Bullet Weight for 7X57R in British Double Rifle - 05/28/19 04:47 AM

I just bought a Charles Clarke rifle built by Joseph Lang. It's a SXS hammer gun with Jones Underlever. The rifle was originally built as a .450 but sleeved and reproofed in Birmingham in the 1930s to 7X57R. I have a drilling in 7X57R and a lifetime supply of RWS brass in the caliber. I don't see anything on the barrel flats regarding bullet weight from the photos. (I haven't received the rifle yet). What bullet weight would most likely have been employed in the 1930s in a British double rifle in this caliber? Any suggestions as to where to start?

Correction: Henry Clarke. 4420 BAR. Proof pressure. That sounds more like the 80s than the thirties.

Vol,
Smart money would be on 173 grain bullets( or whatever you can find close to that).

YES
Start heavy, work to a lighter bullet
173 or so would be me choice also.

But the 275 Rigby also had a 140 grain loading

Superb in my circa 1950 Brno 7mm Mauser are Federal 140gr and Dominion 139gr.
