.366 D.G.W.
 

Any of you intrested in a cartridge that blows the Ultra stuff into the weeds, far flatter shooting and way more energy? If you are check this out!!!

250 grain bullet, 98 grains of IMR4350 = 3253 FPS and %875 FP energy.
100 yards = +2.35" velosity = 3046 Energy 5150
200 yards = +2.44" velosity = 2851 Energy 4512
300 yards = -1.74" velosity = 2664 Energy 3991
400 yards = -10.8" velosity = 2486 Energy 3430
500 yards = -25.5" velosity = 2313 Energy 2971

Yep that is the .366 D.G.W. a direct neck down of the .416 Rigby cartridge and just about the ideal bore diameter for that case to get the best efficiancy. You should see the ballistics with the 286 and 300 grain bullets. Think of it the .366 has more energy at 300 yards then the 300 Ultra has at the muzzle. and is flatter shooting. If you compair the trajectory and balistics to the Ultra Mags big brothers, you will see they fall even further behind. In fact the only cartridge that holds up at all to the .366 is the .378 Weatherby and again the .366 is flatter shooting. Its velosity may be alittle slower but the ballistic coeficiant of the bullets makes up for this and as far as flat shooting the .366 beats the .378.

I promised Jud I would post these pics for him,and if I don' t I just hate to see a grown man cry :DBesides that hes bedding two of my rifles this week and I don' t want him overcharging me like these Maine gunsmiths do [:' (]Just kidding Jud [&:]

RE: .366 D.G.W.
 

You forgot to post the recoil numbers. I can,t think of a thing in the world I would use it for. I would never own a rifle that I absolutly could not buy ammo for. If a 378 Weatherby won,t kill it it don,t need killed. Nice toy for a rich boy I quess. I would never need a rifle that had more energk at upteen hundred yards that a 300 Mag does at the muzzle. Not do I need anything as powerful as a 300 Mag. Sorry

RE: .366 D.G.W.
 

Where can I get one? I need a new varmint cartridge.:)

RE: .366 D.G.W.
 

Great pics! My keyboard has to dry now from the drool.

RE: .366 D.G.W.
 

As far as efficiency goes, the 366 DGW appears to do very well in that department. I too like to play around a bit with with cartridges that use mass quanities of powder. These are not as efficient but do have good ballistics.

30-378 WBY IMP
180gr Barnes X @3400 MV

100yds +2.3
200yds +2.6
300yds -.9
400yds -8.8
500yds -21.9
Does is shoot flat?


378 WBY
300 gr Barnes X @3000MV 5997 ft lbs

100yds +2.3 5330 ft lbs
200yds +1.8 4726 ft lbs
300yds -3.7 4176 ft lbs
400yds -15.1 3679 ft lbs
500yds -32.5 3229 ft lbs

416 WBY
400 gr Barnes X @ 2730MV 6477 ft lbs


100yds +2.3 5848 ft lbs
200yds +.6 5147 ft lbs
300yds -6.9 4515 ft lbs
400yds -21.4 3943 ft lbs
500yds -43.8 3431 ft lbs


All these numbers are moot if you cant hit where you are aiming. These big guns are not that easy to shoot accurately, especially in field situations. I would' nt hesitate on 300 yard shots with the last 2 alot further with the 30 cal. I think you' ll have to look hard to beat that 378WBY with a 300gr. Heck, out to 300 yards the 416 has good numbers, it will leave a bigger hole and penetrate very well, bullet drop is insignificant.
The .375 Barnes X has a BC of .555 and an SD of .305.
The .416 Barnes X has a BC of .546 and an SD of .330
The .308 Barnes X has a BC of .511

If I didnt already have the bases covered this 366 DGW shows merit.

yours in sport....AA

RE: .366 D.G.W.
 

Beautiful gun...But for kicks, I' ll stick to my .308 Norma Mag....shooting 180' s faster than you can imagine.....................................LOL:D: D:D

I have 2 guns now that I can' t find brass for............what would I want another for? LOL

RE: .366 D.G.W.
 

Pro-line, The last 308 Norma Mag brass I purchased was from Cabela' s I think. You might want to check them out, there prices are very competitive nowdays. As far as finding 416 Rigby brass, Norma has been doing good with that now, there was a time when it was very hard to come by. I do like the Federal factory stuff too.

