The velocity posted for 125 and 130 grain bullets appear almost identical to the 6.5 Grendel, how would a 300 be an advantage?
If you are looking for flat trajectory, it's not.
If you are looking for something that can consume pistol powder & still shoot like a rifle, it's THE game.
If you have a bunch of light .30s laying around from days of reduced loads for HP, it's the ticket. I seem to see more good deals on small .30 bullets than on 6.5 bullets. Maybe it's just because I look at .30s more.
The brass is free. You can pick up good .223 brass at any range. I have my trimmer chucked to a drill & it only takes a few seconds to trim & then size the brass.
Bill Wilson seems to think it's a better round than the Grendel out of SBRs due to the faster powder it can use. True? I don't know. I wasn't interested in an SBR.
You gotta remember your audience here. Finding brass on the ground IS justification for buying a new rifle!
Oh, and thanks for bringing up the Grendel.
You may be the one that FORCED me to buy one!
