This is exactly why I can't stand youtube ninjas.
There are so many things wrong with his comparisons that I won't attempt to address all of them.
However one thing that's truly stupid is his velocity comparison between the prc and 7 RM with identical loads, he's excited that the 7 prc was over 100 fps faster with said load even though the case capacity is less than the 7 RM..
Well what a shocker
the bigger case didn't get a chance to reach equal pressure cuz there's more volume.
The last thing I'll rant about is the continued reference to faster twist rates with the prc, if homeboy did a Lil research he'd find a pile of 7 RM options with 8 twist barrels.
Obviously when it comes to factory loads the prc will have the advantage with heavier bullets above 175 grains, but he's comparing handloads and biasing the whole thing to make the prc look like there's a measurable velocity advantage when there 100% is not.
Ok I feel better now
Good night
