Howa mini for the tech gurus

Is there enough meat round the bolt rim to take a 6.5 Grendel to 308?
And what chance of a 20 dasher feeding from the mag do you reckon?

I thought the bolt diameter was the same as their 1500, just cut a bit out the middle, if so, there won’t be any trouble fitting

Can anyone think of a better option? I’m told there is an insert for ai mags to feed br cases. I’ve seen this howa mini in a chassis that takes ai mags and it’s cheap. I’ve played with howas before so it doesn’t feel rough like the thing I just got rid of

Trev,
Bolt dia of the mini is .617"
The clearance of a 308 case head bolt is .483"
That gives you .067" metal around the case head of the mini bolt now there is people on here that may think otherwise but I don't think that is enough.
I could see if a 20 PPC will feed out of the mag but what would be wrong with a 20 Grendel? I'm sure there would be a nane for it.
I'll be watching this with interest, let me know if you need anymore info.
Gary

Gary I got all warm and fuzzy a few years ago when I read about the 20 titan.

I want to use the same barrel and dies. Don’t want to have to find another reamer and another set of dies

I guess if I need an ai mag and an insert then a 308 action would do without the bolt face alteration

So I’ve put a deposit on a Howa. Anyone need a 20 inch 308 bull barrel

It will need a reamer run into it if they still screw them in to 5000ft/lb

Like the one I bought off Trev not so long back. So tight Darren had to run a parting tool just in front of the action ring

So don’t. Expect to sell the barrel then

As Darren said to me after pulling the barrel out of mine, "some do, some don't" its a suck it and see proposition

At 399 for a barreled action selling the barrel would be a bonus
