Do you mean the 375 Whelen? www.reloadbench.com/cartridges/w375whel.html 375 Whelen (375 Whelen Improved) Historical Notes: The 375 Whelen, also known as the 375-06, is another cartridge that was not developed by the late Col. Townsend Whelen, but was named in his honor. The cartridge was actually the work of the late gunsmith and writer L.R. "Bob" Wallack in 1951 and is based on the 30-06 case necked up. There are two versions, one based on the standard case and retaining the original 17 degree, 30 minute shoulder angle, the other Improved case with a 40 degree shoulder angle. The Improved case holds slightly more powder and and provides better headspace control, so it is the more popular version. The 375 inch caliber is as far as one can go in expanding the 30-06 case without running into headspace problems due to lack of a distinct shoulder. Experiments with larger diameter bullets have invariably led to headspace problems. An example of this was the 400 Whelen which never became popular and is no longer chambered. General Comments: The 375 Whelen is not as powerful as the 375 H&H Magnum or the 375 Weatherby Magnum but is nevertheless a good medium bore for most dangerous game. It is certainly adequate for any North American big game. It uses bullets from 200 to 3000 grains, and because it is strictly a handloading proposition, can be quite flexible. There is no reason why it can't be loaded down with 200 or 250 grain bullets for deer hunting as well as loaded to full power for larger animals. This is one advantage of wildcat cartridges; they must be handloaded and so can be tailored to fit different game and hunting situations. As with the 338 and 35 versions of the '06, Ackley's improved design is much superior. In this instance, it is mandatory to ensure adequate headspace control. +++++++++++++++++++++++++++ If I were you, I'd give serious thought about a 375Ruger. The gossip on one of the boards I read is good. It compares with the 375 H&H in terms of velocity. |
A .375 necked down to .30 would be a .300 win mag
|
I stand by my statement. Not arguing, but the .300 H&H is more like the .375 than the .300 WM. .338 Lapua is based on the .416 Rigby case. .300 RUM is based on the .404 Jeffries case. Neither has much in common with its parent. As for the cartridges you listed... .375 is a dangerous game round, the rest are not (.458 excepted!), and therefore I would rather have the more efficient, sharper shouldered, shorter WSM cases. 7MM WSM and .300 WSM in particular. |
Agreed...Just what in the world is the OP talking about?  Did ya know the 6.8 is based on the .30 Rem?

The 300 H&H introduced in 1925,the .375 H&H 1912! The .375 came first! Bob

The .375H&H was the first belted cartridge. . . It was originally loaded with ~61 grains of cordite. The .375H&H is a fine cartridge. I have no use for one, yet still want to get one |

I had a friend that said he wanted me to build him a tack driver in "375/30" I was assuming that the case was a .375 HH necked down to .30 Can't find any reamers for that set up and was wondering if you fellas knew of it ....or what. Thanks for the input....I'll keep digging. |
That would be a .300 H&H. Or you could "improve" it and have a .300 Weatherby. |
