I hade my Searcy 450 NE converted to a Talley based rib. Now I can add either the Leupy 1.5X5 or the red dot. My eye are starting to get tired so this helps.
Looks don't count as much as being functional.
Did you make a die to size the cast bullets?

Hello 500Nitro,
Yes, I have no problem with irons sites also, even up to 125 yds. But, Our deer season starts at 6:30 am in the morning. However, I can't see the irons until about 7:00 am. That's why the scout-scope is a nice touch. I used it from 6:30 am until 7:00 am, and then removed it and put it in my pocket. I put it back on for the last 30 minutes in the evening. Same reason, too little light to see irons.

Hello AkMike,
I think it looks "cool" with the scout-scope set-up. I wish my Leupold was a 1.5 ... 4x is a bit too much. Wanna trade?
I didn't size the bullets. I used them as purchased in .510 dia. They work just fine. At these low velocities (low pressures) that I'm loading, they just "squeeze" down in the throat.

Nah,, I like my set up! 
No need to change but it might give you some additional ideas. If you decide to go the 1.5 route have a look at the illuminated ones. That little red dot will help with dawn and dusk shooting.
Mine isn't an EER scope.

The first thing I shot with my 505 Gibbs, we saw it from the vehicle as we were driving to Spotlight foxes / cats (and other things !!!), he pulled up, I jumped out, grabbed the gun off the back seat, loaded it and stood under the spotlight so I could see the sights and at the same time as highlighting the animal in the light !!!
It lifted said animal off the ground and slammed it into the deck as well as putting a spray out the back that was pretty impressive in the light !!!

Hello 500Nitro,
I bought this rifle on Thursday evening, and our 9-day hunting season started on Saturday. So- too little time, and too much to kill....
buckstix
Looks like the "Scout-Scope" feature for my 505 Gibbs works just fine. I love it when a newly acquired rifle, draws blood the same year.
The deer came out of the pines about 70 yards distant. He was standing in knee-high grass and faced straight at me. When I shot, the recoil set me back a bit, and when I regained my balance, he had totally "vanished" from sight. I never saw which way he ran. I approached to where I last saw him, and started looking for a blood trail.
And there he was. When hit, the deer dropped with all four legs still under him. He never knew what hit him.
My diary reads, "2013 season. Hunting with newly purchased Brevex 505 Gibbs "Scout" Safari rifle. Success at 7:30 a.m. this morning, from about 70 yards, - a standing front-on shot, 6" below the throat. Bullet went through the neck, across the top of the chest cavity, and lodged into the spine. Dropped like a stone. Big deer, small rack".

IMHO that picture would have looked much better if that fork horn was taken with the 20/577! Now that would be a classy picture.

Hello AkMike,
Well, I now know why African Hunters using Big Bore Double rifles, have Gun Bearers. WOW! My 20-577 Dixon Double really got heavy lugging it around. Unfortunately no luck bagging a deer with it. But I did enjoy using my 505 Gibbs for the task.
I've had a lot of emails asking why and how I'm using .510 - .511 bullets in my .505 Gibbs.
Here is a neat little trick. I start with some Cast Performance 350g gas check bullets. They run about $45 per 100. That's a heck of a lot cheaper than most bullets for the 505 Gibbs which retails for $1.50 to $2.00 each.
I use a .458 sizing die (with the decapping stem removed) to resize the body of the bullets. It actually "taper-sizes" them.
I made a small pusher plug that controls how far into the die the bullet is pushed. The deeper into the die you push the bullet, the smaller its gets. I only go to the depth of the top of the belt which is approximately .510" dia. on the gas check, smaller farther toward the point. I finger lube the bullets with ordinary sizing lube.
To remove the bullets from the die, I push them back out the bottom of the die with a small brass rod. since the die is tapered, a small tap frees them and they drop right out.
Here are the two brass rods. I used my lathe and made them a little fancier than actually required. The two bullets shown have been resized. Gas check is still .510 dia, but the band at the middle is .505 dia., with the front band a little smaller in dia.
The loaded cartridges have a good overall length and feed nicely through the action's magazine, even though these bullets have a pretty flat nose.
Since I'm only using 54g of IMR4198, there is a lot of air space in the case. I use a method from Smokeless for Black loading. I cut pieces of 5/8" dia. Foam Backing Rod (available at any hardware store) to lengths of 1.9" to fill the air gap and keep the powder against the F215 primer. Since the case mouth is only .505 dia. and the backing rod is .625 dia., I finger lube the outside of the foam rod ever-so-slightly and "screw" it into the case while gently compressing it with my fingers, being careful not to squeeze it too much or the cells of the foam will break and it won't spring back to full dia. The 1.9" long foam rod weighs only 1.9 grains. Its under slight compression and keeps the powder in place, even in those cases in the magazine which are subject to the rifle's recoil.
My chronographed muzzle velocity of 5 cartridges was 1680 fps, perfect for dangerous Wisconsin whitetail deer.

