I fired more rounds than I would have liked trying to find reasonable accuracy with acceptable velocity. When I changed primers from Federal gold medal 215 to Fed 210 match I got what I wanted. Using N560 powder with Hornady 117 SST's 3350 FPS and great accuracy. Just as good Nosler 115Bal tip. I'm sure there will be many nay sayers but I'm happy.

Did the 210s help with accuracy or velocity?

I have been kicking the idea around of going down to 210s to see if I can squeeze some velocity out of a load.

I switched from 215's to 210's and everything tightened up for me in 300WN. I know it's not the same caliber but I got really great accuracy out to a 1000 yards and extremely tight ES and SD, every other component stayed the same.

Here are some pictures.

By any chance can you send one more pic of this? The 115 VLD section has a glare from the flash lol.
