Why would anyone try to make reduced load .22-250?

It's been discussed so many times in the internet and here's my 2 cents, maybe it'll help someone.
I have a model 1895 spanish mauser carbine, made in 1899 originally chambered in 7mm mauser, then rebarreled to ".308" by the Spanish government, then rebarreled to .22-250 of all things by some unknown person or company.
If you don't know already everyone says these small ring Spanish mausers are totally unsafe to fire high pressure modern rounds like .308 or .22-250 or anything greater than 7mm mauser basically, due to bolt lug and receiver strength etc etc. I don't know how much of that I believe but it's a very old gun and I've tried to find a balance between safety and practicality.
My aim is to have a bullet leaving the barrel that at minimum acts the same as my .223 so I can chase goats and fallow deer like I always do.
Assuming max CUP pressure for 7mm mauser is 46000psi and max for .308 and .22-250 well exceed this it sortof makes sense, not sure how scientific this really is though.
Aiming for that number I've gone with 30.5 gr of h335 behind a 55gr projectile, which should be making 44,400 CUP while still sending that little projectile way past 3000fps. I got this data from hodgon website and it's the "starting load" for that powder.
After testing on paper it's sufficiently accurate, and now I can confirm it's also got the power as 1 shot dropped this buck where he stood.
Anyone else too-tooed with these beautiful little rifles?

I like your way of thinking and do love the look of that rifle. A few even gentler trail boss loads will be your friend if need to finish something off up close...22-250 is a lovely round but unsuppressed they a tad anti social .

Absolutely it's bark and flash could probably kill even if you missed. Nice idea with trail boss if I could bloody find some!

Is your rifle .308 Winchester or 7.62 x 51 or 308 CETME . All differant cartridges

Its a 22 250 isnt it

Yes it's a .22-250, barrel was installed aftermarket. It still has the old markings on receiver from when it used to be a .308, and all it says is "308". That's the age old internet debate I'm sure the Spanish government meant it to fire only 7.62 NATO or perhaps the cetme version but didn't think that writing .308 on it would confuse future hunters, but that's just my opinion.

Apologies - it is indeed. Ignore my earlier comments then.
