I just looked on line & Magnum is also the top accuracy & velocity powder listed for 160 grs by Barnes.

Yep, used a pound in my last stw back when they called it BIG BOY. It was good, but nothing special. 3200'ish on 160 with fair accuracy. I keep going back to reloader with the stw.

Re: 7mm STW Brotherhood - For those who shoot the 7mm Shooting Times Westerner

Hello;

I talked with Frank at Bartlein barrels, about building two Custom Sako Rifles.
One with a never barreled Sako pre- Garcia Action and the other one on a Sako M85. Both in 7mm STW
Looking at Twist rates Frank said 1-9.5 would be good up to 175 gr and the 180 gr would require a 1-10 twist.
My question to you all, how would the 1-10 handle the lighter bullet wieghts ?
I looked at Layne Simpson's original article, which he stated the first rifle built
for the 7mm STW was with a twist rate of 1-10
I have a Custom .358 STA which is a beast and knocks the hell out of Elk size game , so I am looking forward to adding his little brother to the fold.

Tom

The 10 twist is borderline for the 160 and heavier But if its elk your after I would go with the 9twist and use the heavy bullet anyway ....you cant go wrong ....I took one with a 160gr nosler partion and she never took a step

Tom,

I think you need a 1-9 for 180s. A 1-10" could only work if velocity was suffecent to over come the twist deficency.

I'd build a 1-9" cause it could handle every bullet out there, except for the 195g Berger Hybrid that is due to come out where a 1-8" twist is needed.

I would go with the 1 in 9 to 1 in 9.5 for all 7 mm bullets.

If you go with a 1 in 10 you will have to stay with bullets lighter than 160 grains for consistant
performance.

The best all round barrel twist I have ever had for the STW has been the 1 in 9,25 eight groove.
It shot everything very good (I have never tried the 190s but they should do well).

Slower twist shoot well when loaded with the preferred bullet but can be very finicky and bullet selection can be difficult sometimes.
