[QUOTE="Calvin45, post: 2767243, member: 109862"] According to science 🤓 ! One thing I have always wondered…do short fat cartridges actually do any better out of shorter pipes OR is it all just a matter of the chamber being included in barrel length??? A 300 h and h and a 300 wsm with the same barrel length will see the hh bullet starting its journey about an inch closer to the end of the pipe. And I constantly see 25-50 fps per inch as an internet rule haha. [/QUOTE]
