What is the the most flat shooting cartridge yall can think of?

This was pretty interesting, it might be fun to slam a 1-8" twist 27" inch barrel on and play around with both, the .25-06 and the .257 Wby Mag using those 130gr plus bullets, of course, I see the .257 Wby Mag giving the best showing overall due to case. But, if this guys facts and findings are good, well, why not?
Cheers.

Split the difference and go 25-06AI or 25sherman

This looks nasty as hell for MPBR!!

 

[Roughrice]

That is a rare breed, indeed.
Anybody shot deer/pigs with em?

You talked me into trying some. 140's

I loaded some 140 RDF in Creedmoor for a friend to cull hunt on his ranch in TX.
He shot some broadside double shoulder shots that left a 1 1/2 - 2" exit up to 250 yards.
He said lung shots over 150 didn't provide enough expansion.

6.5-284, PRC, GAP or SAUM should improve that terminal performance.

That's good to know.
I plan on finding out firsthand, through my 6.5 max

You are running a 180gr 257cal bullet in a 257wby?

7-300 NMI shooting a 180 ELDM with a .385 G7 BC at 3330fps. That's pretty flat.

I am not do to have only a 7.5 twist. I stopped at the 163gr but if I would have done what my gut told me to do and go with a 7 twist then yes sir I would have been flinging the 180s just to see how they would do.

How are the 163gr doing? What sort of speeds are you seeing so far?
