info on 9.3mm
Hasse-91,
Can you provide a bit of info on the field effects with your 9.3mm rifle?
I think I can see where you are coming from now. There are some really serious 375 boomers, and your std. mag., which ever case you use, will barely make the cut. You will be using bullets which will work through the 378 Wea. and 375 RUM. You may get bullets penciling right through. The 9.3's don't have the jumbo boomers, so how do those heavy bullets expand in thin skinned game in your neck of the woods?
I respect you wanting to stay with the .375 Taylor, but the 416 Taylor or any of the wildcats made from the H&H or Ruger parent cases, will handle the Speer 350 Mag Tip, loaded down to 2400 fps., and this bullet was made for Arctic Game. 2400 is about the maximum penetration velocity. 2550 will slap you around a lot more.

You won't notice much difference in 358 Norma and 375 Taylor, except 375 will kick harder if you load a heavier bullet. You're not going to get a softer recoil unless you load to less velocity, which is entirely possible. I've used the 285 gr. Speer, it's a very good bullet and will hold up well even at close range. If you wanted to load a 270gr. or 285gr. to 2400 fps. recoil velocity would be decreased and you would still have very good killing power. Of course then you wouldn't gain much over your 9.3x62. I hope that if you get a 375 Taylor that you keep your 9.3. You just might decide to go back to it.
The belt is not a problem if you set up your dies to headspace off of the shoulder.

I did some research into the 375 Whelen recently because I was thinking of rebarrelling my Ruger M-77 30-06 to something with a bigger bore. Basically, it's a 375 cal version of the 35 which allows you to shoot fatter & heavier bullets at the same speed as the 35. Another thing I like about the 375 Whelen is 30-06 brass is VERY EASY to find in the USA and it won't kick as much as the "bigger" 375's. arkypete has his rifle set up for shooting cast bullets only. Hard cast bullets work quite well for killing big things like moose because they don't deform or deflect as much when they hit bone. PM arkypete for more details. He's very happy to share his knowledge

The 9,3x62 has a smoth recoil, good death no matter what bullet you choose. Personal i have been using the Sako Hammerhead 286gr and i had in mind to use the Barnes TTSX 250gr or TSX 286gr this moose and bear hunt but i didnīt have monney. The bullets expand with no problems in even deers or foxes. Accubond and Barnes works just fine. I wouldnīpersonal use soft points on small games, you have to run with a plastic bag and catch meetballs falling from the sky. Itīs quite close to the 35 Whelen. I think the 9,3 is a good caliber, no matter of what. But i tough the 375C-T maby has even smother recoil, and i personal like big and heavy bullets flying threw the air. I have problems with calibers from 7mm up to beneth 9,3mm. I really canīt handle the rappid recoil without a silencer.
I have been looking at the 375 Ruger and i canīt find annything wrong with it. Itīs just that i like the magnum belt. But it will maby be even sheaper and easier to take the Ruger. Iīm gonna get a 458WinMag as well. Thatīs why i want something in the middle (375) that will work alittle better at range.

The 30-06 is the most popular here in sweden. 8x57, 9,3x62/57, 30-06 and 6,5x55 Swedish Mauser has been the most popular cartridges for years. The 308, 338, 358 and so on is getting here to. But most of the hunters was born with the most common cartridge and itīs there they stand. I doesnīt think the 375 whelen would be something for me. Then i just would keep on to my 9,3x62.

Yes, I get that. Your 9.3x62 is already more power than a 375 Whelen would be. Good luck finding a rifle that will "scratch your itch".

If you hit bones and use a soft point it will almost blow up. I saw a deer that had been shot with Hornady InterLock 286gr, my fist went right into the guts on the backside where the bullet came out. So i recomend a hard bullet for smaller games. But in moose the soft point bullets is really good! But i prefer Barnes TSX or TTSX now.

Just for fun...
Just to toot my own little horn a little bit, here's my wildcat, Hasse. The 300 Nevada Desert Magnum (300NDM) has the same case length, the same neck length and the same shoulder angle as the venerable .30-06 Springfield. Long neck keeps flame and heat inside the case, minimizing throat erosion. Gentle shoulder angle makes it feed well. No belt to bugger-up the feeding. Cost was around $3000 for various dies, reamer, machining, new barrel, travel to gunsmith, trimmers, et cetera. Not especially cheap, but quite intrinsically rewarding. Now working on necking it out to .358-caliber...
Case volume of 300NDM is 23% more than .30-06 and 10% less than 300WinMag. Kind o' the perfect "middle magnum," if you will. Chronographed 3000 fps using 68 grains of H4831SC under the 180-grain Sierra MatchKing. Has shown best promises of being good on pressure when using 70 grains of H1000 and 150-grain Hornady FMJs. No chrono values for that load, however. Hart barrel puts 'em in the same hole with pleasing regularity...
Visual comparison above is from ammoguide.com, a great site with tonnes of info for so little per year. It's basically a "reloading manual that never needs a new edition to be printed" because the members always keep it updated with new loads, et cetera. Y'otta sign up. Cheap, too, at less than five cents per day (I think) for all that's there. Might be less, but still a whoppin' bargain any way you slice it...

What was the parent case? From the diagram you attached, it looks like it would have more than enough shoulder if blown out to 375 and give Hasse what he wants. Just a thought...

