Large caliber's on a standard length action

[Shawn.54]

He has approved of all the work I’ve done so far
and I always bounce my plans off him before I make chips he usually has been there done that and knows the outcome.
He also says that he got the idea of welding actions together from a article about H&H doing it when Rigby held the rights to magnum action.
I’m working on the 404 again hunting season is over and back on overtime at work that’s where gun parts money comes from.
So in the next few weeks I’ll show some progress.

Actions have also been shortened by cutting and welding. The region where the cut and weld is done in no way affects the strength of the action. The key is to maintain alignment throughout the procedure (for which a mandrel is required, made as a part of the process).

Yes that is what he did anything behind the locking lugs is to guide the bolt or cartridge no affect on strength.
On a different note if we look at the actions on the market today as entry level rifles they have a two piece bolt that has an amount of play between head and body which allows lugs to lock up with out influence of the body leading to the accuracy they have.

I think the easy approach to this question today is to choose the caliber to easily fit the action, or else choose the action for the desired caliber.

If someone wants a standard-length action like the Ruger Hawkeye (or M98), then limit the caliber to the 375Ruger, 416Ruger, or 458WinMag. (Yes, even more powerful wildcat options are available for the Hawkeye, like the 458 **NOT**PERMITTED** up to the 500 **NOT**PERMITTED**.)

If someone wants a long caliber, like the 375H&H or 416 Rigby or 450 Rigby/450Dakota, then get a CZ-magnum length action for the most flexibility.

Attached are some photos of two FN commercial 98 actions. Both are "standard" actions. One is as issued, the other has been opened up for H&H series cartridges. the basis of strength in Mauser rifles was to yield rather than break (see comparisons of WW I M98 vs Springfield 1903 rifles). Comparing the photos, one can see that most of the length was gained at the expense of the front lower locking lug.

Wow, the pics say it all. Is that about 5 mm off the lug ? The new lug shape looks pretty thin, I guess it works but as you say, it is just a matter of time.

9,3x64, 9,5x66 vom Hofe, 10,75x68, or .425 Westley Richards!

Ok, something special, but nontheless effectiv....

i have a 9.3x64 on a mkx mauser.
it has a 30/06 mag, no changes to the action other than open the boltface and extractor to suit the round.
feeds absolutely perfectly, and shoots better than moa when you point it right.
a right cheap rifle.

I just had a consulation with Reto Buehler, rifle builder, on the subject of building me a .404. He says that he magnum (.375 H&H length) Granite Mountain action works better - no alterations required and the rounds will feed better. For me, the perfection of feeding and extraction/ejection are convincing for a DG rifle. We are proceeding on that basis.
