As for deer to 150 yards the bullet will carry enough power farther than that and then some. I have to admit that iron sights I am only good out to 100 yards or so. I have discovered of late that even zeroing at 50 yards is not as easy as it once was.

If you really want a DR in the same cartridge I believe there might be a BLE Double Rifle is the same cartridge on Gunbroker:

I looked at it a while back and did not see the JB with a crown anywhere amongst the proofmarks so I cannot confirm it is a Jules Bury made gun.

The store that has it could not confirm it is the 10.75x52r Springer versus 10.75x52R Grundig. I am not sure they understand the difference
