Classic caliber with a twist

[Ronin]

This is a bit different - when one thinks of 7mm Mauser (7x57) a classic walnut stocked piece is imagined

Anyway - the client specced caliber with the additional requirement of lightweight, accuracy with modern materials

So after some discussion the following spec was settled upon ;

Borden Timberline -right bolt, oversize bolt knob, right port, Sassen stainless barrel, 8 twist, spiral fluted, finished at 24” with protective cap covering m18x1 mm thread

Triggertech diamond trigger

MDT HTN 26 Carbon folding chassis

Barrelled action ceracoated titanium grey by Liquid Steel Design

Client yet to report on accuracy but I’m “reasonably” sure it will hold its own with unerring reliability


A few images

Ronan - A couple of questions please (well 3 actually) arising from the pictures : -
1. Is there any advantage in spiral fluting as against straight fluting or vice versa?
2. If spiral fluting is preferred, should the spiral be with or against the twist of the rifling in the bore?
3. Should the twist rate of the fluting be the same as the twist rate of the rifling?

Don’t recall ever being in a boy band,,,

Purely aesthetic on all counts

Pretty is good

7x57 was one of the first “modern” centre fire cartridges

Herr Mauser got it right first time.

Chambering aside, what was/is your Client’s driver for such a takedown friendly specification if other than a need to carry on London Transport?

May I also assume the barrel coating was applied after install of the ‘invisible’ moderator thread cap?

You simply can’t do that to a 7x57, there’s a place in gun hell for you Sir

I didn’t say it was invisible it’s a protective cap

Yes coating applied after proof as sometimes weapons can be damaged at proof

Lightweight and portable this certainly is

I’d be surprised if the scoped weight is more than 8 lbs

Interesting! The timberline is the intermediate length action for the x55 and x57 length cases?

Lovely looking rifle. Well put together as always.

Very nice Ronin!

 

[shakey jake]

isnt 7x57 a chambering? the calibre is surely not old or new.

The Timberline is a long action

It’s a chambering yes - quite old - served the Boers well in Afrika
