awesome, just haven't gotten around to trying them myself.

600 Overkill
Let's talk a little here about the bullets. If my pictures where clearer you could see some really cool features of them. The driving bands are tapered which will allow a great crimping feature as well as an excellent design as a compression bad in the barrel. The bases are slightly beveled as on a boat tail which will help in loading. The nose and bases are parted off very clean. They just look great. One question I have is why brass? Why not bronze? Does brass rivet less on impact? Just curious. I think I will drive these to around 2200-2300 FPS and think they should penetrate phenominally.

Here is a couple pics of a retrieved bullet from test media. I'd say the bullet did very well. Bullet is one of Mac's and is a .505" 558 grain hammer that left the muzzle at about 2,250 FPS with a 1 in 10 twist barrel, penetration was a straight line. Same set-up in .458 Lott Hornady 500 grain FMJ with 1 in 14 twist penetration was about an inch less and swayed off course in same media.

The test media- a stack of very tightly packed, dry, unread magazines. Figured these would do for some simple testing at the house. Although there is nothing in there to simulate bones or the varied degrees of animal tissue, this gave me something to use to compare with other bullet/rifle combos. Penetration was about 13"s with the .505 Gibbs at 2,250 FPS, 12"s with .458 Lott and about 2 3/4" with .44 Rem Mag.





Hope these were some help showing how the bullet performed. Rodney.

Speaking of big bore guys are the best, this all started with a sample bag of bullets from Mac at the Houston "Hoot-n-Shoot" last year. Thanks Jay, the bullets perform very well. Rodney.

You might ask Macfez, but it may be economics. Bronze is much more expensive than brass.

Rodney,which is the bullet you shot from the Lott? FMJ? What brand? Is it the one on the right,in the picture?

Shootaway, the bullets pictured are from the .505 Gibbs and are our very owns Macifej's FNs, an unfired to compare to the fired one. The .458 Lott was a Hornady factory loaded Full Metal Jacket round nose, I figure these were good to compare with as the velocities were about the same. Don't know what I did with the .458 bullet, but it did not perform as well, although both would most likely do the job. Got to say that the .505 Gibbs with the 1 in 10 barrel and Mac's bullets are a great combination as it just drills the bullets through most anything. Rodney.

Pretty impressive performance from the Lott.Nearly WHOOPED the Gibbs using a cheap Solid!

Rodney - glad to do it and hopefully I'll be able to make it to the shoot this year. Those are some pretty tough magazines but I think you'll find the penetration increasing with velocity. A little hotter load might yield a big increase in penetration.

Brass over Bronze ..?? Brass obturates at lower pressure, has a lower COF, machines better, is heavier, and it is usually somewhat less expensive. The major cost component for us is machine run time not material.

There are hundreds of brass and bronze alloys. I think we have arrived at the optimum balance with the one we're using. However, we can easily increase bullet toughness by switching alloys if someone has the need. At some point the bullet becomes tougher than the barrel. Field reports on the significantly softer Copper alloy we use show it to penetrate 1/4" steel plate with ease from a Double Rifle in .577". That should be enough for Mr. Buffalo ... Wink
