[QUOTE="mrultramag, post: 823768, member: 4467"] W/RL25, I would start around 71-72 gr and work up from there. Usually max is found to be around 74.5 to 75.5 gr. I think the best accuracy I got was around 3400 fps. I think I ran them as fast as 3450. I was using WBY brass, Fed 215M, OAL 3.250 in a vanguard sub-moa. its a 24" bbl. So if you have a 26" bbl you'll see a little more speed probably. [/QUOTE]