Hello all,
With a break in the sub-zero days here in Wisconsin, I did a little more load testing with some reduced loads.
I found very little reloading info when searching the internet forums for reduced loads. These were the only ones I located.
The following loads were found on the internet.
THESE ARE NOT TESTED - USE THEM AT YOUR OWN RISK
bullet ---------- powder in grains --------- velocity
525 ------------- 90.0 IMR 4064 ------------ 1750
600 ------------- 50.0 AA 5744 ------------- 1450
600 ------------- 55.0 AA 5744 ------------- 1540
680 ------------- 45.0 AA 5744 ------------- 1350
I also emailed Accurate Powders and asked them for load data for 505 Gibbs using 5744 powder.
This is what they sent me. THESE ARE NOT TESTED
bullet ---------- powder in grains --------- velocity
535 ------------- 55.0 AA 5744 ------------- 1600
535 ------------- 62.5 AA 5744 ------------- 1800
535 ------------- 70.0 AA 5744 ------------- 1900
600 ------------- 52.0 AA 5744 ------------- 1525
600 ------------- 58.5 AA 5744 ------------- 1650
680 ------------- 65.0 AA 5744 ------------- 1800
The following loads were tested in my rifle - 21" barrel.
bullet ---------- powder in grains --------- velocity
350 ------------- 55.0 IMR 4198 ------------ 1630 (short case)
350 ------------- 55.0 IMR 4198 ------------ 1590
525 ------------- 56.0 AA 4744 ------------- 1500
525 ------------- 60.0 AA 5744 ------------- 1600
With the weather so cold, I didn't do my best for groups, but did get an idea of what to try next.

Hello 500Nitro,
It's mostly me. Temperature was about 15 degrees. I was shooting off my elbows, on the bench, ever-so-slightly touching the back of my hand, on the front rest to help steady the rifle. With only a 2X Leuplod scope, it was difficult to get a real "fine" sight picture, especially while shivering. I was mostly interested in measuring the velocity before I loaded a bunch of ammo.

LOL, He might not understand the shiver factor as well as the rest of us in the beginning of winter.

Yes, I hadn't thought of the Shiver factor !!!
I have the opposite, the drip factor from sweat.

Hello 500Nitro,
I also have the drip factor but its age - not gun related.
All in all I'm not dissatisfied with a 2" group at 50 yards. I'm sure in the summer I'll be able to do a lot better. I also intend to set-up a higher power variable scout scope for load development. That's the nice thing about Warne QD lever-rings, they make for easy on/off, and they are very repeatable. I have them on several rifles and have experienced 1/4 MOA repeatability.

LOL, try doing some shooting at these temps! -59 Celcius
Not that I would! But it could happen.

Holy shit! Forget about shivering; at -59 Celcius my balls and everything else would fall off. I can see the recoil of the just about any rifle shattering me to bits like a piece of cheap China ... no doubt pleasing a polar bear with its newly found pile of bite size pieces.

Hello All,
My research continues. I've contacted Magnum Magazine, a South African publication, and ordered 6 of their back issues; July 94, Oct 95, May 07, Dec 07, Feb 08, Sept 08. These contain articles written by PH Carl Labuschagne.
I'm not sure about the subject mater of the articles, but I'm hoping that one of these will give the details of building this rifle.
I'll update when I receive the magazines.

Wow AKMike, there's more than the difference between water freezing and boiling between us. It's 47c here. That's 106c between us, if I did that basic maths right.

Well, I got the first of the "Magnum" magazine back issues that I have on order. Magnum is a magazine published in South Africa. This one is the July 1994 issue. There is a very interesting detailed article written by Carl Labuschagne entitled; "Make Mine a Turnbolt" where he discusses his Professional Hunter preference for a bolt action rifle, rather than a double rifle, for Dangerous Game.
I also found another reference to Carl Labuschagne in a book called; "The Greatest Quotes from Sporting Literature" by Chuck Wechsler & Jim Casada.
This book is full of famous quotes by famous men. Neatly tucked between the quotes from Henry David Thoreau, and Rudyard Kipling, was Carl Labuschagne's quote. .... {b}"Make Mine a Turnbolt"[/b} and the book references the July 1994 issue of Magnum Magazine as the source.
I have 5 other back-issues of this magazine coming. I'm hoping to get more insight into the man, and my rifle.
