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

[Phil Rizzo]

I've fired 3.5" shotguns that were worse.
It's more of a shove than a punch, as it is now.
If it was maxed out with 400gr bullets I suspect it would be all the above.
Big boar hogs are fun with A-Frames, never used solids on them though.

I have no clue, but probably this abomination

I had a buddy that had a .240 Rhyne. I recall it being a 7mmMag case necked to 24 caliber. It went somewhere in the neighborhood of 3500 - 4000 fps.?
Only thing 100 rounds later that barrel was toast.

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.

120 gr speer BTHP? pretty good BC

Lol, Nearly all of north dakota, south dakota, eastern montana and Wyoming, Nebraska, Kansas, Oklahoma, Texas...

Realistically, in Texas, Oklahoma, and New Mexico, you can rarely see over 200 or at most 300 yds. for hills, brush, timber, and the occasional mountain. Montana and Wyoming have their own terrain that limits sighting distance, but we won't get into that. Obviously, I am writing about hunting country terrain, not the view down the Interstate Highway.
