Hey guys,

Just looking for some info on my 308. Just picked up a bunch of 190gr Nosler CC's.

Lapua brass
CCI BR2 primers
Nosler custom competition 190gr
2.865" COAL

Looking at AR-Comp and RL17, Hodgdons site has plenty of info for 190 grainers.

Will be shot in a 24" 5R barrel Rem 700.

Thanks guys
SHM

What about going to Noslers site?

 

[thatguySHM]

As with their books, there's no pressure data, and RL17 isn't there.... Thanks for the help though!

47.8 is my max, but damn isn't it moving. I got a faint extraction mark there and my velocity was much higher than predicted @ 2755. I loaded for flat spot, starting 47.6 to 49.0. only shot the first two. Going to do load devolvement with 47.5 and adjust COAL to find my load. Same 100 yard POI as my 168 Nosler CC's.

Should be interesting to see what I can do at distance with this load..
