Intresting the way this thread has gone, I kinda like the 1/4 bore, currently own a finlight 2506, shot a few deer, goats etc, worked as well as anything else, I have used, But the old 2506 is limited a bit with a short 22" barrel and likely no faster that a 257 Roberts.
Shot a few deer with a 250 savage, another old but capable deer cal.
Only about 3g difference in powder capacity, between the 243 and 257 bob, so really not a lot of difference, the bob being able to handle heavier bullets at sensiable speeds. 110gr accubond at 2900 ish.
The 1/4 bore, is the dog, in long range bullets, no one makes a decient BC bullet, good enough to 400 , after that pick some thing else. 6.5, 7mm etc.
Local gun store selling cooper fire arms, said he sell lots of .257 Roberts, and even more off the improved version,
I would like one, in a win M70 featherweight, but already got a featherweight in 7x57, so no real need.
As the starting poster asked about 22-250, I had two and sold them both off, might have kept one, but the 1-14 twist is a handicap, they are too noisy and expensive for varminting, great for long range predator hunting, If either of mine would have been able to shoot a 70-75gr bullet might have keep it , but I traded them off for a New CDL 6mm Remington.![]()
