Has anyone started to think about a 7mm or .308 with this cartridge? Buckfever

I've been leaning more towards a .35 cal

check out the drawing for the 8X68S magnum. Necked to 30 or 35 cal it's the 30 and 35 Newton, respectively.

I've been trying to come up with a cartridge theat will push a 160gr X 6.5 @ 2950 to 3000 ft/sec.Only interesred in shooting this bullet weight in the rifle.

Looked at shortening the RUM cases, would be a lot of work I think, I've never anneal necks before. I doubt if I need the full case length for the velocitys I want.

So I looked at the Dakotas and they would work quite well I think. I got a price on an action from a local gunsmith that can import them to Canada. OUCH!!! $3000.00 Cnd..

Onward

Now this new Ruger 375 looks to be just what the doctor ordered. It should run in anything that has a bolt face for any of the 375 H&H size rounds

Doesniper I have a 358STA that I hunt everything with( ok maybe not coyotes) just love the caliber. I'll bet by necking down the 375 Ruger it will come very close to the 358 Norma or maybe a bit better. It would be interesting to see what velocity you'd get.

Africa is on the, in the five year plan right now and this new 375 I think will be going with me. A little brother in a 6.5 would come along too.

What about a 264 Win mag? That ought to do it with a long barrel and some of the newer super slow powders. I have a reamer for a 6.5 STW, and it doesn't go any faster than a 264 mag, just uses more powder. I think the 264 is at or past the limit for a 6.5 bore. The 6.5-06 or 6.5-284 really is about as big as is practical, and either will almost do what you want if loaded properly.

The .308 and 7mm cartridges sound like they would be very close to the Dakota line of cartridges. I think that is a very good thing with Dakota Arms in receivership. wouldn't they be an easy rechamber of a 7mm Rem. Mag and 300 win. mag if you adopted compatible shoulder configurations. I think the 375 ruger case has a multitude of wildcatting possibilities.

Nobade if this is true on the length not making much of an impression on velocity maybe diameter will help. Any ways it not the speed I'm looking for, Hell I've got a 358 STA that pushes a 225gr @ 3300ft/sec and a 257 Weatherby. It's that 160 grainer a want to push at a reasonable velocity.

The case does have good wildcatting possibilities.

I am interested in the 7/375 Ruger.
Do you know if anyone has built one yet?
Thanks

mcwoodduck · « **Reply #9 on:** December 07, 2007, 02:38:46 PM »

What about going bigger? 405 (.411) or 416? with 400 grain bullets?

It definitely is possible to reduce the neck to one of much lesser bore diameter, but before doing it, I'd check the original neck length first. When a cases neck diameter is reduced so is the neck length, to greater or lesser degree. Reduction of bore diameter to .264 from .375 would substantially reduce the neck length to such that it might not hold the bullet under recoil. That is one of the major problems with the newer compact magnums for wildcatters. The original neck lengths are already at original bore diameter or less so any reduction in diameter further shortens the neck undesirably. A bore increase with these rounds have some merit due to lengthening the neck. This is beneficial due to holding the bullet under heavy recoil and to use different length bullets seated so that they are just shy of the lands upon closing the bolt. The best cases for bore reduction to a wildcat with the compact mags should be a factory round with a smaller bore diameter closest to the bore desired, and the next best would be using the next factory compact magnum with a bore larger that has the longest neck to begin with. A .375 Ruger to .423 or .416 is of interest as it would meet the ballisitcs of the .416 Taylor or original ballistics of the .404 Jeffrey. Both have good reputations in Africa on DG.

Bigger yet, 50/375 Ruger. 50 cal has been a popular Africa DG bullet for 100 years. But in the shorter ruger case, that would be interesting.

Cheese,
I don't have the dimensions of the new case. I have looked at one a friend shot at the shooting fair last year. I'm not sure you could get a .490 or .510 bullet in it and still have something to head space on. Unless your talking about blowing out the case as rebating the rim and more or less making a new case that shares a rim.
The .375 Ruger head spaces on the shoulder like most rim or beltless rounds. While everyone doesn't want a belt it makes head spacing easier on a strait walled cartridge.
Deltics,
Was that you sitting next to me on the wait bench in the mall holding a purse?

I'm not sure what you are in reference to. Unless you are in Alaska and have been in Prince William Sound within the last 2 months, it is unlikely you have met me anywhere. I refrain from mall shopping on general principle and have never carried a purse but have held my wife's while she is browsing near by. A .50 could be wildcatted from the Ruger but the shoulder would have to be steep and very short to headspace properly. A .416 or .423 would work good though.

Deltecs,
I did not mean to insult you, I was talking about the bench all of us guys end up sitting on out side some shop waiting. And yes I meant holding your wife's purse.
Again sorry if I insulted you. It was an attempt at humor.

mcwoodduck · « **Reply #16 on:** December 08, 2007, 10:31:04 AM »

Oops I also confused you with another guy that mentioned that he was taking his wife shopping on another post so now I'm really sorry.

No offense taken, just did not understand the comment and wished it clarified. I thought it was humor but could not for the life of me figure it out and thought I'd missed something, which at my age and health is not that all uncommon. No problem at all.

Thanks,
It's not age it's experience! I say every grey hair I have is from something cool I did.

i have been thinking the same thing of necking it down and up. Everything from 6.5mm to 458. cal. They should be just about like the STA and cartridges, maybe slightly lower powered. The ease of finding an action to convert or when making a change barrel rifle would be a beautiful thing.
