7mm-33Nosler

I would just use the 338 Norma case neck it down to 7 mm. The brass is a lot better. This was done quite a few years ago, look up the 300 Jazz or 284 Jazz

He has already addressed that and has a good reason not to do it.

The point is standard mag bolt face. Otherwise I'm looking at a m700 action with high bolt thrust or dishing out $1000-1300 for an appropriately sized action. I am building on one of the Ed Brown 704s being sold on this site and accurateshooter, just happens the gunsmith is less than an hour from me. So no .585 bolt face it's a .535 hence the Nosler case choice.

I think its a good idea, I have both a 33 and a 26 and have made up dummy rounds in a few calibers. If you are starting with a long rem action and want to seat the eld/vld long without a long mag box and machine work the 33 case would be a good place to start.

Sorry, missed that part.
Good luck with your project

The only "issue" I see is that the 28 Nosler already has more case capacity than the 33 since the 33 (and possibly the 30 too) had their shoulders set back to "prevent clambering of the 26 and 28 in the larger chamberings"
Everything else about it sounds awesome, although I think a 28-33 Nosler is a little bit more interesting personally due to the higher case capacity, and without having to get a lapua sized action. I've seen most people with the 28 Noslers get 3200+ (some cases nearly 3250) with the 180's, and 3150 with the 195's. I'm not sure I trust Hornady's claimed BC though, I trust Berger more to not inflate their BC but to be honest they're probably both a little bit inflated, someone with more time than me should verify the BC's of common high BC bullets for hunting and competition to see what companies inflate (and by how much)
Sorry didn't mean to thread jack, the 33-28 Nosler sounds pretty interesting, I don't see much of an issue with it.

What about the 7mm lrm gunwerks round? You can get loaded ammo, brass, dies and reamers already. Mine pushes 180 Bergers @ 3100 but that load kills brass in 3x firings. Back it down to 3050 and they last 5-6x.

Yep. I can get Nosler brass for the same price and better off the shelf dies that will work with this as a cartridge. I am not scared of a little case forming.

Sounds exactly like a 7 Dakota, cept you'll have a rebated rim. Should work out well for you!

That is one of the reason for the xx-Nosler's existence.

I just did some measurements with a 7mm 175 LRAB seated in a necked down 33 case. To put the boat tail right at the base of the neck the oal is 3.525". Thats a nice fit for feeding in a rem action without any machining work.

I believe this is the cartridge you are looking for:

Maybe/Maybe Not, what are the specs on that case?

 

[Smokinghole]

I'll see what happens when I get my stuff. There's always the possibility of using the 30Nosler as someone suggested. With a195 at the shoulder junction it's still only ~3.650".

I'll buy the reamer, and share the print/rent the reamer to whomever wants the same chamber and they can have their smith of choice chamber it or chamber it themselves Otherwise they're basically the same case. I'm not looking to make anything, not money or become recognized. Basically I want a longer 7SAUM and the the 35° shoulder is an added benefit. Rather than push a shoulder back, a 33Nosler or maybe 30Nosler case seems easier as a neck down and neck turn (which I do now anyway).

Heck if one went to CIP AICS length you could probably do what he did with a 338RUM case (shortest of the family), get a long neck and be seated out to 3.750. Not sure how much value the extra capacity would add for the work of pushing a shoulder back. Of course you could use ADG RUM brass which would be pretty killer. Makes me think.

Edited: finger editing grammar

I did a quick case sizing. I didn't try to dial in the die. I crunched a couple necks to get a good one. I need a couple more intermediary bushings.

A .30 Nosler might be a touch better with the shoulder ever so slightly pushed back.
