Hi all,

I am considering getting a falling block rifle built for myself, most likely on a Hagn action.
My question is: are falling blocks best suited for rimmed or rimless cartridges?
Probably, I will go for 7x57, but should it be 7x57R? There are a lot more choices in the rimmed version, due to the large number of combination guns using this caliber.

Any help is much appreciated? Thanks.

Marcus
