So, About Bore Size Again...

Hi Folks,

I keep reading that the bore size in the Gewehr 88 is supposed to be 0.321" bore by 0.311" or so lands, and that the 0.318" bullet was a holdover from the blackpowder days, but that it was found this caused unacceptable gas erosion so they bumped the bullet to 0.323" to fit the bore.

Now, I've been shooting and cleaning, shooting and cleaning.

First time I slugged the bore I got 0.3165". Now I'm getting 0.318".

That's all well and good -- the crud's gone.

But, why are folks saying these are 0.321" by 0.311"? I do have the "S" conversion.

I'm sort of confused. Any help would be appreciated.

Thanks,

Josh
