Home Forums Hunting & Shooting Custom Rifles & Wildcats 7mm-375 Ruger?

I've thought of putting together a BIG 7 for some time. This cartridge seems as though it would work well. It would fall between the STW and RUM in case capacity, although it would seem to be better balanced with a shorter, more efficiently burning powder column. Any thoughts?

True there is interest in a 7mm-375 Ruger. Are you planning a wildcat or waiting for a factory round?

For myself I have no interest in another wildcat. Been there done that.

The 7mm WSM is hardly mainstream but its here for now. One on a long action would work until something happens factory wise if ever. Then if a 7mm-375 Ruger gets introduced your barrel could be rechambered.

If someone does bring out a 7mm on a long action using the .375 Ruger's head and body profile I hope they make the neck a little longer.

To add that if a big case is down the road twist it fast enough for the 180 VLD.

The above rifle misses the mark for me what with its muzzle brake.

Already have a custom 270WSM. Probably won't ever do another WSM anything....

The WSM case is not exactly in the same league as the ones I'm talking......

The 7 WSM has a short neck also........

I've no doubt new cartridges will become commercialized based on the 375 Ruger case. The 30 T/C case also.........

It would fall between the STW and RUM in case capacity

I think you will find it will be smaller than the STW. Probably closer to a 7mm/300 Winchester.

Nope.......

I think you'll find it will land right where I said, mate....grin

I say it would be a hellofaround, if that is a word. I have a large 7mm Cat and I love its performance.

I'm thinkin' it has big potential and could turn out to be better than the STW or RUM based on the case design......

Can't see it.Look at the 300 WSM.It's loaded to the nuts and a good handload 300 win mag exceeds it.Think the same for the STW vs the 7 Ruger.

Can't see doing silly things with the 375 Ruger case.

If they do anything with it maybe some calibers that ain't covered up with others, 416 and 35 come to mind.

What THEY do, don't mean dick. It's what WE do.......

7STW---bad comparison, though. The 300 Win has a greater case capacity than the 300WSM. With the 300WSM having the shorter, more efficient case. The Ruger case exhibits both advantages over the STW case......

I sure as hell ain't gonna play with the damn thing...

A 416 seems inevitable in factory form........

I'd have to weight water in one.That ruger case looks like a beltless 300 win to these eyes.Grain for grain whats the diff between the 2 is what I'd love to know anyone?Yet to see a ruger case myself to compare.

I'm thinking it would beat the STW in several ways, and perform more like RUM in a shorter package using less powder.........

101gr for the Ruger case. I keep finding conflicting info on the capacity of the STW case, with 98.3gr being the highest figure so far..........

The Ruger case is fatter than the 300 win case......

You could be rite.But untill the crony who knows?

The Ruger might suffer from pressure swings.....laffin

It should burn more powder, more efficiently than the STW....thus adding to the case capacity advantage.....

And your point is?

Are you trying to garner support for a project? Or are you trying to get someone else to do it and then you can say it was your idea?

You've stated a hypothesis. Now prove it! The only way to prove it is to build one. Are you going to do it, or do you just want to talk about it?

Yes the Ruger case is fatter than the .300 Winnie. But it's shorter. (And yes, I've measured it. I have a whole box of Ruger ammo in my hand.) And yes it has less body taper. (I've measured that, too)

As we all know: Case capacity equals velocity. Therefore, logic tells us that it will be more than the 7mm Maggie, and less than the 7mm STW. And probably very close to the 7mm Dakota. At equal pressures!

I say: "Go for it!" Some folks just have to pee on the electric fence for themselves. What are you going to call it? the 7mm2MG?

7mm barrels are cheap. 'Course custom reamers are upwards to $200 and custom dies are around $150. And then there's custom headspace gauges, and expensive brass.... But the upside is you can name it. (If someone hasn't already..... and they probably have... )

So you don't like the WSM but stretch it out a tad and it becomes a good idea?
