Twist rare can be a bit of a qualifier,
Do you mean for hunting or targets?
I see you put this in the 'Bullet Making' subforum - are you planning on turning your own?

I like 120gr-140gr in the 7mm monolithic category.
Copper has lower density than lead, so dimensionally a 130gr mono works out similar to a 160gr conventional 'cup and core' bullet.
Anything heavier may need a fast twist to gyroscopically stabilize - this is related to the LENGTH of the bullet. If building from the ground up, there is no reason NOT to go with a 1:8 twist barrel - a typical 1:9 may limit you some.
Copper resists deformation better than lead, so a little extra velocity helps with expansion in a hunting context.
Sounds like fun, what kinda lathe ya got?

No problem, there is a lot of terminology -
Generally;
Reloading = Making ammo
Making bullets refers to the projectile itself - casting lead or turning copper.
As Lefty #### mentioned, you are likely to get better and more cohesive responses if you start a thread introducing yourself, telling us what kind of experience you have and where you'd like to go.
3 different thread on 280ai is a bit cumbersome, tand without any context it's difficult to provide a complete answer.
Starting a thread like "Help me build my first 280AI" in the Hunting and Sporting arms might be your best bet.

I hunt with a 280, a 140 gr bullet has done the job from Deer to moose. The AI will do about the same. Practice with the bullet you hunt with and no problem. I shot 175 nosier partition as I had lots, they worked very well but need to know POI at your ranges.
