[QUOTE="Lefty7mmstw, post: 2698480, member: 48043"] I've had way more accuracy issues with slower twist than faster twist. The exploding bullet thing is also way overblown unless you are dumping them through a fast twist 7rum or similar. I was working with 150 ablr pills when they came out and my 10" twist 7stw wouldn't stabilize them but the 9.25 on my Dad's 7stw was just fine. 10" is definitely too slow for spindly mid weights even in a 7stw. I have blown up some 168 and 180 Berger and 175-180 Sierra in my 8" twist 7rum when I started putting the cobbs to them. I settled on a 175 eld-x with enough H50bmg below it to pass 2900 fps. I could stomp it a good bit, but with a short throat and a fast twist I may see bullet destruction before 3100 fps anyway, so why bother. My 8" twist 7stw eats about anything rather decently but actually shoots mid weight pills like the 140 ab the best. The load I developed back in 2004 for my Sendero 7stw is still what I load to this day. My 7-08 is a Savage Striker pistol and she is fond of 154 Hornady fb and 150 bt bullets. It's not even really a fan of 140 Sierra's so I never did go lighter. My boy did kill his youth season deer this year with the pistol. 250 yards with a 154 Hornady launched at 2400 fps with I4895.
