[Savageseven]

HELLO everyone im wanting to build a 6mm prc for varmint shooting. im torn between the 70 grain nosler ballistic tip and the 80 grain ballistic tip and the sierra 90 grain tipped game king bullet. which one would you choose and why ? also what velocity should i expect ? what freebore do i need for these bullets listed ? and what powder would work best ? and what twist would work best ?

Better BC with the Sierra.

I'd look at the Hornady ELD-VT for starters.

what twist would you go with ?

They recommend an 8" minimum due to it's length.

 

[Savageseven]

An eight twist will spin 103, 105, 108 Berger & Hornady.

 

[Savageseven]

i would think a slower twist would be best for 80 grain class

do the 8 twist / I'm using n570 with 103 gr KH bullets, don't have my book available at the moment, im thinking it was safe at 3300, in a 24" krieger.

Personally I would go 8 twist. Then you could shoot most any bullet you want. The barrel won't last long so you could change twist rate in short order.

You need to know the twist rate of your barrel (in order to stabilize the bullet). Depending on the typical distance of your target, speed is good on a calm day and mass is good on a windy day.

I havent even bought a barrel yet. im trying to decide if i wanna shoot the 80 grain nosler ballistic tips or 87 grain v-max or the 90 grain sierra TGK from there i will match the reamer freebore to the bullet and the barrel twist. i was hoping to get feedback one guys using the 6mm prc for thermal hunting and what bullet they liked most.

I'd look at the 90 TGK.
I've been using Sierras 100 gr. In a couple 6mms and they plain shoot also their 140s in 7mm.
