I bought a Gibbs 505 CZ and it shoots great and groups 1" at 100 yds with barnes 525 gr tsx that I tested this weekend. But only takes 3 rounds in mag and nothing in chamber as far as I can figure out. Anybody had a 5 round magazine made and is it worth it for buff? My extended mags on other rifles tend to get in the way.

I am considering getting mine modified to close over a chambered round so it is 3 + 1. I think it would be difficult to get 4 or 5 down without making the rifle look ugly. An experienced gunsmith may be able to give you a more qualified opinion though.

Be careful, if it feeds and functions flawlessly now I wouldn't chance it. If three from a 505 Gibbs doesn't do it, then four won't either.

Jim Wisner made some pocket floor plates that add just enough to close the bolt over 3 rounds. It may need a little shaving off the follower too, but as long as you keep the contour correct that's not a big deal.

OTOH, this topic always reminds me of Mike's axiom #4:

4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified so it can carry at least 5 down.

Interesting thought on feeding performance over more rounds. I think a 4 down single stack 505 would be sweet. Have the floor plate even with the bottom o the trigger guard.

Most 505s kick enough that with recovery from recoil + cycling the bolt, it will be very hard to get three much less four or five well aimed shots off over the span of a hard charge.

Actually if you can get two away over the timespan of a charge you would be doing well. Where I want the extra round is when you stalk up to a mob of pigs, once you empty your mag and have to reload the survivors usually get away, so one extra round before you have to reload will help the tally. (keep in mind that farmers who allow you onto their properties to shoot, like you to kill as many of the pigs that you find as is possible.)

If you are shooting pigs only, down load it a bit as the recoil from full loads means less time to reload, more time for pigs to get away.

Also, learn to single feed into the Magazine quickly, both standing still and on the run
and top it up at every opportunity.

Also, see if you can get 3 in the mag and then load one into the chamber.

That one extra cartridge can help.


The above is based on experience although
mine is with a Magnum Mauser.

good point!
Last time I had the 505 out after pigs we came across a mob of 8. I got 3, by the time I got an extra round loaded the last pig that scattered in my direction dissappeared into the brigalow. Last trip I was using a 30/06 ruger (5 down + 1 up the spout). That time I got 5 for 7 shots, missed once, had to shoot one twice, so same thing, I only had time to grab one extra round and load it, but the extra magazine capacity certainly made a difference, (and probably the minimal recoil too). The other option I have which does not involve modifying the rifle (and Chuck375 made a good point, ... why mess with something that feeds flawlessly), and that is to feed one in from the top of the magazine, apply the safety, then turn the rifle over and open up the magazine floorplate and load one extra in from the bottom, then close it again and away you go with 3 down + 1 up the spout.

My 505 Gibbs got 7 pigs with one shot !!!

The guy who owned it came across them feeding,
they all walked out and got on a bank in a row
so he put a solid through the lot of them !!!

The other thing the guy does is wait for two pigs to run together or cross and shoots both with the one shot. It pisses me off as it means less for me to shoot !!! LOL

Anyway, I think you have sorted out your problem now, plenty of other ways to do it than stuffing around with the mag.

Sounds like great sport! I know you can't have a semi-auto so AR15 discussions are moot. My pig guns have evolved over the years from 270 to 220 Swift, on to 223 and now 458 SOCOM. I have an AR in that caliber but I just built this integrally suppressed Remington EtronX electrically primed 458 SOCOM:





I wish there was an easily convertable 50 cal but .458 was the best I could find for the platform. It will hold 4 down.

Only 7. Is there anyone who shot 8 or more?

Hmmm... 5 in line was my best with a 270 Win (three times in 4 years), two of the five were usually a surprise after the shot. We were night hunting over feeders. Seven is admirable! Maybe a world record with a center fire rifle.

I reckon someone with a purpose - and probably a feeder - could line up more than 7 in one shot.

