Getting there, slowly, chrongraphing and precision testing is a chore in this weather.

Re: Ruger Mini-14 chambered in 300 BLK
The barrel is a 1:8 lothar walther, 23mm in dia. For about 4", then 20mm out towards the muzzle.
This project seems to have a great accuracy potensial, but, it will not cycle yet, not with the vit. N110 loads.
Considering larger gasport or vit.120 powder.

Re: Ruger Mini-14 chambered in 300 BLK
A update.
Loading is bit of a chore, there is absolutly no factory ammunition available in my part of Europe, that means that developing near max loads is a bit of guesswork. I have tried N-110, this gives me good velocity, but not enough gas to cycle the rifle, i am now on to N-120. This cycles the rifle with supersonic loads and a silencer.
My next trials will be with near max loads with N-130.
The scope mount rail, no, its not glued on, some fancy milling and two M5 screws.
Nosler 168hpbt @ 1670fps V/0
The same load.
Nosler 155hpbt. @1590fps V/0
I guess i am on to something.

Re: Ruger Mini-14 chambered in 300 BLK
Yes. It works, with both supersonic from 110 to 175, and with subs and supressor from 200.
The trick for the supersonic was Norma 200.
i will get back when i have sorted the data.

Hi Egon, did you try once with 11grs. 5744 and 220grs.SMK? I think that should cycle your Mini-14 reliably.Egon Olsen wrote:Yes. It works, with both supersonic from 110 to 175, and with subs and supressor from 200.

Re: Ruger Mini-14 chambered in 300 BLK
Did you have to open up the gas port substantially to get subs to cycle?

Libertyswiss, thank you, i will try that.

Hello, Egon. Do you have any updates?
Anyone else taken on the challenge?

A Mini-14 in 300 Blk would be the ultimate 'piston' system without having to convert an AR, and the Mini-14 is strong and basic and reliable. Think Garand with a detachable magazine, and in a 'mini' version.
I would like one of these someday...
