Build 6mm from 1960s Vintage Rem 222

I have my Fathers Vintage 223 Rem Model 722. I would like to use the action to build a 6mm variation unknown. Any Thoughts?

I am from Avella originally. I did not understand your Post, pleas ellaborate!

Many years ago, we, my father and I, had a 722 built into a 6mm-222 Rem.
My Pop was the inspiration because he shot Kangaroos commercially and didn't like the 223 cal for Kangaroos.
All was well with that wildcat, except it was VERY lacklustre and didn't like heavier bullets than 70g from memory, I was only 10 at that time.
Today I run a 222 Rem in a Sako L461 'Vixen'. Brass is hard to source, way pricier than it should be, but lasts many firings.
If I understand you correctly, a 6mm-222/223 will be a nice wildcat, but just be aware that brass is getting harder to source.
I also have another Sako L46 'Vixen' in 222 Rem Mag, haven't seen that brass listed for 10+ years.

Good luck with your build.

Cheers.

Without entering the realm of gunsmithing changes, the above is certainly a fine solution, 6mm-222 Rem or the 6mm-222 Rem. Mag.

Here is a comparison to start off the description. This is from a suggestion from Accurate Shooter quite a while back from a member Cheechako:




Dimension drawing .222 Rem.:



I've used the .222 Rem as well as the Magnum version for quite some time. This was at one time an exceptional benchrest cartridge until the PPC destroyed the market.

Then I discovered the 6x45 (.222 Rem) and the 6x47 (.222 Rem Mag) for depredation shooting. Easily suppressed, mild, low recoil, great accuracy when the gunsmith does his job.


This is a simple barrel switch and chamber job. No muss, no fuss, no mess! Although this isn't a speed demon that some might want, it has sufficient velocity when matched with the appropriate bullet for hunting small game and the smaller African antelope.

Enjoy!

I know this might not matter to you, but the 700 in 222 is a rare and valuable firearm
They made very few of them. Just something to think about. AND that gun is known for being very accurate as is.

If you really want to make it into a 6mm, then the easiest would be either a 6X45 (6mm-223) or a 6TCU. Both are very easy to source brass and bullets for and are excellent cartridges for mid-range shooting.

I shoot a Rem 788, with a custom heavy varmint barrel, 24 inch in 6X45. Brass makes a big difference. I weight sort Lapua .223 cases, and shoot the similar ones together. I also sort primers. Mine has a 13 twist, so I shoot 55 to 68 gr flat base bullets. LT-32 is my favorite powder in it. It shoots well with IMR-8208, VV N-133 and Benchmark, in that order. Use 205M primers.

It may have already been said but, you have a .223 bolt face, I don't know the exact measurement but will need to stay within that family of cartridges without a new (expensive) bolt.
Apologies if it has been mentioned.