Hasse-91's new idea
Hi Hasse,
Maybe you have a new product idea here. "Soft Point GAME BAGGIES"!

Well, we were going boldly where no man had gone before. And I am single with no dependents and no debts. Makes life easy and fun...
This is a de novo round, meaning "of the new." Nothing else like it on the planet. It's just a .30-06 Springsteen on a magnum case. Simple. Makes me wonder why no one ever tried it before. Just as Colonel Townsend Whelen developed the 35 Whelen by just necking-out the Springsteen, this round is simple in design, too. But people seem to want to have their dental fillings shaken out by a "big" magnum-- the 300 WinMag or 300RUM, for example. Not me. I also want to delay paying for a new barrel. Shooting a hot magnum costs about a buck a shot in replacement costs for the barrel. That short neck costs a lot of money, in case you didn't know it. Maybe I should say "that big powder charge to get that light-speed muzzle velocity" costs a lot of money. In contrast, my round keeps all that heat and flame in the neck, and saves the throat.
Parent case is the 375 Ruger Basic, Hornady p/n 8674. Case is .510 inches (12.95mm) in diameter at shoulder; .530 inches (13.46mm) at the head. 1:167 taper rate ( very cylindrical) keeps the bolt thrust down. By contrast, the .30-06 (a combat round) has a taper rate of 1:110 for easier breaching and extraction. Volume/capacity to the bottom of the neck of the 300NDM is 76.8 grains of water; about 86 or so to the mouth. I don't measure to the mouth because the bullet precludes having powder there. Why bother with such a figure if it can't be used for powder? I have empirically measured the 300 WinMag to have 87.2 grains of water capacity to the bottom of the neck, and the 300RUM to hold 105.5 grains to the same location.
The cost was in having Hornady make up forming dies and reloading dies; in having Dave Manson machine a reamer and headspace gauges; in having Lee Precision make up a Factory Crimp Die; in having Lee Precision machine up trimming mandrels of specific and graduated diameters; in 300 raw cases at about a buck each; a new Hart barrel in stainless at 510 bucks; new Shrewd Number Four muzzle brake at 75 bucks (mailed); travel to gunsmith (600 miles or 966 kilometers); petrol at about $4.00 a gallon (Summer 2012) and the reaming my gunsmith gave my wallet. Took me from July 25, 2008 (first day of design work) until July 15, 2012 to fire the first round at approx 1500 PDT, about 15 miles (24 kilometers) south of Winnemucca, NV. But it was worth it. What a feeling! Now, when I fire the rifle, I "feel" everything that went into it. It's MY creation. Nobody else has one. And now, a .358-caliber version is on the way. We'll just follow Colonel Whelen's advice and neck out the 300 to fit the larger bullet...

I'll draw one...

I'll draw one using the parameters we have, and we'll get a look at it. Will post it up in a few minutes...
Here it is:
What's cool is that you can take just this drawing and have forming dies and reamers, et cetera, made to actually go forward with the cartridge. That's how I did it. All Ben Syring (custom die designer) at Hornady and Dave Manson at Dave Manson Precision Reamers need is the outside dimensions of the thing, and they can design from there. Easy. Just takes time and money. And patience. Lots of that...
YIKES!! I have made a mistake. In order to use the same FD1 and FD2 forming dies already on file for the 300NDM at Hornady and the same headspace gauges already on file for that same mildcat at Dave Manson, the height to the top of the body has to be 1.832 inches (46.533mm)-- not what is shown in the picture. I should have designed from the head, not from the top of the neck. I used a 1.25X-of-caliber neck length-- same as on the .30-06 Springbok. The height to the top of the shoulder should be 2.005 inches (50.93mm). I should have designed to the top of the body and let the neck length float to whatever value it became. The difference would be quite small-- something like .021 inches (0.533mm) longer. Correct dimensions would be to have the top of the cylindrical body at 1.832 inches (46.533mm), the bottom of the neck at 2.005 inches (50.927mm) and the total case length at 2.473 inches (62.814mm) to maintain the .30-06 SpringerSpaniel's 1.25X-of-caliber neck length, making it just a red hair shorter than the .30-06 round. If we wanted to let the neck length float in order to keep the 1.832" measurement to the top of the cylindrical body and maintain the 17.25-degree shoulder angle that is formed by the existing forming dies, the neck would come out to be .489 inches (12.421mm) long. Not a tonne to worry about, but it should be on the picture correctly if we are to be called professionals. At what, I do not know. But that's not my department...
Cartridge Creator was used to draw the above and is from ammoguide.com, a great site with tonnes of info for so little per year. It's basically a "reloading manual that never needs a new edition to be printed" because the members always keep it updated with new loads, et cetera. Y'otta sign up.

Hasse's reamer...
WOW!! Too big at 1000 pixels wide. Will size it down right away and re-post...
Well, sized it down to 800 pixels wide, and it looks like krapp! The lines are all mottled, broken up and show traces of red, green and blue color in them. Looks really bad. Will just send 1000 pix example to Hasse via PM. He might enjoy getting an eyeball on it...

Iīm not single so the monney doesnīt last for long... Would be interesting to know how much it would cost me to create custom dies and reamer and ship it to sweden. A new barrel fited to a gun would cost about 920 USD, Lothar Walter. And ofc petrol for about 200km.
