6.5 Creed/ 260 Rem / 6.5-284 from a 20" barrel

Is there a whole lot of difference here between these three if all fired from a 20" barrel? Besides the 284 being a bit longer and the rifle a bit heavier ( looking at a rifle available in all 3)

I don't know much about the factory ammo available for the 6.5 – 284. I know it's out there but I don't know how much is available or who makes it other than HSM.
Simple answer is that I would go with the .260 Remington. But, that does not mean the other two would be a bad choice. So, take your pick, figure out what is most available in the bullets you like and go from there.
Kinda figured 20" was too short for the 6.5-284. Nosler and Double tap both make hunting ammo...bit pricey though.
Forgot to add, just for mule deer. Or sheep/goats if I win the lottery or somehow beat the odds on drawing.
Probably lean to the creed.

I've finally accepted being a brand snob is above my pay grade for a while, and so is doing the build I wanted to do
I think below 500, which I know means pretty much ANY chambering that rifle comes in, is doable. But, I've listened to you guys go on about the 6.5's for long enough, I wanna play too! I think below 500 should be attainable, as well. If I get drawn I'm going to do scouting trips over the summer and I'll have a better idea of the type of shots I may encounter. I did take altitude into effect when playing with a ballistics calculator, I noticed it made enough difference to matter.
Now.....that brings up a good Q for you Ernie (or whoever). I'm going to want to sight in my rifle for THAT elevation, how do I go about figuring out where on paper I'd be sighting in down here in the city?
It will estimate the hight of impact at 100 yards. There is your estimated zero at 100.
:-)
3.13 @ 100 for a 250yd zero.
I left everything the same but changed elevation from 12500 to 5300 and it pulled up 3.25". Not much of a difference for 100 so I should be safe as long as its consistently going just above the 3" mark here in town.
Naaaaa, yours was just shorter to type :whip2:
Good man.
Don't forget to look at the projected velocity upon impact. See where the bullet drops below 1,800 fps. That is your safe max distance.
The A-Max is reported to be effective below the 1,800 fps mark, but there's not much reason to chance it.
Remember, you are shooting a 20" barrel, so estimate you muzzle velocity accordingly. The higher BC bullets (like A-Max) will get you further and retain the speed needed. But, you know that.
By the way, heavy for caliber/high BC retains better than light for caliber/low BC. But, you knew that as well.
;-)
But, going by that 1,800 mark....that would be 900 yards with the SST
