Deciding on a 22 and is the ARC really that great?

Both those explanations make great sense, thanks. So, in reading the 223 thread, Form kills a bull at like 802 yards and everyone agrees you can't tell the diff in the damage from a 300 or 7 or whatever. So knowing that, why do you say the 223 isn't suitable for the distances I suggested? 500 yds I think I said.

I'm not Form.... but the .223 drops below 1800fps between 400-450 depending on your density altitude which is the velocity threshold for the tmk to work with almost 100% certainty. In Form's case I believe they were testing to see what the bullet would do at a lower velocity threshold. If I remember correctly it was also a very controlled situation where he was using an mk12 AR so he could send bullets very quickly and he had an experienced spotter watching for him.

Folllowing as I made the decision to narrow the entire arsenal to 2 calibers. 22 &6.5. The 6.5 I am running a CM and Grendel. The 22 only have 223 and want a faster version as I “think” I will have an easier wind call. I don’t know and am looking forward the same information as the OP. Yes I am being a CS and trying to buy my way into being a better shooter beyond practice. I also can’t get the itch scratched for new toys.

In my opinion, and it's just that, speed is cool but drift resistance is a product of bc. Speed affects it some, bc effects it alot. Speed helps alot with terminal effect. Something about hitting a target with speed that amplifies the hydrostatic shock effect.

Im not a physics professor, I just observe alot of varmit funeral services. 17 hornet thru 6.5 prc
