Berger 185 grn hybrids

RL 17 and a stiff load at that! They'll fly just fine. Not that you should try this!!!!!!!, but I don't know you can put enough of it behind a 185 in a 308 case to see viable pressure signs, unless your seating boattail only in the neck. Awesome powder with results for heavies;)
 
I think the real answer will come from your rifle. They WOULD NOT shoot out of my 1:11.25. But the 208 amax will. The only real way to know is to try them out. You could always order a sample packet from
