McGowen Precision AR-15 6-ARC build
#24
Trashy - before 6-ARC I’d of said yes but If you look at 6mm PPC and 6-ARC water case capacity difference it has no change in velocity (based on Hornady’s anemic data).

Stonehenge you missed my sarcasm on the 200 FPS comment - that’s 200 FPS faster than Hornady’s load data not necessarily actual MV in real life.

One benefit for the wildcatting calibers is that the one step neck down from 6.5 Grendel brass can use sturdier cases like Norma and Lapua - I.e. a little hotter loads can be run using the die setups and these brass types.

If you look at 6-ARC on the surface you don’t have that sturdier brass available yet and I don’t believe you can just downsize 6.5 Grendel brass in one motion with the 6-ARC dies although I saw a YouTube video this past week of a guy showing to do just that ...

I like all the speculation gents - it certainly is interesting how the Hornady marketing team has gone quiet the last month now that this data is released - it’s sort of hard to explain I suppose even for the “creators” of the caliber.

I’ll tell you this : if I were shopping for 6-ARC and had no previous knowledge of 6.5 Grendel and other 6mm wildcats and I saw the load data MVs I would pass - meaning Hornady would lose a possible customer and this forum would lose a possible new member.

The correct data IS that important !
