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

My Laredo ...or should I say Black67's Laredo is a factory 9.25 and it is awesomely accurateI 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.

I have just started reloading and have 7mm stw I want to reload for any suggestions for bullets and powder combinations to start with for hunting whitetail deer in North Carolina. I don't know rate of twist for barrel I bought it used and is Weatherby mark v deluxe action with custom barrel. If somebody could tell me how figure out the twist I would as I know it is important for bullet weight selection. Also does anybody know a good place to get brass for it?
