OK, silly question time.
I just got my 7mm 150 PT's delivered from SPS and they have the cannelure. The previous box that I bought locally doesn't have this. Is this something that's changed or do they offer different versions?
Does this line up with the partition for reducing pressure?
Last question (for now grin) When comparing, say, the 140 & 150 7mm partitions, is the extra weight behind the partition or spread evenly? I asked Nosler and they couldn't tell me. crazy

Sorry for the questions, but I'm a Partition newby.

Thanks!
