Your Sendero should have a 9.5" twist. [img]images/icons/rolleyes.gif[/img]

Re: My STW and the 162 A-MAX

I'm needing to come up with some good justification as why I want to rebarrel my 7 Remington Magnum to 7 STW.

Any help you folks could give me would be greatly appreciated.

Unless your 7 mag is shot out, don't bother. It's nice to get the extra zoom out of the big case but you will pay the price with a short lived throat.
I'm thinking of rebarreling to 300 Wby, which should provide a little more power AND better barrel life than the 7STW.
Just my 2 cents. [img]images/icons/grin.gif[/img]

Re: My STW and the 162 A-MAX

Tim I have tryed on numerous occasions to rechamber used 7rem mag barrels from various makers and have had poor to say the least end results. I don't know why but it just never seems to work as well as new chamber in a new barrel. My advice is to either leave your 7 rem alone or to spend the money and rebarrel properly. Be aware that the STW is like a 220 Swift in respect to the life expectancy of the barrel. Is 200 fps really worth the expence? I have built several of both STWs and Rems both shooting 160 gr bullets the difference in velocity across the cronograph was an average of 270 fps with good accuracy.Certainly you can get more fps but generally the grouping increases in size
Long Distance is BETTER than being there

Re: My STW and the 162 A-MAX

Varmint Hunter,

Been very happy with my 300Wby. Suggest trying the 155gr Amax in a 1 in 12 twist or similar. This combo flies way flatter and drifts less then expected. Much better then the 168gr (amax, nosler J4, ballistic tips) I have tried in my rifle. My muzzle vel is 3200 to 3250fps with the 155 and 3100fps with the 168's.

For a plinking/varmint load, I am sold on the 155 Amax bullets. Shot this combo to 1800m (1960yds) a couple of weeks back. Bullet stays stable.


Look at some recent reloading manuals (Nosler #5) and you will find that there is not that much difference in performance between the Rem and STW. The Nosler manual actually lists the same vel for both.

From a long barrel rig, the STW will shine but in a 26" barrel, wouldn't bother. Lots of barrel wear, recoil, noise, component consumptions and 100 to 150fps more...maybe.

The 7 Dakota would be a good choice. Maybe a shortened ultra mag. These would be the same as the Rem without the belt. The short magnums (Win and Rem) won't be able to perform like the reg. 7mm Mag when using heavier bullets.

Good luck...
