Q. Building a new .303 Mauser?

How much work would go into, and how hard would it be to convert a Mauser 98 action to .303 British?
Those old rigbys made in 303 have me dreaming again, just wanna see if it's a feesable idea to look at going ahead with.

It might be possible to use components, such as the bottom metal and trigger, from a Siamese Mauser in such a project. Maybe that is what Rigby did!!! (Just joking).

No joking here..:LOL

I had a Rigby .303 and by looking at the Siamese Mauser triggerguard, magazine etc I see NO difference. Find a good Siamese Mauser and start from there.

Hmmm....I happen to have a couple of Siamese actions. Maybe a Rigby clone would be a good project.

Re: Q. Building a new .303 Mauser?

Sounds good to me. I built a .45/70 on a Siamese Mauser for a friend in Smithers - decades ago. What a wonderful rifle.
It used the same loads as my .458 (2") American, for exactly the same ballistics.

350gr. at 2,296fps
400gr. at 2,150fps
500gr. at 2,060fps

All with exactly the same load for each bullet weight, 68gr. H335 and CCI250 or Fed 215 primer. Both our chambers had a bit of freebore.
These loads were safe in our rifles, might not be in yours.

I have a project Mauser going in .303. I will be using a Siamese Mauser magazine/ trigger guard if it fits without much work. I'm using an intermediate length FN receiver.

Hi there,

I have a Mauser 98 in 303/25 which is a perfect candidate for a 303 Brit. It is a BYF 43 Oberndorf.

Whoever did the work knew what they were doing (except for the bolt handle) as it feeds very smoothly and the rifle is bedded and floated. It is not a pretty rifle as the bending of the bolt handle has been done bush mechanic style but it has a heavy barrel which was pristine when I bought it. The wooden stock is a bit rough but what impressed me about the rifle was that even though I had never reloaded for 303/25 and I used 87 grain pills made out of 22LR cases by The Bullet Factory, it shot a clovered three shot group at 100 meters so it made an awesome fox rifle.

I still have it after 10+ years but I would like to get the bolt handle redone and get a nicer stock for it. I bought a Bell and Carlson stock for it but ended up fitting it to my FN Mauser deer rifle.

It could be turned into a classic rifle with a 303B rebarrel and a nice classic styled wooden stock and some bolt work.
