Grendel and 5R Rifling (Haters gonna Hate)

[XcountryRider]

Here's another example 120gr SST shot from a 18in PSA barrel. Hes getting 2525 fps (27.5gr AA2200). Compare to my factory 123gr Amax from my 18in Liberty/AR Stoner barrel at 2560fps. I'll need to drop that MV a bit for SST compared to Amax and you get the idea. Could he load a hotter load sure but it proves the point again that we are now in 6.8 starting gate territory and with the higher 6.5 BC its a different discussion than it has been.
