[QUOTE="Shootin4fun, post: 2065475, member: 28741"] And to emphasize, do not let your barrel heat up. In warm months, I even run bagged ice up and down the barrel a few times to speed up the process. Blowing 95 degree air through a warm barrel doesn't work very well. And yes, I let it sit after the ice to let the thermal even out so no cold spots. 168 VLDCH and VLDH with H1000 can be super accurate with SDs in single digits. RL16 also gave me great accuracy results but seemed temp sensitive and limited velocity. Still, at 2800 it's nothing to sneeze at. Check out Cal Zant's Precision Rifle Blog on exactly what you're asking about starting here: [URL unfurl="true"]https://precisionrifleblog.com/2012/10/18/real-world-velocities-for-7mm-remington-mag/[/URL] His blogs are just awesome.
