Rate of twist

Looking to get a long range gun.
I've settled on a bergara ridgeback in 6.5 prc . The twist 1:8

I just saw a Browning long range max also in 6.5 prc. Twist is 1:7

Both wear 26" barrels.
What reason would they differ in twist

Would they both perform. Just one is going to prefer a different weight bullet than the other.

What are the advantages of each.
Thanks

An 8 will handle most bullets including the 156 but a 7 would allow you to run heavier/,longer monos.

Elkaholic , you've got me asking more questions. 8s accuracy stops in the 150s.
Does 7 handle all grains including 150 and above.

Lastly what are mono bullets

Monometallics

These are usually bullets which are turned from solid bar stock on Swiss Screw-type lathes, now CNC. Often referred to as 'solids'.

The length of the bullet has more to do with twist rate than the weight and thats why the monolithic bullets (usually solid copper allow, not copper plus lead) require more twist. Copper is less dense therefore has to be longer to reach the same weight. If you plan on shooting monos that are heavy, you may want the 7 but a 7 twist can be hard on the jackets of some cup and core bullets. I would talk to Steve at Hammer about the weights you want to run and dont buy an 8 twist unless you need it.

I m going with the 6.5prc so . Bullets will probably be light. So the 8 twist would be ok. I think.

The 131 gr Hammer Hunter bullet was made for a 7.5" minimum twist 6.5 PRC.

So they would work in a 8 twist rifle ?

Or I need a bullet created for an 8 twist.

When referencing barrel twist rates 8" is not more than 7.5", it is less. You would need a bullet that is made for an 8" or slower twist. A number larger than 8 means it is slower.