RE: .366 D.G.W.
 

hmmm...I might have to stick with my .50 BMG for my hog hunting:D:p

RE: .366 D.G.W.
 

Recoil on the .366 D.G.W. in a 10 1/2 lb rifle is in the 50+ foot pound range, alittle less then the .416 Rigby. Not the chambering you want in a 7 pound rifle. With the brake design I used on my rifle recoil is more like a 300 Winchester but the recoil is slower and there is no muzzle jump even when shooting off the bench.
In the near future we hope to have the cartridge picked up by one of the factories as it is in Cartridges of The World, (tenth eddition) And the Safari Club International just did a feature article about it. If and when it gets comercialized all you non loaders can get ammo which if not into reloading is a real big handicap.
True it is not a cartridge for everyone, neither is a custom car, or for that matter anything offering ultimate performance. Things like the .366 only appeal to those that know the difference. To quote Mr. Walter Enslin, a professional hunter in South Africa and ranked as #4 in S.A. in their competive shooting circle.
" The combination of velosity and bullet weight of the .366 D.G.W. seemed more ideal then anything I have seen before."
Sorry James, this is somthing you will not understand!

RE: .366 D.G.W.
 

You will never know what I understand or not. Sorry ,you think to highly of yourself and not much of others.

RE: .366 D.G.W.
 

See, I told you guys he would never understand.

How this for a FLAT SHOOTING round:

This is my .270 B&B Mag:

130gr Nosler Ballistic Tip with 83gr (max load) IMR-7828 at muzzle = 3,863 fps/4,309 fpe

100yds: +3.10" ; 3,633 fps/3,811 fpe
200yds: +5.11" ; 3,410 fps/3,357 fpe
300yds: +4.22" ; 3,196 fps/2,949 fpe
400yds: 0.00" ; 2,989 fps/2,580 fpe
500yds: -7.95" ; 2,790 fps/2,248 fpe
600yds: -20.28" ; 2,598 fps/1,949 fpe
700yds: -37.60" ; 2,415 fps/1,684 fpe
800yds: -60.82" ; 2,241 fps/1,450 fpe
900yds: -90.65" ; 2,077 fps/1,246 fpe
1000yds: -128.97" ; 1,920 fps/1,064 fpe

Now that is FLAT! Not nearly as powerful in terms of FPE as the 366DGW, but plenty of flat. Savage Arms has looked at this round a year or so ago, in the aspect of making a proprietary (?) Savage round out of it. As of now it is still in the air.

RE: .366 D.G.W.
 

Geeze, 1SHOT...That' s flat!

They' re going to have to make a new line of scopes to accomodate that. Only 8" low at 500, with just 3" high at 100. Dang!!!!!!!!!!!!!!!!

RE: .366 D.G.W.
 

I think you will find your pressures are alittle on the high side. You might even be higher then the Remington Short Ultra nags, no that is not a mistake. Even so you run alot higher pressure then the .366 but it looks good. What length barrel are you running and what is it based on? Wildcats are alot of fun arn' t they, but James will never understand, will he? What is the trajectory if you sight in 2.35 inches high at 100 yards? I would be intrested in seeing this as several of my customers are into .270 diameter. You might try a different powder, IMR 7828 will jump your pressures in cold weather and I have found some other powders do just as well but do not have the variation of 7828. Sounds like a neat cartridge, and I am not a .277 fan. You might change that! By the way watch your bullet selection. Other then Barnes most .277 bullets are designed to expand at .270 Win velosity even the Weatherby is pushing bullet failure. You might think about Swift Bullets they hold up well.

By the way like little kids at school. YaYa My bullet hits harder then yours does!
Just kidding that .270 is an impressive round!!!

RE: .366 D.G.W.
 

1shot1kill:

What case is used for the .270 B&B Mag.?

RE: .366 D.G.W.
 

Judson, I am using a Shilen 26" barrel. The case is a highly modified .300 Win Mag case. I designed a .257 B&B Mag case first and had such outstanding results with the .257 B&B Mag round (4,020 FPS with a 100gr Nosler Ballistic tip and 75gr IMR-4831), that I used the same design for the .270 B&B Mag round. It has the shoulder blown out to minimal body taper, shoved way forward, with a shrp shoulder angle, and a minimal neck length. When I got back to the shop I checked my file on the .270 B&B Mag round and the 81gr load of IMR-7828 was my accuracy load at 3,698 FPS. I changed the load that I had listed at 3,863 FPS was my max load of 83gr of IMR-7828.

