I do enjoy shooting my 7mm #5 Rolling-Block. It was made around 1908-1910 and has a simpler rear-sight, than Jeremy's.

I use 'starting' loads with 139 grain projectiles to get the cartridge cases nicely formed to my rifle's chamber. Thereafter, I neck-size only.

The early Mauser and Remington R-B rifles in 7X57mm have different chamber dimensions than what was later utilized by U.S. manufacturers.

I keep meaning to buy and install a lighter trigger-return spring. My trigger-pull is quite heavy, but, the lighter reproduction spring should be an easy 'fix'.
