Christensen .300wsm Ammo / Twist rate ?

[Wildatheart]

I have been looking for ammo for my new Christensen .300wsm. New to these guns and long range but have been doing extensive research.. I can’t find the right Grain weight for the 1/10 twist rate they all recommend 1/12 twist.. like HSM & Copper creek custom ammo. Does the twist rate they recommend really make a huge impact? Looking for 180-210 Ammo. Any advice on this setup and what to use? Thanks for your time

1 in 12 is minium. A 1 in 10 is faster and will stabilize anything that recommends 1 in 12.

Awesome... makes sense. Solves my problem quickly. Thanks

Anyone know how to determine the year of manufacturing of a Christensen ridgeline?

I've used the Berger twist rate calculator successfully on a couple rifles.
It spits out a number and the higher the number the more stable.
It's been spot on all 3 times.

I shoot 180 grain Barnes TTSX handloads in my CA 300WSM. Makes 1 ragged hole at 100 yards and holds half MOA to 300 yards (farthest my range goes). I intend to work up a load for 200 grain pills this Spring. You should be fine with 180 and 200 grain bullets.

If you're interested in reloading, I have the same rifle and did some extensive testing.

300 WSM Load Development

Last year I took a decent bull using factory Nosler Trophy Grade 180 Accubonds and my 300 WSM CA Ridgeline. I was a little confused with the performance of the AB. My first shot from 175 yards, freehand, was high lungs, shattering the opposite side scapula. The bull took off and disappeared...

Would you mind sharing the load data?

Norma brass, Fed 215M primers, Barnes 180 gr TTSX, 68 grains H4831SC, CBTO 2.21 (COAL 2.835).

The above load is fairly hot. As always, work up slowly in your rifle. I have since moved away from Monos but the above load served me well on a bull elk a few years back.
