Dakor, the 156 cauterucio bullets are hand made by Bob Cauterucio. They are great bullets. The BC is 615.
His 176 have a bc of .750 but Bob says a 7 or 8 twist is needed to stabilize them. Some folks here think a 9 twist would work but with a 10 twist I'd try the 156's. If you didn't build the rifle yet then go with the 9 twist. If your shooting inside of 1000 yards the 156's will be fine. I tried 140's in my 7STW, they where too fast. Slow'em down and increase accuracy.
Like I told Bigbore, don't be a velocity freak. Brett Farve doesn't throw a 60 yard bullets pass does he?
Bigbore, glad you are going with those heavier BC bullets.
Does cauterucio bullets have a web page? I did a search for them on Google and did not come up with a home page for them. My rifle does like the 160 Accubond and I get 3252 fps with them and groups under 1/2 inch at 100 yards. I have not had time to shoot them at long range but I think they would do well. I guess I could go with the heavier bullet its hard though when you are hooked on screaming velocity's. [img]images/icons/grin.gif[/img] Has anyone tried the 175 Nolser Partition at long range? My rifle loves them and they have a bc of.519 and a sd of.310. As for the berger 180 I dont think they will work in my rifle because I have a 10 twist. I am going to buy some Sierra 175 Match Kings and try them to see how they do.
You might also look at the Lost River Ballistic Technologies web site. They make a J36 hunting bullet that is LONG and all copper with a driving nose tip. BC for the 140 is .644, 160 is .715. I've not shot their bullets, but have seen several good reports. [img]images/icons/wink.gif[/img]

Re: 7mm Bullets for Big Game
If you have a 7STW with a 1:10 twist, you are really limited to monometal bullets of around 120gr if you want decent terminal performance on closer shots. Jacketed bullets up to 140/150gr will probably be OK as well but meat damage will be high. There are 120gr turned copper bullets available that will run 3800+ fps from your STW for shooting inside 500 and 130gr bullets for shooting further out. No one bullet will be good at all distances as the requirements are not compatible.
