22 ARC
- Thread starter Bfranklin
- Start date
I've only reloaded 88ELDm so far, Hornady brass & CCI450 mag primer
StaBALL 6.5, Viht N550, RL15.5ts, RL16, even RL26 with great accuracy
I have a pile of 62gr ELDvt and will try them with faster burn rate powders like LVR, CFE223, StaBALL Match, Varget, N140

I'm heading in the 22 ARC direction, I've got a 527 in 6.5 Grendel I'm going to convert over. I bought a box of ammo, just picked up some dies too. I've got 2500 virgin Hornady 6.5 Grendel, I ran a couple through the full length die and no issues bring it to 22 ARC in one shot.
Planning on a .985" straight IBI 1-7 twist.

How is this different from the 22 ppc? - dan
BR has the same bolt face measurement as the 308, apparently this has a slightly smaller than ppc bolt face. But not as small as the 223. Shoulder is a little bit forward compared to the ppc, so a little more case capacity looks like (after I posted I went and looked at the case drawings). Another cartridge designed to work best in the AR platform and magazine restrictions. I'll have to go see if there's any difference in case capacity between it and the 22 BR. - dan
22 & 6 Arcs are necked down 6.5 Grendel’s . Brs are std bolt face cartridges ans hold more powder .
Early BRs were slow twists and shot a lot of 68 grers
Now guys are using the 6 BR in F Class with FAST 1-7 to 1-8 twist barrels and deep throating them and shooting 105 -109 bullets !
Arcs are like the Ppcs but have fast twist barrel with deep throating for long heavy for caliber bullets ! 80 -109 gr
Very EFFICIENT cartridges

I am not seeing anything too abnormal, I can post up some specifics later

Yup, I am one of those guys.
6BR has been awesome for me. Became my favourite precision caliber instantly.
