Alliant AR Comp for .308 Win

[NigelM]

Morning all,

Has anyone used Alliant AR Comp in .308W? On paper it seems viable but there doesn’t seem to be a huge amount of firsthand experience out there, at least this side of the pond.

Their loads for it are here - Alliant Powder - Reloader's Guide

In case you’re wondering, those are max loads and they say to reduce by 10% to find the starting load!

Also, any reason to go for AR Comp over Reloder 15/Ramshot Tac/CFE 223?

Cheers,

Dr. S

Talking to Alliant today and there is a RL15.5 on it's way. Couldn't squeeze too much detail out of them but it will be a temperature insensitive version of RL15. Could be perfect for this application as well of a couple of others I have.

My once-fired Lapua cases read 55.5 using a primer pocket blank and a tiny touch of washing up liquid to ensure full fill. I use a digital scale calibrated beforehand. Case volume and seating depth make big changes in pressure so I’m perhaps a bit obsessive...

Is that with a bullet seated

Ah that’s interesting! Any idea when it might be available? Although getting it over here with all that’s going on in the US might take an age!

I'm trying to squeeze that out of them but without joy so far. Sounded like imminent for the US so hopefully later this year for us.
