20” 6ARC bullet selection…

[black5.3]

Im in the process of assembling a 20” 6mm ARC upper and wanting to narrow down bullet selection and powder options for the uses this upper will see. It will be ran suppressed 100% of the time.

At first it will be scoped and do some load development/plinking. Probably later this year it will get a thermal scope and more than likely remain that way.

Im looking at a lighter bullet for speed and varmint hunting. Maybe something in the 70-80 grain class. I currently have Varget that should be suitable for what im trying to do but ooen to other powder options i should look in to.

Thanks for the helps gents. Also this will be a PVA Osprey barrel so im looking to get some rounds down it and see how it shoot.

Sharing the twist rate and any idea you have of the freebore dimensions would be useful.

There are some known decent predator/varmint bullets in 6mm, but the weight range will be dictated by the twist.

For example, the Berger 80 Varmint FB has a very forgiving tangent ogive that works well in many barrels.
Hornady covers the whole span from 65 grains on up.
Sierra has a new 90 TGK and also some from 55 grains on up.

The advice can be narrowed down by saying your twist rate.
