BC....

Same bullet.

The bottom is the 133 in the RPM.

The top 2 are the 117, same bc, and the -06 shows a faster start (albeit 50fps) than the RPM.

BC....

It’s the same bullet for both in it. I’m guessing they have the two cartridges flip flopped in the numbers

They should've necked the 7PRC down to 257 but I get why they wanted to use a proprietary cartridge as their base rather than a Hornady one.

The 7 PRC is real close to 257 wby case size. They don’t want to say “it’s like our classic but in a better case designed by hornady and with a fast twist.”

I like it. Doubt I’ll ever build one but I don’t like wildly overbore and this should be enough to be impressive without gettin too crazy.

I’ve had both the 25-6.5 and the 25-7 built. The 25-7 is almost exactly what you said: a modernized 257Wby. The 25-6.5 is a modernized 25-06, maybe 25-06AI. Case capacity is so close that I used 25-06 load data as starting points for my own.