Just look at some of the photos that are posted of mobs of pigs at feeders in Texas and other states.

All it takes would be instead of using a feeder,
use the feeder to get in big mobs then one night, tip a line of feed in a straight line
and you'll get them all lined up.


The only reason these 7 lined up is they came off a flood plain and all stood on the channel bank type thing.

Probably more luck than anything else.

Awesome, I am going to have to try that one day. The trick is getting them to stand in line!! I am sure I can line up a feeder, or even just a row of corn.

Please explain. I don't know what that is, but it definitely sounds interesting! Does that mean your primers are touched of with an electric charge, ie no firing pin, very fast lock time ??

Yes, the system is the same in operation as the military weapons that fire electronically. The firing pin is a probe that rests against the center of the primer. That part of the primer is insulated from the rest of the cartridge and when you pull the trigger you are sending a fire command to the motherboard in the butt stock. The computer checks the parameters of the chambered round and if all is in order, it sends an impulse to the primer. It all takes 27 micro seconds to execute. Remington made these rifles in 220 Swift, 22-250 and 243 for a few years. They were hoping the short locktime would be a selling point but it was an answer to a problem no one cared about. Reloading is the same except primers are pretty pricey at 200-225 per thousand. I rebarreled mine and suppressed it because the action is silent; no moving parts until you cycle the bolt. Other than the fire control system it looks and operates like any other Model 700.

I bought a reasonable supply of primers early on and I think I'm covered until I can't shoot anymore. If I run out, the rifle can be converted to conventional use with a replacement bolt and trigger.

Very Interesting, Thanks for the detailed explanation.

Great thanks for the input. I have a 375/408 / Gibbs 505 rifle with 3,5,and 10 round magazines but I find I rarely use the free mags but it seemed it would be good to have 4 rounds or 4+1 otherwise the is little difference to a double when it comes to shooting rate

This is my .505 SRE rifle, built on a P-14 Enfield action, three down and one in the chamber. It shoots a 570 grain bullet at 2150 fps., same as a .500 NE, and weighs 8 3/4 pounds.



This is a buffalo I put four rounds in as it ran past me at about 30 yards, three close enough to cover with a playing card.

My experience with shooting heavy recoil rifles is that not only did I not notice the recoil while shooting at dangerous game, there was very little muzzle jump to cope with. I think it has to do with the body not being braced to resist the recoil. I was perched on a four inch wide ledge while the action was gonig on, and although my gunbearer was standing behind me in case I toppled off from the recoil, I did not need his assistance.



On an earlier hunt, I used the same rifle to put down an elephant with a behind the ear brain shot. I was perched on top of a termite mound at the time, and fired two shots in rapid succession, again without losing my balance, one into the brain and another into the heart.

My wildcat .505 is based on a .460 Weatherby case and is not as large in diameter as a Gibbs, but I think three down and one up the spout is a useful arrangement.

So cool!

Great buffalo. Why did you not just take a 460wby and neck it up to a 505 and rebarrel?

The .460 Weatherby case is unnecessarily large to duplicate .500 NE velocity with a 570 grain bullet, plus I wanted a cartridge which would fit in a .30-'06 length magazine, plus I don't have a high regard for Weatherby rifles.

My load of 90 grains of IMR 4064 filled the case right up to the base of the bullet and the Enfield action is unbelievably slick.

My little wildcat, the center cartridge in the photo above, was sufficient to take three elephants and five Cape buffalo, and a black rhino (this was 1971, when rhino were plentiful and legal).

My 500 Jeff holds 3 down, I've never tried to put one in the tube at the same time. I know Duane makes bottom metal to take another round. It just took so much pain to make it feed and extract perfectly I'm not willing to mess with it!

Thanks xausa and chuck for input.

It possible to have a custom floor plate made that will add an additional round. Not real tough to do. Depends on the action but doesn't look bad compared to a "coffin Mag".-Rob
