Picked up a 25 Bob this week. I've never owned one but did assemble some loads for a couple 20 years ago or so. I see reg 257 brass and some designated 257 +P.

A. What is the difference?
B. Can you run +P data in non+P marked brass?
C. Is Nosler brass really worth $1+ per case?

I plan to run my Bob at 'modern' pressures (+P data). 25 Bob brass is a bit pricey so don't want to screw up my brass purchase.

Any good Bob data with 100 TTSX and/or 110/115 Nosler PT?

Thanks.
