Brian Litz' article often gets cited in the 7 vs 30 debate and it is never cited in context. First, he was writing to a BR audience and not a long range hunting audience. One factor he mentioned was recoil and again to a BR audience shooting numerous strings, not to long range hunters with braked rifles. Also, at the time of the article there was less selection of heavier high BC bullets like the hybrids in 30 cal.
I can pretty much guarantee that if Brian entered in this he would completely refute the idea that a " 7RM can out pound an 300 WM" in the long range hunting context.
It's really a no- brainer to anyone who doesn't have a cranial-rectal inversion that both 30cal and 7mm can be made to perform well, with the edge going to 30 cal because of weight carrying capabilities; though the average 7mm twist is a bit faster allowing for slightly higher sd bullets to be used- give them both either 9 or 10" twist to be fair and 30 kills 7mm in the heaviest/most aggressive pills that will spin. Given equal sd's and equal launch speeds 30 cal will out pound a 7mm every day (given similar bullet profiles) and twice on Sunday. Playing games with cartridges and barrels to favor one is just that-- playing games. I really don't care which is better to be honest as I shoot both and kill well with both; end of story in my book.
This is correct. Traditionally the 7 rifles have been made in faster twists which facilitated the development of longer high BC bullet and in years past the 7 generally had a much better selection of high BC bullets but the cal itself has no ballistic advantage over the 30 cal, and in fact a 215 hybrid requiring a 10 twist fired from a 300 WM will ballisitically beat a 180 hybrid requiring a 9 twist fired from a 7 RM using the same length barrels.
Idaho elk hunter is well known for his unsubstantiated rants with no data to back it up. And when asked for data he rants and babbles more but never provides data to back up his ridiculous claims.