When I was working loads for the .270 B&B Mag, back in 1989, I tried H870 but could not get above 3,700 FPS even with heavy loads. I also tried Re-22 and IMR 4831, but got pressure signs before I could get above 3,700 FPS. IMR-7828 gave the the highest velocities and at 1/2" groups, more than enough accuracy for hunting deer. At the time I had a bunch of 130gr .277 Nosler Ballistic tips on the shelf, so I started with working them. They shot so well, I stuck with them. Since this is mainly a long range bean field rifle, used only for deer here in NC, I have stuck with them. So far the 130gr Nosler Ball-tips have proven extremely effective on the deer here in NC. I have also taken a 372 pound black bear with this same load. The shot was about 90yds, the bullet did not past completely thru, but the bear dropped in it' s tracks.

As for the pressure jumps in cold weather with IMR 7828, I have not noticed any signs of excessive pressure in cold weather. I guess that is due to the fact that it does not get that could down here in NC. A cold day down here, late in the season around late December, temps can get down in the mid to pow 20' s at night. These loads were worked up in cold weather, in February and March, and they are not showing any signs. Brass life has been good, as I am still shooting the initial lot of brass I worked up back in 1989. Of the initial 100 cases I started with, I ended up with 88 after the fire forming. Over the years I either lost some cases, scraped some due to split necks, etc., as I am down to 64 cases now. I have never had a head separation, blown primer, or swelled primer pockets.

I have toyed with the idea of trying a couple of new powders, Barnes X bullets, and maybe the Swifts or LRB Technologies J36 bullets. But I hate to to start toying and messing around with a combination that works so well. It' s kind of like a, " if it ain' t broke, don' t fix it" type thing.

I try and post a picture of these case if I can in the near future.

RE: .366 D.G.W.
 

Thanks for the info. I am not a .277 fan but is because of yoyos up here who rave about the .270 Win being the best thing in the world since sliced bread. Acording to them nothing else is close. BUT we are not talking about the Winchester are we. If sighted in at 2.35" at 100 what is the trajectory? That is what the computer program gave for the .366 if I wanted a 6" point blank range with a 250 grain bullet. One of my customers had me build a 6.5/8mm Mag. really impressive but very, very bad for the meat hunter, real big mess. He shot a deer in the front shoulders and said the meat was blood shot up into the neck.
You must run into the same thing unless you use bullets such as Swift or Barnes.
A few questions, do you need forming dies and what do you use as a firing forming load? One more question. Is your father Willis Ball? If so PLEASE thank him for the excellant article he wrote about the .366 D.G.W. Give me a call, lets talk some time.

Heres you cartridge and gun pics Jud -






































I' ll let you explain the pics and what cartridges they are.

RE: .366 D.G.W.
 

Thank you Woodseys!!!
1. My .366 Dgw based on an Enfield action and L to R, .308 Win. .366DGW, and the .416 Rigby, All fine deer cartridges.

2..366 DGW The .416 Rigby and the .505 Gibbs

3. The .366DGW and its parent cartridge the .416 Rigby

4.Various loads for the .366 DGW L to R 250 grain Nosler Ballistic tip, the 270 grain Speer, Barnes 286 grain solid and the Swift 300 grain A Frame, this is what I used in Africa.

5. .308, 3006. .366, and Rigby

6. My rifle in Africa, this picture shows the brake rather will. Picture 7 shows another view of the rifle.

RE: .366 D.G.W.
 

Again, thanks Woodseye!!!

1. My P-14 chambered for the .366DGW and Lto R .308, .366, and .416 Rigby. All fine deer hunting rounds!!!

2 the .366 the .416 which is the parent cartridge and the .505 Gibbs, That 505 kind of makes the .366 look rather insignificant.

3. .366DGW and the .416 Rigby

4. The loads I tested for the DGW Nosler 250 grain Ballistic Tip, 270 grain Speer, 286 grain Barnes solid, And the 300 grain Swift A Frame which is what I used in Africa.

5. .308, 3006 366, and .416

6. My P-14 in Africa you can see the brake rather will in this picture, the last picture shows another angle, Enfields do not have to be ugly.
