6mm Rem Ai Freebore question

[Plumsask]

Hopefully someone can shed some light, I picked up a 6mm Rem AI reamer for cheap, manson reamer with .025 freebore.
Anyone able to tell if I could still run the 90-105 weight bullets with this freebore?

Thanks

You're likely gonna want more freebore. Along the lines of .080-.100ish

Thankyou, I was wondering if that would be the case. As I'm not a gunsmith or barrel maker, can a competent smith cut the chamber and increase the freebore after?

Yes, but it's best done in a single setup or with a reamer that has the desired freebore. But yes, a good smith should be able to dial it in and do it in a separate op. Just give him a couple of dummy rounds, at least one with your desired bullet seated where you want it and a couple with the bullet seated long. I chuckle when I see reamer prints with a very specific number, like .104 for example. Freebore isn't a very specific number like that. It's just putting the bullet roughly where you want it in the neck. Most reamer prints are +/- .005 on length if that tells you anything.

Thank you for the help, much appreciated

With the Extra Long Neck of, the 6mm Rem Case,.. it, "Might" be, enough !
I'd make, a Mock up and Try it as you can always, "Lengthen", Chamber FB,.. Later.
My 6XC has, .104 FB and is, PLENTY but your 6 rem Neck is much, Longer,.. IIRC
Might "Compare" !
PS; your recommendation for, Berger 87 grain H-VLD's, in a .243 Win was, "Bang On" !
My grandson has shot 2,. Nice Muley's both, DRT !
This year he got a Huge heavy horned, 4 x 5,.. 30+ inches wide !

Thanks again, glad to hear the Bergers work for him. Ive also been using the 90 gr sierra tipped game kings in my heavy 6AI, my wife and I both have had great luck with them on whitetail and muley's.

I think you're right....get it chambered and see if it's not enough....get it throated.

Thanks
