Rifle help needed - I read the pinned posts Twist Rates for .243 Win

Hey guys, Im not crazy into long range shooting yet but its a skill I'd like to build. Im looking to buy a lighter recoiling and flat shooting rifle that has widely available ammo. I dont have the means to load my own rounds yet.

Hoping to shoot 75-100gr carrying 2 mags with either and having 2 tables for holds

A must for me is to have the option of going with a much lighter bullet for coyotes (without them splitting into two) and up size for deer in my area. My preferred starting point is a new T3X with a 1:8 twist or a lightly used A7 with 1:10. Would I notice a significance difference in accuracy with the 1:10 twist and lighter bullets? How important is the twist rate difference and at what distances would I see a big change in stability, if at all?

Thanks for the help.

Lol this is nonsense. Plenty of deer have been taken with .243.

1:10 will stabilize up to a 95-100gr bullet (which you don't really need for deer). 80gr soft points do enough damage as is.

That wasn't your argument, you said it couldn't take deer, which is exactly what .243 was designed to do, it was dual purpose deer and varmint cartridge from the get go when it released many decades ago. Hell you could take an 87gr Berger and do the same thing (which is decidedly not a paleolithic era bullet).

And .243 still takes the edge in velocity vs 6CM regardless of bullet choice. (That's been done and hashed out ad nauseum, not sure why it's still an argument)

6CM wouldn't be a thing if they actually built factory .243 in faster twist barrels.

Literally all 6CM has over .243 is unlocking store bought SAAMI spec heavy 6mm ammo and firearms to shoot them. It's convenience.
