Barrel length and twist
I would like some advice on barrel length and twist for a 25-284, thanks.

22" barrel 1-10 twist, that's my recommendation

22-24" with a 10" twist.

Try to look unimportant. Your enemy might be low on ammo.

10 twist and I would go 26"- might as well use the additional powder.

The rate of twist is determined by the longest bullet you intend to use.A 1-9 twist may work best with the longest ones. With a custom barrel,you can have it cut to any lengh, it doesn't have to be in multipules of 2".

Since the 25/284 represents an overbore capacity cartridge, it would be wise to stretch out the barrel as long as possible to get the gains intended. Or consider the 257 Roberts in a shorter length tube.

I have a 25-06 that has a slower twist and it will not stabilise the 120s. Even the 100s are poor unless I really stoak it up to max. Then I get really good accuracy, but nothing with the 120s.
