Talk to me about twist rates in a shorty 300 wsm. I called McGowan and the fella I spoke to recommended 10 and no faster.

 

[Ryan Avery]

I personally would go 1/9. It just gives you a little extra insurance if you want to go heavy with no down side.

1:10 will be fine to stabilize up to 220gr bullet at sea level with a velocity of 2730fps.
so if you hunt in low elevation and wanna shoot bigger than 200's get a 1:9 to be safe but a 1:10 will work

berger has a barrel twist calculator on their site if you ever wanna check.

Thanks, I looked at that, I was just wondering if there was some reason not to go with 9 twist. The McGowan fellow told me he'd still go with 10 twist even though I told him I wasn't planning on shooting any lighter bullets. ....?

I'd go with a 10 twist it'll stabilize up to 230 bergers no problem.
I recently got an 18" McGowan factory contoured tikka prefit with a .730 muzzle flare. It only weighs 2lbs, Im very happy with it using my 5/8×24 DT can

I have one coming. I went with 9 twist though. I do most of my shooting under 1000ft.

Was that a prefit? What did that run you?

Mine was $410. Same as 762 gunner's. They said 12 weeks.

Yep just screw it on and shoot, they were doing a 20% off sale when I bought mine so it was a real bargain

What bullets/powder you shooting?

 

[RGARNER]

.300 wsm is an awesome caliber

I like the caliber because I can load more of them in my clips in my fully semi automatic rifle. haha
I know the difference but the slang becomes common after awhile lol

It's a 7-300wsm improved using RL26
195s at 2725 verified to 1000 yards
175 ELDX at 2940 (still needs drop verified)

My factory Tikka shortened to 22” is getting 2850 the 205 EH.

Sorry for the slow feedback on this. I carried this rifle on several hunts but never shot anything with it. I did end up taking the can off and using a Ti Pro brake on it. I didn't like not spotting my own shots. It kicks likes a kitten now. I also swapped the stock to an XLR Element 4.0. I really love that chassis and now they inlet for a Bumblebee. The velocity for those asking above 2850 with the Berger 200x20.

I am going elk hunting with @Jim Carr at the end of the month so we should get some feedback on the 200x20.View attachment 365504

[mention]Ryan Avery [/mention] what magazine are you running with the Element 4.0 with the 200x20? Trying to put together a similar build and it seems that a long action is necessary for the longer bullets and haven’t found a magazine.
