great plains rifle flint

[lead chucker]

Hey guys what flint size do you like with the lyman great plains rifle. I have one coming that should be here next week. I think 5/8 x 3/4 would work but not sure.

I think TOW lists the locks that their flints will fit best.
I just received a set of flints for my Blunderbuss that I am building with an L&R lock.
They fit perfect.
My GPR is a Cap Lock , so I am not sure which one Lyman recommends.
But I am sure Lyman can give you that info over the phone or by Email.
TOW lists a 5/8x3/4 for the Lyman or their ENG 5
